Arabic alphabet

There are two main collating sequences for the Arabic alphabet: abjad and hija.

The original ʾabjadīy order (أَبْجَدِيّ), used for lettering, derives from the order of the Phoenician alphabet, and is therefore similar to the order of other Phoenician-derived alphabets, such as the Hebrew alphabet. In this order, letters are also used as numbers, Abjad numerals, and possess the same alphanumeric code/cipher as Hebrew gematria and Greek isopsephy.

The hijā’ī (هِجَائِي) or alifbāʾī (أَلِفْبَائِي) order, used where lists of names and words are sorted, as in phonebooks, classroom lists, and dictionaries, groups letters by similarity of shape.

The ʾabjadī order is not a simple historical continuation of the earlier north Semitic alphabetic order, since it has a position corresponding to the Aramaic letter samekh/semkat ס, yet no letter of the Arabic alphabet historically derives from that letter. Loss of sameḵ was compensated for by the split of shin ש into two independent Arabic letters, ش (shīn) and ﺱ (sīn) which moved up to take the place of sameḵ. The six other letters that do not correspond to any north Semitic letter are placed at the end.

This is commonly vocalized as follows:

ʾabjad hawwaz ḥuṭṭī kalaman saʿfaṣ qarashat thakhadh ḍaẓagh.

Another vocalization is:

ʾabujadin hawazin ḥuṭiya kalman saʿfaṣ qurishat thakhudh ḍaẓugh

This can be vocalized as:

ʾabujadin hawazin ḥuṭiya kalman ṣaʿfaḍ qurisat thakhudh ẓaghush

Modern dictionaries and other reference books do not use the abjadī order to sort alphabetically; instead, the newer hijāʾī order is used wherein letters are partially grouped together by similarity of shape. The hijāʾī order is never used as numerals.

Another kind of hijāʾī order was used widely in the Maghreb until recently when it was replaced by the Mashriqi order.[3]

The Arabic alphabet is always cursive and letters vary in shape depending on their position within a word. Letters can exhibit up to four distinct forms corresponding to an initial, medial (middle), final, or isolated position (IMFI). While some letters show considerable variations, others remain almost identical across all four positions. Generally, letters in the same word are linked together on both sides by short horizontal lines, but six letters (و ,ز ,ر ,ذ ,د ,ا) can only be linked to their preceding letter. For example, أرارات (Ararat) has only isolated forms because each letter cannot be connected to its following one. In addition, some letter combinations are written as ligatures (special shapes), notably lām-alif لا,[4] which is the only mandatory ligature (the un-ligated combination ل‍‌‍ا is considered difficult to read).

Notes

• See the article Romanization of Arabic for details on various transliteration schemes; however, Arabic language speakers may usually not follow a standardized scheme when transcribing names. Also names are regularly transcribed as pronounced locally, not as pronounced in Literary Arabic (if they were of Arabic origin).
• Regarding pronunciation, the phonemic values given are those of Modern Standard Arabic, which is taught in schools and universities. In practice, pronunciation may vary considerably from region to region. For more details concerning the pronunciation of Arabic, consult the articles Arabic phonology and varieties of Arabic.
• The names of the Arabic letters can be thought of as abstractions of an older version where they were meaningful words in the Proto-Semitic language. Names of Arabic letters may have quite different names popularly.
• Six letters (و ز ر ذ د ا) do not have a distinct medial form and have to be written with their final form without being connected to the next letter. Their initial form matches the isolated form. The following letter is written in its initial form, or isolated form if it is the final letter in the word.
• The letter alif originated in the Phoenician alphabet as a consonant-sign indicating a glottal stop. Today it has lost its function as a consonant, and, together with ya’ and wāw, is a mater lectionis, a consonant sign standing in for a long vowel (see below), or as support for certain diacritics (maddah and hamzah).
• Arabic currently uses a diacritic sign, ء, called hamzah, to denote the glottal stop [ʔ], written alone or with a carrier:
  • alone: ء
  • with a carrier: إ أ (above or under an alif), ؤ (above a wāw), ئ (above a dotless yā’ or yā’ hamzah).

In academic work, the hamzah (ء) is transliterated with the modifier letter right half ring (ʾ), while the modifier letter left half ring (ʿ) transliterates the letter ‘ayn (ع), which represents a different sound, not found in English.

The hamzah has a single form, since it is never linked to a preceding or following letter. However, it is sometimes combined with a wāw, yā’, or alif, and in that case the carrier behaves like an ordinary wāw, yā’, or alif.

The following are not individual letters, but rather different contextual variants of some of the Arabic letters.

Components of a ligature for "Allah":
1. alif
2. hamzat waṣl (ْهَمْزَة وَصْل)
3. lām
4. lām
5. shadda (شَدَّة)
6. dagger alif (أَلِفْ خَنْجَریَّة)
7. hāʾ

The use of ligature in Arabic is common. There is one compulsory ligature, that for lām ل + alif ا, which exists in two forms. All other ligatures, of which there are many,[5] are optional.

A more complex ligature that combines as many as seven distinct components is commonly used to represent the word Allāh.

The only ligature within the primary range of Arabic script in Unicode (U+06xx) is lām + alif. This is the only one compulsory for fonts and word-processing. Other ranges are for compatibility to older standards and contain other ligatures, which are optional.

• lām + alif

  لا

Note: Unicode also has in its Presentation Form B FExx range a code for this ligature. If your browser and font are configured correctly for Arabic, the ligature displayed above should be identical to this one, U+FEFB ARABIC LIGATURE LAM WITH ALEF ISOLATED FORM:

ﻻ

• U+0640 ARABIC TATWEEL + lām + alif

  ـلا

Note: Unicode also has in its Presentation Form B U+FExx range a code for this ligature. If your browser and font are configured correctly for Arabic, the ligature displayed above should be identical to this one:

• U+FEFC ARABIC LIGATURE LAM WITH ALEF FINAL FORM

  ﻼ

Another ligature in the Unicode Presentation Form A range U+FB50 to U+FDxx is the special code for glyph for the ligature Allāh ("God"), U+FDF2 ARABIC LIGATURE ALLAH ISOLATED FORM:

ﷲ

This is a work-around for the shortcomings of most text processors, which are incapable of displaying the correct vowel marks for the word Allāh in Koran. Because Arabic script is used to write other texts rather than Koran only, rendering lām + lām + hā’ as the previous ligature is considered faulty:[7] If one of a number of fonts (Noto Naskh Arabic, mry_KacstQurn, KacstOne, DejaVu Sans, Harmattan, Scheherazade, Lateef, Iranian Sans) is installed on a computer (Iranian Sans is supported by Wikimedia web-fonts), the word will appear without diacritics.

• lām + lām + hā’ = LILLĀH (meaning "to Allāh [only to Allah])

  لله  or   لله

• alif + lām + lām + hā’ = ALLĀH (the Islamic name for "God")

  الله  or   الله

• alif + lām + lām + U+0651 ARABIC SHADDA + U+0670 ARABIC LETTER SUPERSCRIPT ALEF + hā’

  اللّٰه   (DejaVu Sans and KacstOne don't show the added superscript Alef)

An attempt to show them on the faulty fonts without automatically adding the gemination mark and the superscript alif, although may not display as desired on all browsers, is by adding the U+200d (Zero width joiner) after the first or second lām

• (alif +) lām + lām + U+200d ZERO WIDTH JOINER + hā’

  الل‍ه   ‎   لل‍ه

Gemination is the doubling of a consonant. Instead of writing the letter twice, Arabic places a W-shaped sign called shaddah, above it. Note that if a vowel occurs between the two consonants the letter will simply be written twice. The diacritic only appears where the consonant at the end of one syllable is identical to the initial consonant of the following syllable. (The generic term for such diacritical signs is ḥarakāt).

Nunation (Arabic: تنوين‎ tanwīn) is the addition of a final -n  to a noun or adjective. The vowel before it indicates grammatical case. In written Arabic nunation is indicated by doubling the vowel diacritic at the end of the word.

In the Arabic handwriting of everyday use, in general publications, and on street signs, short vowels are typically not written. On the other hand, copies of the Qur’ān cannot be endorsed by the religious institutes that review them unless the diacritics are included. Children's books, elementary school texts, and Arabic-language grammars in general will include diacritics to some degree. These are known as "vocalized" texts.

Short vowels may be written with diacritics placed above or below the consonant that precedes them in the syllable, called ḥarakāt. All Arabic vowels, long and short, follow a consonant; in Arabic, words like "Ali" or "alif", for example, start with a consonant: ‘Aliyy, alif.

In the fully vocalized Arabic text found in texts such as Quran, a long ā following a consonant other than a hamzah is written with a short a sign (fatḥah) on the consonant plus an ʾalif after it; long ī is written as a sign for short i (kasrah) plus a yāʾ; and long ū as a sign for short u (ḍammah) plus a wāw. Briefly, ᵃa = ā; ⁱy = ī; and ᵘw = ū. Long ā following a hamzah may be represented by an ʾalif maddah or by a free hamzah followed by an ʾalif (two consecutive ʾalifs are never allowed in Arabic).

The table below shows vowels placed above or below a dotted circle replacing a primary consonant letter or a shaddah sign. For clarity in the table, the primary letters on the left used to mark these long vowels are shown only in their isolated form. Please note that most consonants do connect to the left with ʾalif, wāw and yāʾ written then with their medial or final form. Additionally, the letter yāʾ in the last row may connect to the letter on its left, and then will use a medial or initial form. Use the table of primary letters to look at their actual glyph and joining types.

In unvocalized text (one in which the short vowels are not marked), the long vowels are represented by the vowel in question: ʾalif ṭawīlah/maqṣūrah, wāw, or yāʾ. Long vowels written in the middle of a word of unvocalized text are treated like consonants with a sukūn (see below) in a text that has full diacritics. Here also, the table shows long vowel letters only in isolated form for clarity.

Combinations وا and يا are always pronounced wā and yāʾ respectively. The exception is the suffix ـوا۟ in verb endings where ʾalif is silent, resulting in ū or aw.

In addition, when transliterating names and loanwords, Arabic language speakers write out most or all the vowels as long (ā with ا ʾalif, ē and ī with ي yaʾ, and ō and ū with و wāw), meaning it approaches a true alphabet.

The diphthongs /aj/ and /aw/ are represented in vocalized text as follows:

An Arabic syllable can be open (ending with a vowel) or closed (ending with a consonant):

• open: CV [consonant-vowel] (long or short vowel)
• closed: CVC (short vowel only)

A normal text is composed only of a series of consonants plus vowel-lengthening letters; thus, the word qalb, "heart", is written qlb, and the word qalaba "he turned around", is also written qlb.

To write qalaba without this ambiguity, we could indicate that the l is followed by a short a by writing a fatḥah above it.

To write qalb, we would instead indicate that the l is followed by no vowel by marking it with a diacritic called sukūn ( ْ‎), like this: قلْب.

This is one step down from full vocalization, where the vowel after the q would also be indicated by a fatḥah: قَلْب.

The Qurʾān is traditionally written in full vocalization.

The long i sound in some editions of the Qur’ān is written with a kasrah followed by a diacritic-less y, and long u by a ḍammah followed by a bare w. In others, these y and w carry a sukūn. Outside of the Qur’ān, the latter convention is extremely rare, to the point that y with sukūn will be unambiguously read as the diphthong /aj/, and w with sukūn will be read /aw/.

For example, the letters m-y-l can be read like English meel or mail, or (theoretically) also like mayyal or mayil. But if a sukūn is added on the y then the m cannot have a sukūn (because two letters in a row cannot be sukūnated), cannot have a ḍammah (because there is never an uy sound in Arabic unless there is another vowel after the y), and cannot have a kasrah (because kasrah before sukūnated y is never found outside the Qur’ān), so it must have a fatḥah and the only possible pronunciation is /majl/ (meaning mile, or even e-mail). By the same token, m-y-t with a sukūn over the y can be mayt but not mayyit or meet, and m-w-t with a sukūn on the w can only be mawt, not moot (iw is impossible when the w closes the syllable).

Vowel marks are always written as if the i‘rāb vowels were in fact pronounced, even when they must be skipped in actual pronunciation. So, when writing the name Aḥmad, it is optional to place a sukūn on the ḥ, but a sukūn is forbidden on the d, because it would carry a ḍammah if any other word followed, as in Aḥmadu zawjī "Ahmad is my husband".

Another example: the sentence that in correct literary Arabic must be pronounced Aḥmadu zawjun shirrīr "Ahmad is a wicked husband", is usually mispronounced (due to influence from vernacular Arabic varieties) as Aḥmad zawj shirrīr. Yet, for the purposes of Arabic grammar and orthography, is treated as if it were not mispronounced and as if yet another word followed it, i.e., if adding any vowel marks, they must be added as if the pronunciation were Aḥmadu zawjun sharrīrun with a tanwīn 'un' at the end. So, it is correct to add an un tanwīn sign on the final r, but actually pronouncing it would be a hypercorrection. Also, it is never correct to write a sukūn on that r, even though in actual pronunciation it is (and in correct Arabic MUST be) sukūned.

Of course, if the correct i‘rāb is a sukūn, it may be optionally written.

ٰٰ The sukūn is also used for transliterating words into the Arabic script. The Persian word ماسک (mâsk, from the English word "mask"), for example, might be written with a sukūn above the ﺱ to signify that there is no vowel sound between that letter and the ک.

Some letters take a traditionally different form in specific regions:

Some modified letters are used to represent non-native sounds of Modern Standard Arabic. These letters are used in transliterated names, loanwords and dialectal words.

1. /t͡ʃ/ is considered a native phoneme/allophone in some dialects, e.g. Kuwaiti and Iraqi dialects.
2. /ʒ/ is considered a native phoneme in Levantine and North African dialects and as an allophone in others.
3. /ɡ/ is considered a native phoneme/allophone in most modern Arabic dialects.

In addition, the Arabic alphabet can be used to represent numbers (Abjad numerals). This usage is based on the ʾabjadī order of the alphabet. أ ʾalif is 1, ب bāʾ is 2, ج jīm is 3, and so on until ي yāʾ = 10, ك kāf = 20, ل lām = 30, ..., ر rāʾ = 200, ..., غ ghayn = 1000. This is sometimes used to produce chronograms.

Although Napoleon Bonaparte generally receives credit for introducing the printing press to Egypt during his invasion of that country in 1798, and though he did indeed bring printing presses and Arabic script presses to print the French occupation's official newspaper Al-Tanbiyyah ("The Courier"), printing in the Arabic language started several centuries earlier.

In 1514, following Gutenberg's invention of the printing press in 1450, Gregorio de Gregorii, a Venetian, published an entire prayer-book in Arabic script; it was entitled Kitab Salat al-Sawa'i and was intended for eastern Christian communities.[13]

Between 1580 and 1586, type designer Robert Granjon designed Arabic typefaces for Cardinal Ferdinando de' Medici, and the Medici press published many Christian prayer and scholarly Arabic texts in the late 16th century.[14]

Maronite monks at the Maar Quzhayy Monastery in Mount Lebanon published the first Arabic books to use movable type in the Middle East. The monks transliterated the Arabic language using Syriac script.

A goldsmith (like Gutenberg) designed and implemented an Arabic-script movable-type printing-press in the Middle East. The Greek Orthodox monk Abd Allah Zakhir set up an Arabic printing press using movable type at the monastery of Saint John at the town of Dhour El Shuwayr in Mount Lebanon, the first homemade press in Lebanon using Arabic script. He personally cut the type molds and did the founding of the typeface. The first book came off his press in 1734; this press continued in use until 1899.[15]

As of Unicode 13.0, the Arabic script is contained in the following blocks:[16]

• Arabic (0600–06FF, 255 characters)
• Arabic Supplement (0750–077F, 48 characters)
• Arabic Extended-A (08A0–08FF, 84 characters)
• Arabic Presentation Forms-A (FB50–FDFF, 611 characters)
• Arabic Presentation Forms-B (FE70–FEFF, 141 characters)
• Rumi Numeral Symbols (10E60–10E7F, 31 characters)
• Indic Siyaq Numbers (1EC70–1ECBF, 68 characters)
• Ottoman Siyaq Numbers (1ED00–1ED4F, 61 characters)
• Arabic Mathematical Alphabetic Symbols (1EE00—1EEFF, 143 characters)

The basic Arabic range encodes the standard letters and diacritics but does not encode contextual forms (U+0621-U+0652 being directly based on ISO 8859-6). It also includes the most common diacritics and Arabic-Indic digits. U+06D6 to U+06ED encode Qur'anic annotation signs such as "end of ayah" ۝ۖ and "start of rub el hizb" ۞. The Arabic supplement range encodes letter variants mostly used for writing African (non-Arabic) languages. The Arabic Extended-A range encodes additional Qur'anic annotations and letter variants used for various non-Arabic languages.

The Arabic Presentation Forms-A range encodes contextual forms and ligatures of letter variants needed for Persian, Urdu, Sindhi and Central Asian languages. The Arabic Presentation Forms-B range encodes spacing forms of Arabic diacritics, and more contextual letter forms. The Arabic Mathematical Alphabetical Symbols block encodes characters used in Arabic mathematical expressions.

Arabic Mac keyboard layout

Arabic PC keyboard layout

Intellark imposed on a QWERTY keyboard layout.

Keyboards designed for different nations have different layouts so proficiency in one style of keyboard, such as Iraq's, does not transfer to proficiency in another, such as Saudi Arabia's. Differences can include the location of non-alphabetic characters.

All Arabic keyboards allow typing Roman characters, e.g., for the URL in a web browser. Thus, each Arabic keyboard has both Arabic and Roman characters marked on the keys. Usually the Roman characters of an Arabic keyboard conform to the QWERTY layout, but in North Africa, where French is the most common language typed using the Roman characters, the Arabic keyboards are AZERTY.

To encode a particular written form of a character, there are extra code points provided in Unicode which can be used to express the exact written form desired. The range Arabic presentation forms A (U+FB50 to U+FDFF) contain ligatures while the range Arabic presentation forms B (U+FE70 to U+FEFF) contains the positional variants. These effects are better achieved in Unicode by using the zero-width joiner and non-joiner, as these presentation forms are deprecated in Unicode, and should generally only be used within the internals of text-rendering software, when using Unicode as an intermediate form for conversion between character encodings, or for backwards compatibility with implementations that rely on the hard-coding of glyph forms.

Finally, the Unicode encoding of Arabic is in logical order, that is, the characters are entered, and stored in computer memory, in the order that they are written and pronounced without worrying about the direction in which they will be displayed on paper or on the screen. Again, it is left to the rendering engine to present the characters in the correct direction, using Unicode's bi-directional text features. In this regard, if the Arabic words on this page are written left to right, it is an indication that the Unicode rendering engine used to display them is out of date.[17][18]

There are competing online tools, e.g. Yamli editor, which allow entry of Arabic letters without having Arabic support installed on a PC, and without knowledge of the layout of the Arabic keyboard.[19]

The first software program of its kind in the world that identifies Arabic handwriting in real time was developed by researchers at Ben-Gurion University (BGU).

The prototype enables the user to write Arabic words by hand on an electronic screen, which then analyzes the text and translates it into printed Arabic letters in a thousandth of a second. The error rate is less than three percent, according to Dr. Jihad El-Sana, from BGU's department of computer sciences, who developed the system along with master's degree student Fadi Biadsy.[20]
