The Arabic alphabet is the principal script used for writing the Arabic language. It is the alphabet of the language of the Quran, the holy book of Islam. The alphabet's influence spread with that of Islam and it has been, and still is, used to write other languages without any linguistic roots in Arabic, such as Persian and Urdu. (See fuller list below.)

It is often necessary to add or modify certain letters in order to adapt this alphabet to the phonology of the target languages.

Structure of the Arabic alphabet

The Arabic alphabet is composed of 28 basic letters and is written from right to left. There is no difference between written and printed letters; the writing is unicase (i.e. the concept of upper and lower case letters does not exist). On the other hand, most of the letters are attached to one another, even when printed, and their appearance changes as a function of whether they are preceded or followed by other letters or stand alone (that is, there is contextual variation and ligature).

The Arabic alphabet is an impure abjad - since short vowels are not written, though long ones are - so the reader must know the language in order to restore the vowels. However, in editions of the Quran or in didactic works a vocalization notation in the form of diacritic marks is used. Moreover, in vocalized texts, there is a series of other diacritics of which the most modern are an indication of vowel omission (sukūn) and the lengthening of consonants (šadda).

Presentation of the alphabet

The Arabic alphabet can be transliterated and transcribed in various ways. The preferred method in this document will be DIN-31635. Alternatives belonging to other standards are indicated after the oblique bar.

Notice that the horizontal-line diacritic above the long vowels is often replaced by a circumflex, because it happens to be easier to type in many keyboards.

A transliteration from Arabic must allow the reconstruction of the original Arabic letters, so it shows the characters which are not pronounced or which are pronounced as others. A phonemic transcription indicates only the pronunciation. See below for more details. The phonemic transcription (somewhat simplified here) follows the conventions of the International Phonetic Alphabet: for more details concerning the pronunciation of Arabic, consult the article on Arabic pronunciation.

SATTS, the Standard Arabic Technical Transliteration System, is a US military standard transliteration of Arabic letters to the Latin alphabet.

Notes

The ʾalif maqṣūra, commonly using Unicode 0x0649 (ى) in Arabic, is sometimes replaced in Persian or Urdu, with Unicode 0x06CC (ی), called "Farsi Yeh". This is appropriate to its pronunciation in those languages. The glyphs are identical in isolated and final form (ﻯ ﻰ), but not in initial and medial form, in which the Farsi Yeh gains two dots below (ﯾ ﯿ) while the ʾalif maqṣūra has neither an initial nor a medial form.

Writing the hamza

Initially, the letter ʾalif indicated an occlusive glottal, or glottal stop, transcribed by [ʔ], confirming the alphabet came from the same Phoenician origin. Now it is used in the same manner as in other abjads, with yāʾ and wāw, as a mater lectionis, that is to say, a consonant standing in for a long vowel (see below). In fact, over the course of time its phonetic value has been obscured, since, ʾalif serves principally to replace phonemes or to serve as a graphic support for certain diacritics.

The Arabic alphabet now mainly uses the hamza to indicate a glottal stop, which can appear anywhere in a word. This letter, however, does not function like the others: it can be written alone or on a support in which case it becomes a diacritic:

• alone : ء ;
• with a support : إ, أ (above and under a ʾalif), ؤ (above a wāw), ئ (above a yāʾ without points or yāʾ hamza).

The details of writing of the hamza are discussed below, after that of the vowels and syllable-division marks, because their functions are related.

Ligatures

The only compulsory ligature is lām+'alif. All other ligatures (yaa - meem, etc) are optional.

Some fonts include a (Sall-allahu alayhi wasallam) glyph:

and a glyph for the word Allah:

The former is used by Muslims after any mention of the Islamic prophet Muhammad. The latter is a work-around for the shortcomings of most text processors, which are incapable of displaying the correct vowel marks for the word "Allah". Compare the display below, which depends on your browser and installed fonts:

للّٰه

Diacritics

Vowels

Arabic short vowels are generally not written, except sometimes in sacred texts (such as the Quran) and didactics, which are known as vocalised texts.

Short vowels may be written with diacritics placed above or below the consonant that precedes them in the syllable. (All Arabic vowels, long and short, follow a consonant; contrary to appearances: there is a consonant at the start of a name like Ali in Arabic ʾAlī or a word like ʾalif.)

Long "a" following a consonant other than hamzah is written with a short-"a" mark on the consonant plus an alif after it (ʾalif). Long "i" is a mark for short "i" plus a yaa yāʾ, and long u is mark for short u plus waaw, so aā = ā, iy = ī and uw = ū);

Long "a" following a hamzah sound may be representend by an alif-madda or by a floating hamzah followed by an alif.

In an un-vocalised text (one in which the short vowels are not marked), the long vowels are represented by the consonant in question (alif, yaa, waaw). Long vowels written in the middle of a word are treated like consonants taking sukūn (see below) in a text that has full diacritics.

For clarity, vowels will be placed above or below the letter د dāl so it is necessary to read the results [da], [di], [du], etc. Please note, د dāl is one of the six letters that do not connect to the left, and is used in this demonstration for clarity. Most other letters connect to ʾalif, wāw and yāʾ.

Syllabation signs and others

Shadda

ّ shadda marks gemination of a consonant; kasra (see below) moves to between the shadda and the geminate consonant when present.

Sukūn

An Arabic syllable can be open (ended by a vowel) or closed (ended by a consonant).

• open: C[onsonant]V[owel];
• closed: CVC(C).

When the syllable is closed, we can indicate that the consonant that closes it does not carry a vowel by marking it with a sign called sukūn, which takes the form "°", to remove any ambiguity, especially when the text is not vocalised: it's necessary to remember that a standard text is only composed of series of consonants; thus, the word qalb, "heart", is written qlb. Sukūn allows us to know where not to place a vowel: qlb could, in effect, be read /qVlVbV/, but written with a sukūn over the l and the b, it can only be interpreted as the form /qVlb/ (as for knowing which vowel to use, the word has to be memorised); we write this قلْبْ (without ligature: ق‌لْ‌بْ).

You might think that in a vocalised text sukūn is not necessary, because the lack of vowel after a consonant might be signalled by simply not writing any mark above it, so قِلْبْ would be redundant. That is not so because such a convention ("lack of any vowel mark means lack of vowel sound") does not exist: k + u + t + b may indeed be read "kutib". Such a rule would make sense if everybody writing a vowel mark were forced to write all vowel marks in the same word, and that is not the case. In fact, you may write as many or as few of the vowel marks as you like.

In the Quran, however, all vowel marks must be written: there, sukuun over a letter (other than the alif indicating long "a") indicates that it is pronounced but not followed by a short vowel, while the lack of any sign over a letter (other than alif) indicates that the consonant is not pronounced.

Outside of the qur'aan, putting a sukuun above a yaa' which indicates long ee, or above a waaw which stands for long oo, is extremely rare, to the point that yaa with sukuun will be unambiguously read as the diphthong ai (as in Englis "eye") and waaw with sukuun will be read au (as in English "cow").

So, the word zauǧ, "husband", can be written simply zwǧ : زوج (which might be also read "zooj" if such a word existed); or with sukūn  زوْجْ which is unambiguously "zowj"; or with sukūn and vowels: زَوْج.

The letters mwsyqā (موسيقى with a ʾalif maqṣūra at the end of the word) will be read most naturally as the word "mooseekaa" ("music"). If you were to write sukuuns above the waaw, yaa and alif, you'd get موْسيْقىْ, which looks like "mowsaykay". (note that an ʾalif maqṣūra is an alif and never takes sukūn, so when you put a sukuun above it, it loks like a yaa deprived of its two dots below).

You cannot place a sukuun on the final letter j of "zawj" even if you don't pronounce a vowel there, because fully vocalised texts are always written as if the ighraab vowels were in fact pronounced, and this word can never have a sukuun as an ighraab. Let's take the sentence "ahmad zawj sharr", meaning "Ahmed is a bad husband". The theoretical pronunciation with the ighraab vowels is "ahmadu zaujun sharr". Interestingly, regardless of the fact that most people say "ahmad zauj sharr", you cannot write the mark for sukuun over that j; you either leave it marless, or use the mark for "un". By the same token, you can leave the final r of this sentence either completely unmarked or topped with a shadda plus "un", but a sukuun never belngs there, regardless of the fact that the only correct pronunciation of "sharrun" at the end of an utterence is "shar".

Arabic numerals

There are two kinds of numerals used in Arabic writing; standard Arabic numerals, and "EastArab" numerals, used in Arab writing in Iran, Pakistan and India. In Arabic, these numbers are referred to as "Indian numbers" (أرقام هندية). In most of present-day North Africa, the usual Western numerals are used; in medieval times, a slightly different set (from which, via Italy, Western "Arabic numerals" derive) was used.

Standard numerals ٠ 0 ١ 1 ٢ 2 ٣ 3 ٤ 4 ٥ 5 ٦ 6 ٧ 7 ٨ 8 ٩ 9

EastArab numerals ۰ 0 ۱ 1 ۲ 2 ۳ 3 ۴ 4 ۵ 5 ۶ 6 ۷ 7 ۸ 8 ۹ 9

In addition, the Arabic alphabet can be used to represent numbers, a usage rare today. This usage is based on a different and older order of the alphabet: أ ب ج د ه و ز ح ط ي ك ل م ن س ع ف ص ق ر ش ت ث خ ذ ض ظ غ. (In the Maghreb and West Africa, a few of these letters are transposed.) أ alif is 1, ب ba is 2, ج jim is 3, and so on until ي ya = 10, ك kaf = 20, ل lam = 30, ... ر ra = 200, ..., غ ghayn = 1000. This is sometimes used to produce chronograms.

History

The Arabic alphabet can be traced back to the alphabet used to write the Nabataean dialect of Aramaic, itself descended from Phoenician (which, among others, gave rise to the Greek alphabet and, thence, to Latin letters, etc.). The first known text in the Arabic alphabet is a late fourth-century inscription from Jabal Ramm (50 km east of Aqaba), but the first dated one is a trilingual inscription at Zebed in Syria from 512. However, the epigraphic record is extremely sparse, with only five certainly pre-Islamic Arabic inscriptions surviving, though some others may be pre-Islamic. Later, dots were added above and below the letters to differentiate them (the Aramaic model had fewer phonemes than the Arabic, and some originally distinct Aramaic letters had become indistinguishable in shape, so in the early writings 15 distinct letter-shapes had to do duty for 28 sounds!) The first surviving document that definitely uses these dots is also the first surviving Arabic papyrus (PERF 558), dated April 643, although they did not become obligatory until much later.

Yet later, vowel signs and hamza s were added, beginning sometime in the last half of the sixth century, roughly contemporaneous with the first invention of Syriac and Hebrew vocalization. Initially, this was done by a system of red dots, said to have been commissioned by an Umayyad governor of Iraq, Hajjaj ibn Yusuf : a dot above = a, a dot below = i, a dot on the line = u, and doubled dots gove tanwin. However, this was cumbersome and eaily confusable with the letter-distinguishing dots, so about 100 years later, the modern system was adopted. The system was finalized around 786 by al-Farahidi .

Arabic alphabets of other languages

Arabic script is not used solely for writing Arabic, but for a variety of languages. In each language it is used for, it has been modified to fit the language's sound system. There are phonemes not found in Arabic, but found in, for instance, Persian and Malay and Urdu - especially since those three languages are not related to Arabic. For example, the Arabic language lacks a "P" sounding letter, so many languages add their own "P" in the script, though the symbol used may differ between languages. These modifications tend to fall into groups; so all the Indian and Turkic languages written in Arabic tend to use the Persian modified letters, whereas West African languages tend to imitate those of Ajami , and Indonesian ones those of Jawi. The script in which the Persian modified letters are used, is called Perso-Arabic script by the scholars.

The Arabic alphabet is currently used for:

• Persian and Azeri in Iran;

• Punjabi in Pakistan, where it is known as Shahmukhi;

• Pashto, and Uzbek in Afghanistan;

• Urdu, Kashmiri, Sindhi, and Baluchi in Pakistan and India;

• Malay in Brunei, where it is called Jawi;

• Kurdish and Turkmen in Northern Iraq (in Turkey Latin alphabet is now used for Kurdish);

• Comorian (Comorian) in the Comoros, currently side by side with the Latin alphabet (neither is official);

• Kyrgyz in China;

• Uyghur and Kazakh in northwest China (Xinjiang), and previously in Kazakhstan;

• Hausa for many purposes, especially religious (known as Ajami );

• Mandinka;

• Wolof (at zaouias), known as Wolofal .

In the past, it has also been used to represent other languages:

• Albanian;

• Azeri in Azerbaijan (now written in Latin alphabet and Cyrillic alphabet scripts in Azerbaijan);

• Berber in North Africa, particularly Tachelhit in Morocco (still being considered, along with Tifinagh and Latin for Tamazight);

• Bashkir (for some years: from October revolution till 1928);

• Bosnian;

• Chaghatai across Central Asia;

• Chechen (for some years: from October revolution till 1928);

• Fulani , known as Ajami ;

• Kyrgyz in Kyrgyzstan;

• Malay in Malaysia and Indonesia;

• Nubian;

• Swahili;

• Somali ( Has used the Latin alphabet since 1972);

• Songhay in West Africa, particularly in Timbuktu;

• Tatar (iske imlâ ) before 1928 (changed to Latin), reformed in 1880-s, 1918 (deletion of some letters);

• Turkish in the Ottoman Empire was written in Arabic script until Mustafa Kemal Atatürk declared the change to Roman script in 1928. This form of Turkish is now known as Ottoman Turkish and is held by many to be a different language, due to its much higher percentage of Persian and Arabic loanwords;

• Turkmen in Turkmenistan;

• Uzbek in Uzbekistan;

• All the Muslim peoples of the USSR between 1918-1928 (many also earlier), including Bashkir, Chechen, Kazakh, etc. After 1928 their script became Latin, then later Cyrillic;

• Afrikaans (as was first written among the "Cape Malays");

• Belarusian (among ethnic Tatars);

• Mozarabic, when the Moors ruled Spain (and later Aragonese, Portuguese, and Spanish proper; see aljamiado);

• Chinese and Dungan, among the Chinese Hui Muslims[1] http://www.aa.tufs.ac.jp/~kmach/xiaoerjin/xiaoerjin-e.htm ;

• Sanskrit has also been written in Arabic script, though it is more well known as using the Devanagari script - the same script used for writing the Hindi language.

Computers and the Arabic alphabet

The Arabic alphabet can be encoded using several character sets, including ISO-8859-6 and Unicode, thanks to the "Arabic segment": entries U+0600 to U+06FF. However, these two sets do not indicate the form each character should take in context. It is left to the rendering engine to select the proper glyph to display for each character.

When one wants 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 Arabic presentation forms A (U+FB50 to U+FDFF) and Arabic presentation forms B (U+FE70 to U+FEFF) contain most of the characters with contextual variation as well as the extended characters appropriate for other languages. 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. For more information about encoding Arabic, consult the Unicode manual available at http://www.unicode.org/
