Navajo grammar

The prefixes that occur on a Navajo verb are added in specified more or less rigid order according to prefix type. This type of morphology is called a position class template (or slot-and-filler template). Below is a table of a recent proposal of the Navajo verb template (Young & Morgan 1987). Edward Sapir and Harry Hoijer were the first to propose an analysis of this type. A given verb does not have a prefix for every position. In fact, most Navajo verbs are not as complex as the template might suggest: the maximum number of prefixes is around eight.

The Navajo verb is composed of a verb stem and a set of prefixes. The prefixes can be divided into a conjunct prefix set and disjunct prefix set. The disjunct prefixes occur on the outer left edge of the verb. The conjunct prefixes occur after the disjunct prefixes, closer to the verb stem. Two types of prefixes can be distinguished by their different phonological behavior.

The prefix complex may be subdivided into 11 positions, with some of the positions having even further subdivisions:

Although prefixes are generally found in a specific position, some prefixes change order by the process of metathesis. For example, prefix ʼa- (3i object pronoun) usually occurs before di-, as in

ʼadisbąąs "I'm starting to drive some kind of wheeled vehicle along" [ ← ʼa- + di- + sh- + ł + -bąąs].

However, when ʼa- occurs with the prefixes di- and ni-, the ʼa- metathesizes with di-, leading to an order of di- + ʼa- + ni-, as in

diʼnisbąąs "I'm in the act of driving some vehicle (into something) & getting stuck" [ ← di-ʼa-ni-sh-ł-bąąs ← ʼa- + di- + ni- + sh- + ł + -bąąs]

instead of the expected ʼadinisbąąs (ʼa-di-ni-sh-ł-bąąs) (ʼa- is reduced to ʼ-).

Although the verb template model of analysis has been traditionally used to describe the Navajo verb, other analyses have been proposed by Athabascanists.

Navajo verbs have pronominal (i.e. pronoun) prefixes that mark both subjects and objects. The prefixes can vary in certain modes, particularly the perfective mode (See Mode and Aspect section below for a discussion of modes). The prefixes are inflected according to person and number. The basic subject prefixes (and their abbreviations as used by Young & Morgan) are listed in the table below:

Number	Subject prefixes		Object prefixes
	Singular	Dual-plural	Singular	Dual-plural
First (1)	-sh-	-Vd-	shi-	nihi-
Second (2)	ni-	-oh-	ni-
Third (3)	-Ø-		bi-
Third (3o)			yi-
Fourth (3a)	ji-		ha- ~ ho-
Indefinite (3i)	ʼa-		ʼa-
Space (3s)	ha- ~ ho-		ha- ~ ho-
Reflexive	–		(ʼá)-di-
Reciprocal	–		ʼahi-

The subject prefixes occur in two different positions. The first and second subject prefixes (-sh-, -Vd-, ni-, -oh-) occur in position 8 directly before the classifier prefixes. The fourth, indefinite, and "space" subject prefixes (ji-, ʼa-, ha-~ho-) are known as "deictic subject pronouns" and occur in position 5. The third person subject is marked by the absence of a prefix, which is usually indicated with a zero prefix -Ø- in position 8. The object prefixes can occur in position 4 as direct objects, in position 1a as "null postpositions", or in position 0 as the object of postpositions that have been incorporated into the verb complex.

The fourth person subject prefix ji- is a kind of obviative third person. It refers primarily to persons or personified animals (unlike the regular third person). It has a number of uses including:

• referring to the main character in narratives
• distinguishing between two third person referents
• referring politely or impersonally to certain socially-distant individuals (e.g. when speaking to opposite-sex siblings and relatives through marriage, giving admonitions, speaking of the dead)

When used as an impersonal, it may be translated into English as "one" as in béésh bee njinéego hálaʼ da jiigish "one can cut one's hand playing with knives". The "space" prefix can be translated as "area, place, space, impersonal it" as in halgai "the area/place is white" and nahałtin "it is raining". The prefix has two forms: ha- and ho- with ho- having derived forms such as hw- and hwi-.

An example paradigm for "to freeze" (imperfective mode) showing the subject prefixes:

	Singular		Dual-Plural
First	yishtin	"I freeze"	yiitin	"we (2+) freeze"
Second	nitin	"you freeze"	wohtin	"you (2+) freeze"
Third	yitin "he/she/it/they freeze"
Fourth (3a)	jitin "he/she/they freeze"
Indefinite (3i)	atin "someone/something freezes"

The "classifiers" are prefixes of position 9 (the closest to the verb stem) that affect the transitivity of the verb, in that they are valence and voice markers. Calling them "classifiers" is a misnomer, however, as they do not classify anything and are not related to the classificatory verb stems (which actually do classify nouns, see classificatory verbs below). There are four classifiers: -Ø-, -ł-, -d-, -l-. The -Ø- classifier is the absence of a prefix, which is usually indicated by a null morpheme.

The -ł- classifier is a causative-transitivizing prefix of active verbs. It often can transitivize an intransitive -Ø- verb: yibéézh "it's boiling" (yi-Ø-béézh), yiłbéézh "he's boiling it (yi-ł-béézh); naʼniyęęsh "somethings flows about in a meandering fashion" (naʼni-Ø-yęęsh), naʼniłhęęsh "he's making it flow about in a meandering fashion" (naʼni-ł-yęęsh).

The -d- classifier occurs in most passive, mediopassive, reflexive, and reciprocal verbs that are derived from verbs with a -Ø- classifier: yizéés "he's singeing it" (yi-Ø-zéés), yidéés "it's being singed" (yi-d-zéés).

The -l- occurs in most passive, mediopassive, reflexive, and reciprocal verbs that are derived from verbs with a -ł- classifier: néíłtsááh "he's drying it" (ná-yi-ł-tsááh), náltsááh it's being dried" (ná-l-tsááh).

Some verbs can occur with all four classifier prefixes:

• siʼą́ "roundish object lies in position" (-Ø-ʼą́)
• haatʼą́ "roundish object was taken up & out (i.e. extracted)" (-d-ʼą́)
• séłʼą́ "I keep a roundish object in position" (-ł-ʼą́)
• néshʼą́ "I have my head in position" (-l-ʼą́)

In other verbs, the classifiers do not mark transitivity and are considered thematic prefixes that simply are required to occur with certain verb stems.

Navajo has the following verb modes:[2]

• Imperfective (describes an action/event that began but is seen as incomplete)
• Perfective (describes an action/event that began and is seen as complete)
• Progressive (describes an action/event that is ongoing)
• Future
• Usitative (describes an action/event that happens customarily but not always)
• Iterative (describes an action/event that happens repeatedly)
• Optative (describes a potential action/event in terms of the speaker’s wishes)

The modes above may have up to five distinct verb stem forms. The progressive and future modes share the same stem form as do the usitative and iterative modes. The optative mode usually has the same verb stem as the imperfective mode, although for some verbs the stem forms differ (in the example "to play, tease" above, the perfective and the optative stems are the same). For example, the verb meaning "to play, tease" has the following five stem forms for the seven modes:

The imperfective indicates an event/action that has begun but remains incomplete. Although this mode does not refer to tense, it can usually be translated into English as a present tense form: yishááh "I'm (in the act of) going/coming", yishą́ "I'm (in the act of) eating (something)". With the addition of adverbials, the imperfective can be used for events/actions in the past, present, or future. The mode is used in the second person for immediate imperatives. The imperfective mode has a distinct imperfective stem form and four different mode-aspect prefix paradigms: (1) with a ni- terminative prefix in position 7 as in nishááh "I'm in the act of arriving", (2) with a si- stative prefix in position 7 as in shishʼaah "I'm in the act of placing a SRO" in dah shishʼaah "I'm in the act of placing a SRO up" (dah "up"), (3) with no prefix in position 7, usually identified as a Ø- prefix, as in yishcha "I'm crying", (4) with either a yi- transitional or yi- semelfactive prefix in position 6 (and no prefix in position 7).

The perfective indicates an event/action that has been completed. When referring to past situations, it usually corresponds to English simple past: yíyáʼ "I went/came/arrived", yíyą́ą́ʼ "I ate (something)". However, since the perfective mode is not a tense, it can be used to refer non-past actions, such as the future (where it may be translated as English "will have" + VERB). The perfective mode has a distinct perfective stem form and four different prefix paradigms: (1) with a yí- perfective prefix with a high tone in position 7 as in yíchʼid "I scratched it", (2) with a ní- terminative prefix with a high tone in position 7 as in níyá "I arrived", (3) with a sí- stative prefix with high tone in position 7 as in sélį́į́ʼ "I roasted it", (4) with a yi- transitional prefix in position 6 (and Ø- in position 7) as in yiizįʼ "I stood up".

The progressive indicates an incomplete event/action that is ongoing without reference to the beginning or end of the event/action. This mode may be translated into English as BE + VERB-ing + "along": yishááł "I'm going/walking along", yishtééł "I'm carrying it along".

The future mode is primarily a future tense — indicating a prospective event/action: deeshááł "I'll go/come", deeshį́į́ł "I'll eat (something)". The progressive mode has a yi- progressive prefix (in position 7), the future has a di- inceptive prefix (in position 6) and the yi- progressive prefix.

The usitative indicates a repetitive event/action that takes place customarily: yishááh "I usually go", yishdlį́į́h "I always drink (something)". The iterative is a frequentative indicating a recurrent event/action that takes place repeatedly and customarily: chʼínáshdááh "repeatedly go out" as in ahbínígo tłʼóóʼgóó chʼínáshdááh "I always (repeatedly) go outdoors in the morning" (ahbínígo "in the morning", tłʼóóʼgóó "outdoors"), náshdlį́į́h "drink (something) repeatedly" as in nínádiishʼnahgo gohwééh náshdlį́į́h "I drink coffee when I get up" (nínádiishʼnahgo "when I get up", gohwééh "coffee"). The iterative is distinguished from the usitative by a ná- repetitive prefix (in position 2) and also sometimes by a -d- or -ł- classifier prefix (in position 9).

The optative indicates a positive or negative desire or wish. The mode is used with the addition of adverbial particles that follow the verb, such as laanaa and lágo: nahółtą́ą́ʼ laanaa "I wish it would rain", nahółtą́ą́ʼ lágo "I hope it doesn't rain". With punctual verbs, the optative mode can be used to form a negative imperative: shinóółʼį́į́ʼ (lágo) "don't look at me!". In certain adverbial frames, the optative indicates positive or negative potential.

The Primary aspects:

• Momentaneous - punctually (takes place point in time)
• Continuative - indefinite span of time & movement with specified direction
• Durative - indefinite span of time, non-locomotive uninterrupted continuum
• Repetitive - continuum of repeated acts or connected series of acts
• Conclusive - like durative but in perfective terminates with static sequel
• Semelfactive - single act in repetitive series of acts
• Distributive - distributive manipulation of objects or performance of actions
• Diversative - movement distributed among things (similar to distributive)
• Reversative - result in directional change
• Conative - attempted action
• Transitional - shift from one state to another
• Cursive - progression in a line through time/space (only progressive mode)

The subaspects:

• Completive - event/action simply takes place
• Terminative - stopping of action
• Stative - sequentially durative and static
• Inceptive - beginning of action
• Terminal - inherently terminal action
• Prolongative - arrested beginning or ending of action
• Seriative - interconnected series of successive separate & distinct acts
• Inchoative - focus on beginning of non-locomotion action
• Reversionary - return to previous state/location
• Semeliterative - single repetition of event/action

Navajo modes co-occur with various aspects. For example, the verb "rain falls" can occur in the perfective mode with the momentaneous and distributive aspects: -tsąąʼ (perfective momentaneous), -tsįʼ (perfective distributive). As with the modes, different aspects have different stem forms even when in the same mode, as seen with the previous "rain falls" perfective stems. Thus, a given verb has a set of stem forms that can be classified into both a mode and an aspect category. Verb stem paradigms of mode and aspect are given below for two different verbs:

As can be seen above, some aspect and mode combinations do not occur depending mostly upon the semantics of the particular verb. Additionally, some aspects do not occur at all with a particular verb. The patterns of verb stem alternations are very complex although there is a significant amount of homophony. A particularly important investigation into this area of the Navajo verb is Hardy (1979).

Navajo has verb stems that classify a particular object by its shape or other physical characteristics in addition to describing the movement or state of the object. Athabaskan linguistics identifies these as classificatory verb stems and usually identifies them with an acronym label. The eleven primary classificatory "handling" verb stems appear listed below (in the perfective mode):

To compare with English, Navajo has no single verb that corresponds to the English word give. To say the equivalent of Give me some hay!, the Navajo verb níłjool (NCM) must be used, while for Give me a cigarette! the verb nítįįh (SSO) must be used. The English verb give is expressed by eleven different verbs in Navajo, depending on the characteristics of the given object.

In addition to defining the physical properties of the object, primary classificatory verb stems also can distinguish between the manner of movement of the object. The stems may then be grouped into three different categories:

1. handling
2. propelling
3. free flight

Handling includes actions such as carrying, lowering, and taking. Propelling includes tossing, dropping, and throwing. Free flight includes falling, and flying through space.

Using an example for the SRO category, Navajo has

1. -ʼą́ "to handle (a round object)",
2. -neʼ "to throw (a round object)", and
3. -l-tsʼid "(a round object) moves independently".

Like most Athabaskan languages, Southern Athabaskan languages show various levels of animacy in its grammar, with certain nouns taking specific verb forms according to their rank in this animacy hierarchy. For instance, Navajo nouns can be ranked by animacy on a continuum from most animate (a human or lightning) to least animate (an abstraction) (Young & Morgan 1987: 65-66):

humans/lightning → infants/big animals → midsize animals → small animals → insects → natural forces → inanimate objects/plants → abstractions

Generally, the most animate noun in a sentence must occur first while the noun with lesser animacy occurs second. If both nouns are equal in animacy, then either noun can occur in the first position. So, both example sentences (1) and (2) are correct. The yi- prefix on the verb indicates that the 1st noun is the subject and bi- indicates that the 2nd noun is the subject.

(1)

Ashkii

boy

atʼééd

girl

yiníłʼį́.

yi-look

Ashkii atʼééd yiníłʼį́.

boy girl yi-look

'The boy is looking at the girl.'

(2)

Atʼééd

girl

ashkii

boy

biníłʼį́.

bi-look

Atʼééd ashkii biníłʼį́.

girl boy bi-look

'The girl is being looked at by the boy.'

But example sentence (3) sounds wrong to most Navajo speakers because the less animate noun occurs before the more animate noun:

(3)

* Tsídii

bird

atʼééd

girl

yishtąsh.

yi-pecked

* Tsídii atʼééd yishtąsh.

bird girl yi-pecked

'The bird pecked the girl.'

To express this idea requires that the more animate noun occur first, as in sentence (4):

(4)

Atʼééd

girl

tsídii

bird

bishtąsh.

bi-pecked

Atʼééd tsídii bishtąsh.

girl bird bi-pecked

'The girl was pecked by the bird.'

Note that although sentence (2) and (4) are translated into English with a passive verb, in Navajo it is not passive. Passive verbs are formed by certain classifier prefixes (i.e., transitivity prefixes) that occur directly before the verb stem in position 9. The yi-/bi- prefixes do not mark sentences as active or passive, but as direct or inverse.

Possession in Navajo is expressed with personal pronoun prefixes:

	Singular	Dual	Plural
First	shi-	nihi-	danihi-
Second	ni-	nihi-	danihi-
Third	bi-
Fourth (3o)	yi-
Fourth (3a)	ha-, hw-
Indefinite (3i)	a-

Most of the time, these prefixes take a low tone, but in some nouns and postpositions, the final syllable of the prefix takes a high tone, such as shílaʼ "my hand," nihílaʼ "our/your hand."

The prefixes are also used when the possessor noun in a possessive phrase is a noun, as in Jáan bimá lit. "John his-mother," i.e., "John's mother."

Navajo marks inalienable possession for certain nouns — relatives, body parts, homes and dens. These nouns can only appear with a possessive prefix, as in shimá "my mother." If one wishes to speak of mothers in general, the 3rd person indefinite prefix ʼa- "someone's" is used, amá.
