Old English grammar

Old English still had all three genders of Proto-Indo-European: masculine, feminine, and neuter.

Each noun belongs to one of the three genders, while adjectives and determiners take different forms depending on the gender of the noun they describe. The word for "the" or "that" is sē with a masculine noun, sēo with a feminine noun, and þæt with a neuter noun. Adjectives change endings: for instance, since hring ("ring") is masculine and cuppe ("cup") is feminine, a golden ring is gylden hring, while a golden cup is gyldenu cuppe.

Perhaps the strangest aspect for modern speakers is that the words for "he" (hē) and "she" (hēo) also mean "it." Hē refers back to masculine nouns, hēo to feminine nouns, reserving the neuter pronoun hit for nouns that are grammatically neuter. That means even inanimate objects are frequently called "he" or "she."[4] See the following sentence, with the masculine noun snāw:

Compare this parallel sentence, where the neuter noun fȳr is referred to with hit:

Only a few nouns referring to people have a grammatical gender that does not match their natural gender, as in the neuter word mæġden ("girl"). In such cases, adjectives and determiners follow grammatical gender, but pronouns follow natural gender: Þæt mæġden sēo þǣr stent, canst þū hīe? ("The girl who [feminine] is standing there, do you know her?").[5]

When two nouns have different genders, adjectives and determiners that refer to them together are inflected neuter: Hlīsa and spēd bēoþ twieċġu ("Fame [masculine] and success [feminine] are double-edged [neuter plural]").[6]

Nouns referring primarily to one sex, such as fæder ("father") and mōdor ("mother"), usually have the same gender as what they describe. Hence cyning ("king") is masculine and cwēn ("queen") is feminine, munuc ("monk") is masculine and nunne ("nun") is feminine, etc. The three major exceptions are wīf ("woman") and mæġden ("girl"), which are neuter, and wīfmann ("woman"), which is masculine.

If a noun referred to both males and females, it was usually masculine. Hence frēond ("friend") and fēond ("enemy") were masculine, along with many other examples such as lufiend ("lover"), bæcere ("baker"), hālga ("saint"), sċop ("poet"), cuma ("guest"), mǣġ ("relative"), cristen ("Christian"), hǣðen ("pagan"), āngenġa ("loner"), dūnsittend ("mountaineer"), selfǣta ("cannibal"), hlēapere ("dancer"), and sangere ("singer"). The main exceptions are the two words for "child," ċild and bearn, which are both neuter.

However, nouns referring to things weren't so predictable. They could be any gender, almost regardless of their meaning. For example, seax ("knife") is neuter, gafol ("fork") is feminine, and cucler ("spoon") is masculine.[7] Even nouns which mean the same thing often have different genders: beorg ("mountain") is masculine while dūn is feminine, steorra ("star") is masculine while tungol is neuter, ēagþȳrel ("window") is neuter while ēagduru is feminine, trēo ("tree") is neuter while bēam is masculine, sċieldweall ("shield wall") is masculine while sċieldburg is feminine, etc.

That said, there are still ways to guess the gender even of nouns referring to things:

• Nouns ending in -a are almost all masculine. The exceptions are a small number of learned borrowings from Latin, such as Italia ("Italy") and discipula ("[female] disciple").

• Compound words always take the gender of the last part of the compound. That's why wīfmann ("woman") is masculine, even though it means "woman": it's a compound of wīf ("woman") plus the masculine noun mann ("person").

• Similarly, if a noun ends in a suffix, the suffix determines its gender. Nouns ending in the suffixes -oþ, -dōm, -end, -els, -uc, -ling, -ere, -hād, and -sċipe are all masculine, nouns ending in -ung, -þu, -nes, -estre, -rǣden, and -wist are all feminine, and nouns ending in -lāc, -et, -ern, and -ċen are all neuter. Mæġden ("girl") is neuter because it ends in the neuter diminutive suffix -en.

• Letters of the alphabet are all masculine. Metals are all neuter.

• Animal names that only refer to males are masculine (e.g. hana "rooster," henġest "stallion," eofor "boar," fearr "bull," ramm "ram," and bucc "buck"), and animal names that only refer to females are feminine (e.g. henn "hen," mīere "mare," sugu "sow," cū "cow," eowu "ewe," and dā "doe"). The only exception is drān ("drone"), which is feminine because most people didn't know drones were male. However, the general names for animals could be of any gender: for example, ūr ("aurochs") is masculine, fifalde ("butterfly") is feminine, and swīn ("pig") is neuter.

• Adjectives used as nouns, such as colors, are neuter unless they refer to people. When they do refer to people, they're masculine by default unless the person is known to be a female, in which case they duly follow the feminine inflections: fremede ("stranger"), fremedu ("[female] stranger"); dēadlīċ ("mortal"), dēadlīcu ("[female] mortal").

• Likewise, verbs are neuter when used as nouns.

Old English has two nouns for many types of people: a general term which can refer to both males and females, like Modern English "waiter," and a separate term which refers only to females, like Modern English "waitress." Several different suffixes are used to specify females:

• -en is added to miscellaneous words such as god ("god") → gyden ("goddess"), ielf ("elf") → ielfen ("female elf"), þeġn ("servant") → þiġnen ("female servant"), þēow ("slave") → þīewen ("female slave"), and nēahġebūr ("neighbor") → nēahġebȳren ("female neighbor").

• -estre is the female equivalent of -ere and -end, both meaning "-er." It is used on many nouns such as sangere ("singer") → sangestre ("female singer"), lufiend ("lover") → lufestre ("female lover"), bæcere ("baker") → bæcestre, tæppere ("bartender") → tæppestre, and forspennend ("pimp") → forspennestre.

• -e is the female equivalent of -a, which was sometimes a regular noun ending with no meaning and sometimes yet another suffix meaning "-er." Examples include wyrhta ("worker") → wyrhte and foregenġa ("predecessor") → foregenġe.

Sometimes the female equivalent is a totally separate word, as in lārēow ("teacher") ~ lǣrestre ("female teacher," as if the general term were *lǣrere), lǣċe ("doctor") ~ lācnestre ("female doctor," as if the general term were *lācnere), and hlāford ("master," literally "bread guardian") ~ hlǣfdiġe ("mistress," literally "bread kneader").

As in several other old Germanic languages, Old English declensions include five cases: nominative, accusative, dative, genitive, and instrumental.

• Nominative: the subject of a sentence, which carries out the action. Hē lufode hīe ("he loved her"), þæt mæġden rann ("the girl ran"). Words on the other side of "to be" also take this case: in the phrase wyrd is eall ("destiny is all"), both "destiny" and "all" are nominative.
• Accusative: the direct object, that which is acted upon. Hē lufode hīe ("he loved her"), sē ridda ācwealde þone dracan ("the knight slayed the dragon").
• Genitive: the possessor of something. Ġesāwe þū þæs hundes bān? ("Have you seen the dog's bone?"). This case was much more frequent than the possessive is in Modern English, because Old English had no word for "of." Hence "the fall of Rome" was Rōme hryre, literally "Rome's fall," and "the god of thunder" was þunres god, literally "thunder's god." It was even used partitively, to signify that something was composed of something else: "a group of people" was manna hēap (literally "people's group"), "three of us" was ūre þrī ("our three"), and "a cup of water" was wætres cuppe ("water's cup").
• Dative: the indirect object. Iċ sealde hire þone beall ("I gave her the ball").
• Instrumental: something that is being used. Hwæl mē meahte mid āne sleġe besenċan oþþe ofslēan ("A whale could sink or kill me with one blow"). This case can be used without prepositions when the meaning is clear, as in ōðre naman, which means "[by] another name": Ūhtred sē Godlēasa æt Bebban byrġ, ōðre naman sē Deneslaga ("Uhtred the Godless of Bebbanburg, also known as the Daneslayer"). During the Old English period, the instrumental was falling out of use, having mostly merged with the dative. It was distinguished from the dative only in the masculine and neuter singular of strong adjectives and demonstratives, and even then the dative was often used instead.

Not all nouns take the same endings to inflect for number and case. Instead, each noun belongs to one of eight different classes, and each class has a different set of endings (sometimes several, depending on subtype).

In Proto-Germanic, one could tell which class a noun was by its ending in the nominative singular. But by the Old English period, most of these endings had disappeared or merged with other endings, so this was no longer possible.

A-stem nouns are by far the largest class, totaling 60% of all nouns.[8] Some are masculine, some are neuter. They're called a-stems because in Proto-Germanic times, they ended in -az (if masculine) or -ą (if neuter). However, in Old English, both these endings have vanished, and masculines only differ from neuters in the nominative/accusative plural.

Masculine a-stems are almost all inflected the same, as in hund ("dog") below. The neuter a-stems, however, are split in two: some of them end in -u in the nominative/accusative plural, while others have no ending there at all. This was caused by a sound change called high vowel apocope, which occurred in the prehistory of Old English. Short -i and -u disappeared at the ends of words after a heavy syllable—that is, a syllable containing a long vowel or long diphthong or ending in two or more consonants—and after two light syllables.[9] Nouns which kept short -i/-u are called light, while nouns which lost them are called heavy.

So, the a-stems actually come in three separate declensions: one for masculine nouns, one for "heavy" neuter nouns, and one for "light" neuter nouns. They are exemplified by hund ("dog"), sċip ("boat"), and hūs ("house"):

The ō-stems are by far the largest class after a-stems. They include the vast majority of feminine nouns, and zero nouns of any other gender.

They're called ō-stems because they ended in -ō in Proto-Germanic, but in Old English that ending has changed to -u or vanished. In the nominative singular, "light" ō-stems end in -u while "heavy" ō-stems have no ending, just like neuter a-stems in the nominative/accusative plural.

N-stems can be any gender, though there are only a few neuters: ēage ("eye"), ēare ("ear"), wange ("cheek"), and compounds ending in them, such as þunwange ("temple [of the head]"). N-stems are also called "weak nouns," because they are "weakly" inflected; i.e., most of their inflections have the same ending, -an. All other nouns are called "strong nouns."

Masculine and feminine n-stems are inflected the same except in the nominative singular, where masculines end in -a, feminines in -e:

The few neuter n-stems are declined the same as feminines, except they also have -e in the accusative singular:

The i-stems are so called because they ended in -iz in Proto-Germanic, but in Old English that ending has either become -e (in light i-stems) or vanished (in heavy i-stems). These nouns come in every gender, though neuter i-stems are rare.

By the earliest Old English prose, this class has already largely merged with other classes: masculine and neuter i-stems have taken on the same declension as a-stems, and feminine i-stems have almost the same declension as ō-stems. So, they're really only called i-stems because of their history, not because of how they inflect.

Their only distinct inflection survives in the accusative singular of feminine heavy i-stems, which fluctuates between -e (the ō-stem ending) and no ending (the inherited ending):

The exceptions are a few nouns that only come in the plural, namely lēode ("people") and various names of nationalities, such as Engle ("the English") and Dene ("the Danes"). These nouns kept the nominative/accusative plural -e that they inherited through regular sound change.

The u-stems are all masculine or feminine. They're all declined the same way, regardless of gender:

Pure u-stem nouns aren't very many, but some are very common: duru ("door"), medu ("mead"), wudu ("wood"). Most historical u-stems have been transferred over to the a-stems. Some nouns follow the a-stem inflection overall, but have a few leftover u-stem forms in their inflection. These forms may exist alongside regular a-stem forms:

• feld: dative singular felda
• ford: dative singular forda
• winter: dative singular wintra
• æppel: nominative/accusative plural æppla

Root nouns are a small class of nouns which, in Proto-Germanic, had ended in a consonant without any intervening vowel.

These nouns undergo i-umlaut in the dative singular and the nominative/accusative plural. This is the source of nouns in Modern English which form their plural by changing a vowel, as in man ~ men, foot ~ feet, tooth ~ teeth, mouse ~ mice, goose ~ geese, and louse ~ lice. In Old English, there were many more such words, including bōc ("book"), cū ("cow"), gāt ("goat"), āc ("oak"), hnutu ("nut"), burg ("city"), and sulh ("plow").

All root nouns are either masculine or feminine. Masculine root nouns are all heavy, but among feminines there is a contrast between light nouns and heavy nouns: light nouns end in -e where they have umlaut of the root vowel, while heavy nouns have no ending. The typical declension is this:

Nd-stems are nouns formed with the suffix -end, which creates agent nouns from verbs: āgan ("to own") → āgend ("owner"). All are masculine.

Single-syllable nd-stems are only possible when the stem ends in a vowel, which is rare; hence, only three are attested: frēond ("friend") ← frēoġan ("to love"), fēond ("enemy") ← fēoġan ("to hate"), and tēond ("accuser") ← tēon ("to accuse"). They're declined just like masculine root nouns:

The multi-syllable nd-stems are declined very differently. Their stem vowel never undergoes i-umlaut, and in fact, they're inflected just like a-stems in the singular. Moreover, their plural forms are truly unique: the genitive plural always ends in -ra, which is normally used for adjectives, and the nominative/accusative plural varies between no ending, the adjective ending -e, and the a-stem ending -as. The adjectival endings are a relic of the nd-stems' origin as present participles.

The r-stems total only five nouns: fæder, mōdor, brōðor, sweostor, and dohtor.

Brōðor, mōdor, and dohtor are all inflected the same, with i-umlaut in the dative singular. Sweostor is inflected the same except without i-umlaut. Fæder is indeclinable in the singular like sweostor, but has taken its nominative/accusative plural from the a-stems. In addition, brōðor and sweostor often take the prefix ġe- in the plural, while the rest never do.

Z-stems are the name given to four neuter nouns which inflect like light a-stems, except the plural endings begin with -r-. These nouns are ċild ("child"), ǣġ ("egg"), lamb ("lamb"), and ċealf ("calf").

The above only mentions the most common ways each noun class is inflected. There are many variations even within classes, some of which include:

• High vowel apocope (loss of short -i and -u at the end of a word) isn't entirely consistent. At first, these sounds were lost after a heavy syllable or two light syllables. But then, at some point before the written period, speakers started re-adding -u to the plurals of some neuter nouns where it had originally vanished. These nouns have two competing plurals, one with -u and one without it. So, "dreams" is either swefn or swefnu, "sails" is either seġl or seġlu, and "waters" is either wæter or wætru, among many other examples. Note that this mainly happened to a very specific set of nouns: those whose inflectional endings are preceded by a consonant plus /n/, /l/, or /r/.

• Some nouns have -u after a heavy syllable because, when high vowel apocope occurred, they had an intervening light syllable which later disappeared. Examples include nouns with the suffix -þu such as strengðu ("strength") and iermðu ("poverty"), z-stem plurals such as ǣġru ("eggs") and ċealfru ("calves"), and the a-stem plurals hēafdu ("heads") and dēoflu ("demons"). Also the plurals of all neuter a-stems that end in -e: wīte ("punishment"), pl. wītu; ǣrende ("message"), pl. ǣrendu.

• Some ō-stems unexpectedly end in -u in the singular, such as þīestru ("darkness"), hǣtu ("heat"), meniġu ("crowd"), ieldu ("age"), and bieldu ("bravery"). These nouns once belonged to a separate class called the īn-stems, which all ended in -ī. Then they merged with the ō-stems when this ending was replaced with -u—well after high vowel apocope had gone to completion, so the -u remained.

• Many nouns which end with an unstressed vowel plus a single consonant lose the unstressed vowel when they take inflectional endings: gristel ("cartilage"), gristles ("of cartilage"). However, it's impossible to predict which nouns this happens to without knowing the history of the word. For example, Dryhten ("the Lord") loses its unstressed -e- when inflected, but nīeten ("animal") does not; ēðel ("homeland") does, but crypel ("cripple") does not.[10]

• If an a-stem ends in one consonant and its stem vowel is short /æ/, it becomes /ɑ/ in the plural. "Day" is dæġ but "days" is dagas, "bath" is bæþ but "baths" is baðu. Other examples include fæt ("container"), sċræf ("cave"), stæf ("staff"), pæþ ("path"), hwæl ("whale"), and blæd ("blade").

• A-stems which end in ġ, ċ, or sċ after a vowel have hard g, c, or sc in the plural: fisċ /fiʃ/ ("fish"), pl. fiscas /ˈfiskɑs/. Other examples include dæġ ("day"), weġ ("way"), twiġ ("twig"), disċ ("plate"), dīċ ("ditch"), līċ ("corpse"), and wīċ ("village").

• If a noun ends in h, the h disappears before inflectional endings. This lengthens the preceding vowel or diphthong (if it's short). Unless the h comes right after a consonant, it also deletes the following vowel, except in the genitive plural, where an -n- has been inserted to prevent this from happening. All this is exemplified by two masculine a-stems, sċōh and fearh:

• If an a-stem ends in -u, the u is replaced with w before inflectional endings: searu ("machine"), dat. sg. searwe.

• Something similar happens with a subgroup of ō-stem nouns called the wō-stems. These nouns once ended in -wu, before a sound change occurred which caused the w to disappear in the nominative singular; subsequently some also lost the -u by high vowel apocope. By the written period, they are indistinguishable from other ō-stems in the nominative singular, except they keep the w before inflectional endings. These nouns include sċadu ("shadow/shade"), sinu ("sinew"), mǣd ("meadow"), and lǣs ("pasture").

There are two separate sets of inflections, traditionally called the "strong declension" and the "weak declension." Together, both declensions contain many different inflections, though just ten or eleven unique forms typically cover all of them. The usual endings are exhibited by cwic ("alive") among many other adjectives:

In general, the weak declension is used after the words for "the/that" and "this," nouns in the genitive case, and possessive determiners such as "my," "your," and "his," while the strong declension is used the rest of the time. Hence "a live scorpion" is cwic þrōwend, while "the live scorpion" is sē cwica þrōwend. Further details:

• The weak declension is also used in direct address, as in Ēalā fæġre mæġden ("Hey beautiful girl") or þū stunte hōre ("you stupid whore").

• Ordinal numbers and comparative adjectives only take the weak declension, even in situations that would otherwise call for the strong declension. The most important exception is ōðer ("other/second"), which is always strong despite being both an ordinal number and a comparative. Of the four words for "first," forma and ǣrra are always weak, but ǣrest and fyrest can be either strong or weak just like most other adjectives.

• The adjective āgen ("own") is usually strong in the phrase "one's own": Hēo forlēt ōðre dæġe on hire āgnum horse ("She left the next day on her own horse").

Adjectives once came in many different classes just like nouns, but by Old English times, all adjectives have basically the same endings as cwic above. However, there are still a good number of differences and irregularities:

• As with nouns, there are "light" adjectives which retain the inflectional ending -u (which occurs in the feminine nominative singular and neuter nominative/accusative plural), and "heavy" adjectives which have lost it. Originally -u disappeared after a heavy syllable or two light syllables, but speakers have re-added it to some adjectives where it had been lost. Namely, those with the suffixes -iġ or -līċ: bisigu sweord ("busy swords" [nom. pl. neut.]), broðorlīcu lufu ("brotherly love" [nom. sg. fem.]).[11][10]

• Some adjectives have -u after a heavy syllable because, when high vowel apocope occurred, they had an intervening light syllable which later disappeared. Examples include lȳtel ("little"), nom. sg. fem./nom-acc. pl. neut lȳtlu; ōðer ("other"), nom. sg. fem./nom-acc. pl. neut ōðru; and ēower ("your"), nom. sg. fem./nom-acc. pl. neut. ēowru.

• Adjectives ending in -e all lose the -e before inflectional endings: blīðe ("happy"), nom. sg. masc. blīðne. They also all retain -u: blīðu ċildru ("happy children").[12]

• If an adjective ends in short æ plus a single consonant, the æ becomes a before endings beginning with a vowel: glæd ("glad"), nom. pl. masc. glade.

• If an adjective ends in h, the h disappears before inflectional endings. This lengthens the preceding vowel or diphthong: þweorh ("crooked"), þwēorre gen. sg. fem. Also, if the h comes right after a vowel, any immediately following vowel disappears: hēah ("high"), acc. sg. masc. hēane, dat. sg. masc. hēam, nom. pl. masc. hēa.

• If an adjective ends in -u, it changes to o before an inflectional ending beginning with a consonant: ġearu ("ready"), acc. sg. masc. ġearone, dat. sg. fem. ġearore. Before a vowel, it changes to w: nom. pl. masc. ġearwe.

• Most adjectives ending in ġ, ċ, or sċ have hard g, c, or sc before an ending beginning with a back vowel (/ɑ/, /o/, /u/). Ġesċādlīċ ("rational"), nom. pl. fem. ġesċādlīca; mennisċ ("human"), dat. sg. neut. menniscum.

• Many adjectives which end in an unstressed vowel plus a single consonant lose the unstressed vowel before endings beginning with vowels: lȳtel ("little"), nom. pl. fem. lȳtla.

Old English never uses the equivalents of "more" and "most" to form comparative or superlative adjectives. Instead, the equivalents of "-er" and "-est" are used (-ra and -ost, for some words -est). "More beautiful" is fæġerra, literally "beautiful-er," and "most beautiful" is fæġrost, literally "beautiful-est." [lower-alpha 1] Other examples include beorht ("bright") → beorhtra ("brighter"), beorhtost ("brightest"); bearnēacen ("pregnant") → bearnēacenra ("more pregnant"), bearnēacnost ("most pregnant"); and cnihtlīċ ("boyish") → cnihtlīcra ("more boyish"), cnihtlīcost ("most boyish").

A handful of words form the comparative and superlative with i-umlaut, namely eald ("old") → ieldra, ieldest; ġeong ("young") → ġingra, ġinġest; strang ("strong") → strengra, strenġest; lang ("long") → lengra, lenġest; sċort ("short") → sċyrtra, sċyrtest; and hēah ("high") → hīera, hīehst.

A few more become totally different words: gōd ("good") → betera, betst; yfel ("bad") → wiersa, wierrest; miċel ("much/a lot/big") → māra ("more/bigger"), mǣst ("most/biggest"); lȳtel ("little") → lǣssa ("less/smaller"), lǣsest ("least/smallest").

Hwā ("who") and hwæt ("what") follow natural gender, not grammatical gender: as in Modern English, hwā is used with people, hwæt with things. However, that distinction only matters in the nominative and accusative cases, because in every other case they're identical:

Hwelċ ("which" or "what kind of") is inflected like an adjective. Same with hwæðer, which also means "which" but is only used between two alternatives:

The first- and second-person pronouns are the same for all genders. They also have special dual forms, which are only used for groups of two things, as in "we both" and "you two." The dual forms are common, but the ordinary plural forms can always be used instead when the meaning is clear.

Many of the forms above bear a strong resemblance to the Modern English words they eventually became. For instance, in the genitive case, ēower became "your," ūre became "our," and mīn became "my." However, the plural third-person personal pronouns were all replaced with Old Norse forms during the Middle English period, yielding "they," "them," and "their."

Strong verbs use a Germanic form of conjugation known as ablaut. They form the past tense by changing their stem vowel. These verbs still exist in modern English, where they're often called "irregular verbs": for example sing, sang, sung is a strong verb, as are swim, swam, swum and break, broke, broken.

Strong verbs have been growing less and less common over the centuries, because their conjugations are more complicated than weak verbs and harder to predict. That means many verbs that were strong in Old English times are now weak. These include walk, sleep, help, laugh, step, sneeze, chew, wash, shine, climb, let, bake, lock, read, drag, bark, sweep, float, bow, row, fart, creep, flow, starve, weep, grip, leap, mow, slay, shove, carve, gnaw, braid, flee, fare, ban, wreak, quell, delve, abide, yield, spurn, thresh, swell, milk, suck, burst, load, melt, and swallow. Two of these even became weak during the Old English period: sleep (slǣpan) and read (rǣdan).

Also, by Old English times, people had long since stopped coining new strong verbs. Even today, almost every strong verb in the modern language dates back to before Old English, even to before Proto-Germanic.

Most strong verbs are not considered irregular in Old English, because each belongs to one of seven major classes, each with its own pattern of stem changes. Learning these is often a challenge for students of the language, though English speakers may see connections between the old verb classes and their modern forms.

The classes had the following distinguishing features to their infinitive stems, each corresponding to particular stem changes within their strong-conjugating paradigms:

The first past stem is used in the past, for the first- and third-person singular. The second past stem is used for second-person singular, and all persons in the plural (as well as the preterite subjunctive). Strong verbs also exhibit i-mutation of the stem in the second- and third-person singular in the present tense.

The third class went through so many sound changes that it was barely recognisable as a single class. The first was a process called 'breaking'. Before ⟨h⟩, and ⟨r⟩ + another consonant, ⟨æ⟩ turned into ⟨ea⟩, and ⟨e⟩ to ⟨eo⟩. Also, before ⟨l⟩ + another consonant, the same happened to ⟨æ⟩, but ⟨e⟩ remained unchanged (except before combination ⟨lh⟩).

A second sound change turned ⟨e⟩ to ⟨i⟩, ⟨æ⟩ to ⟨a⟩, and ⟨o⟩ to ⟨u⟩ before nasals.

Altogether, this split the third class into four sub-classes:

Regular strong verbs were all conjugated roughly the same, with the main differences being in the stem vowel. Thus stelan "to steal" represents the strong verb conjugation paradigm.

Weak verbs form the past tense by adding endings with -d- in them (sometimes -t-) to the stem. In Modern English, these endings have merged as -ed, forming the past tense for most verbs, such as love, loved and look, looked.

Weak verbs already make up the vast majority of verbs in Old English. There are two major types: class I and class II. A class III also existed, but contained only four verbs.

By the Old English period, new class I weak verbs had stopped being produced, but so many had been coined in Proto-Germanic that they were still by far the most common kind of verb in Old English.[17] These verbs are often recognizable because they feature i-umlaut of the word they were derived from, as in dēman ("to judge") from dōm ("judgment"), blǣċan ("to bleach") from blāc ("pale"), tellan ("to count") from tæl ("number"), and rȳman ("to make room") from rūm ("room"). They are also the source of alterations in Modern English such as feed ~ food, fill ~ full, and breed ~ brood.

Class I weak verbs are not all conjugated the same. Their exact endings depend on a complex combination of factors, mostly involving the length of the stem vowel and which consonants the stem ends in, and sometimes also the history of the word. But the largest number are conjugated the same as dǣlan ("to share"):

Many verbs ending in a double consonant are conjugated like temman ("to tame"), with the same endings and the same alternation between single and double consonants:

Class I weak verbs that end in -rian are conjugated like styrian ("to move"):

Class II weak verbs are easily recognized by the fact that nearly all of them end in -ian: hopian ("to hope"), wincian ("to wink"), wandrian ("to wander").

By the Old English period, this was the only productive verb class left. Newly created verbs were almost automatically weak class II.[18]

Unlike weak class I, they never cause i-umlaut, so their stems are usually identical to the stem of the word they were derived from: lufu ("love") → lufian ("to love"), mynet ("coin") → mynetian ("to coin"), hwelp ("puppy") → hwelpian ("[of animals] to give birth").

Their conjugation is also much simpler than all other verb classes. Almost all weak class II verbs have precisely the same endings, completely unaffected by the makeup of the stem or the history of the word. A typical example is lufian ("to love"):

Though it was once much larger, containing many verbs which later became class II, only four verbs still belonged to this group by the period of written texts: habban ("to have"), libban ("to live") seċġan ("to say"), and hyċġan "to think." Each of these verbs is distinctly irregular, though they share some commonalities.

The preterite-presents are verbs whose present tenses look like the past tenses of strong verbs. This resemblance isn't an accident: they descend from old Proto-Indo-European stative verbs, which normally developed into the past tense of the Germanic languages. The preterite-present verbs are an exception to this development, remaining as independent verbs. For example, the first-person present of witan ("to know") originally meant "I have seen", referring to the state of having seen, and by implication "I know". At some point well before Old English, these verbs were given their own past tenses by tacking on weak past endings, but without an intervening vowel. This lack of an intervening vowel then led to alternations in the consonants, and sometimes vowels as well.

There are only a dozen preterite-presents, but most are among the most frequent verbs in the language. They are magan ("can"), sċulan ("should/must/to owe"), mōtan ("may"), þurfan ("to need"), witan" ("to know"), cunnan" ("to know/know how"), ġemunan ("to remember"), durran ("to dare"), āgan ("to own"), dugan ("to be useful"), ġenugan ("to suffice"), and unnan ("to grant").

In spite of heavy irregularities, these can be grouped into four groups of similarly conjugated verbs:

1. Āgan, durran, mōtan, and witan
2. Cunnan, ġemunan (outside the past tense), and unnan
3. Dugan, magan, and ġenugan
4. Sċulan and þurfan

Additionally, there is a further group of four verbs which are anomalous: "want", "do", "go" and "be". These four have their own conjugation schemes which differ significantly from all the other classes of verb. This is not especially unusual: "want", "do", "go", and "be" are the most commonly used verbs in the language, and are very important to the meaning of the sentences in which they are used. Idiosyncratic patterns of inflection are much more common with important items of vocabulary than with rarely used ones.

Dōn 'to do' and gān 'to go' are conjugated alike; willan 'to want' is similar outside of the present tense.

The verb 'to be' is actually composed of three different stems: one beginning with w-, one beginning with b-, and one beginning with s-. These are traditionally thought of as forming two separate words: wesan, comprising the forms beginning with w- and s-, and bēon, comprising the forms beginning with b-.

In the present tense, wesan and bēon carried a difference in meaning. Wesan was used in most circumstances, whereas bēon was used for the future and for certain kinds of general statements.

There was some flexibility in word order of Old English since the heavily inflected nature of nouns, adjectives, and verbs often indicated the relationships between clause arguments. Scrambling of constituents was common. Even sometimes scrambling within a constituent occurred, as in Beowulf line 708 wrāþum on andan:

Something similar occurs in line 713 in sele þām hēan "in the high hall" (lit. "in hall the high").

Extraposition of constituents out of larger constituents is common even in prose, as in the well-known tale of Cynewulf and Cyneheard, which begins

Hēr Cynewulf benam Sigebryht his rīces ond westseaxna wiotan for unryhtum dǣdum, būton Hamtūnscīre; ...

(Literally) "Here Cynewulf deprived Sigebryht of his kingdom and West Saxons' counselors for unright deeds, except Hampshire"

(translated) "Here Cynewulf and the West Saxon counselors deprived Sigebryht of his kingdom, other than Hampshire, for unjust actions"

The words ond westseaxna wiotan "and the West Saxon counselors" (lit. "and (the) counselors of (the) West Saxons") have been extraposed from (moved out of) the compound subject they belong in, in a way that would be impossible in modern English. In Old English, case inflection preserves the meaning: the verb beniman "to deprive" (appearing in this sentence in the form benam, "[he] deprived") needs a word in the genitive case to show what someone or something is deprived of, which in this sentence is rīces "of kingdom" (nominative rīce, "kingdom"), whereas wiotan "counselors" is in the nominative case and therefore serves a different role entirely (the genitive of it would be wiotana, "of counselors"); for this reason the interpretation that Cynewulf deprived Sigebryht of the West Saxon counselors was not possible for speakers of Old English. The Old English sentence still isn't in theory perfectly unambiguous, as it contains one more word in the genitive: westseaxna ("of West Saxons", nominative westseaxan "West Saxons"), and the form wiotan "counselors" may also represent the accusative case in addition to the nominative, thus for example creating the grammatical possibility of the interpretation that Cynewulf also took the West Saxons away from the counselors, but this would have been difficult to conceive.

Main clauses in Old English tend to have a verb-second (V2) order, where the finite verb is the second constituent in a sentence, regardless of what comes first. There are echoes of this in modern English: "Hardly did he arrive when ...", "Never can it be said that ...", "Over went the boat", "Ever onward marched the weary soldiers ...", "Then came a loud sound from the sky above". In Old English, however, it was much more extensive, like the word order in modern Germanic languages other than modern English. If the subject appears first, there is an SVO order, but it can also yield orders such as OVS and others. In questions VSO was common, see below.

In subordinate clauses, however, the word order is markedly different, with verb-final constructions the norm, again as in Dutch and German. Furthermore, in poetry, all the rules were frequently broken. In Beowulf, for example, main clauses frequently have verb-initial or verb-final order, and subordinate clauses often have verb-second order. (However, in clauses introduced by þā, which can mean either "when" or "then", and where word order is crucial for telling the difference, the normal word order is nearly always followed.)

Those linguists who work within the Chomskyan transformational grammar paradigm often believe that it is more accurate to describe Old English (and other Germanic languages with the same word-order patterns like modern German) as having underlying subject-object-verb (SOV) ordering. According to this theory, all sentences are initially generated using this order, but in main clauses, the verb is moved back to the V2 position (technically, the verb undergoes V-to-T raising). That is said to explain the fact that Old English allows inversion of subject and verb as a general strategy for forming questions, while modern English uses this strategy almost only with auxiliary verbs and the main verb "to be", requiring do-support in other cases.

Most of the time the word order of Old English changed when asking a question, from SVO to VSO. While many purport that Old English had free word order, this is not quite true, as there were conventions for the positioning of subject, object and verb in clause.

"I am..." becomes "Am I..."

"Ic eom..." becomes "Eom ic..."

Old English did not use forms equivalent to "who, when, where" in relative clauses (as in "The man whom I saw") or subordinate clauses ("When I got home, I went to sleep").

Instead, relative clauses used one of the following:

1. An invariable complementizer þe
2. The demonstrative pronoun se, sēo, þæt
3. The combination of the two, as in se þe

Subordinate clauses tended to use correlative conjunctions, e.g.

Þā ic hām ēode, þā slēp ic.

(word-for-word) "Then I home went, then slept I."

(translated) "When I went home, I slept."

The word order usually distinguished the subordinate clause (with verb-final order) from the main clause (with verb-second word order).

The equivalents of "who, when, where" were used only as interrogative pronouns and indefinite pronouns, as in Ancient Greek and Sanskrit.

Besides þā ... þā ..., other correlative conjunctions occurred, often in pairs of identical words, e.g.:

• þǣr X, þǣr Y: "Where X, Y"
• þanon X, þanon Y: "Whence (from where/wherefrom) X, Y"
• þider X, þider Y: "Whither (to where/whereto) X, Y"
• þēah (þe) X, þēah Y: "Although X, Y"
• þenden X, þenden Y: "While X, Y"
• þonne X, þonne Y: "Whenever X, Y"
• þæs X, þæs Y: "As/after/since X, Y"
• þȳ X, þȳ Y: "The more X, the more Y"
