For the traditional ordering of the letters of the Arabic alphabet, see Abjad numerals.

An abjad is a type of writing system in which each symbol always or usually[1] stands for a consonant; the reader must supply the appropriate vowel. It is a term suggested by Peter T. Daniels[2] to replace the common terms consonantary or consonantal alphabet or syllabary to refer to the family of scripts called West Semitic. In popular usage, abjads often contain the word "alphabet" in their names, such as "Arabic alphabet" and "Phoenician alphabet". The name abjad itself derives from the Arabic word for alphabet. The word "Alphabet" in English has a source in Greek language the first two letters of which were A (Alpha) and B (Beta), hence Alphabeta. In Arabic, A (ʾAlif), B (Bāʾ), Ǧ (Ǧīm), D (Dāl) make the word "Abjad" which means "Alphabet". It is also used to enumerate a list in the same manner that a,b,c,d etc. are used in the English language.

The name "Abjad" (ʾabǧad أبجد) derives from pronouncing the first letters of the alphabet in order. The old ordering (ʾabǧadī ) of Arabic letters used to match that of Hebrew, Phoenician and Semitic alphabets; ʾ b g d (read from right-to-left: أ ب ج د) or أبجد.

Terminology Edit

According to the formulations of Daniels, abjads differ from alphabets in that only consonants, not vowels, are represented among the basic graphemes. Abjads differ from abugidas, another category invented by Daniels, in that in abjads the vowel sound is implied by phonology, and where vowel marks exist for the system, such as nikkud for Hebrew and harakāt for Arabic, their use is optional and not the dominant (or literate) form. Abugidas always mark the vowels (other than the "inherent" vowel) with a diacritic, a minor attachment to the letter, or a standalone glyph. Some abugidas use a special symbol to suppress the inherent vowel so that the consonant alone can be properly represented. In a syllabary, a grapheme denotes a complete syllable, that is, either a lone vowel sound or a combination of a vowel sound with one or more consonant sounds.



All known abjads belong to the Semitic family of scripts. These scripts are thought to derive from the Proto-Sinaitic alphabet (dated to about 1500 BC) which is thought to derive from Egyptian hieroglyphs. The abjad was significantly simpler than the earlier hieroglyphs. The number of distinct glyphs was reduced tremendously, at the cost of increased ambiguity.

The first abjad to gain widespread usage was the Phoenician abjad. Unlike other contemporary scripts, such as Cuneiform and Egyptian hieroglyphs, the Phoenician script consisted of only about two dozen symbols. This made the script easy to learn, and Phoenician seafaring merchants took the script wherever they went. Phoenician gave way to a number of new writing systems, including the Greek alphabet, and Aramaic, a widely used abjad. Greek evolved into the modern western alphabets, such as Latin and Cyrillic, while Aramaic became the ancestor of many modern abjads and abugidas of Asia.

Aramaic spread across Asia, reaching as far as India and becoming Brahmi, the ancestral abugida to most modern Indian and Southeast Asian scripts. In the Middle East, Aramaic gave rise to the Hebrew and Nabataean abjads, which retained many of the Aramaic letter forms. The Syriac script was a cursive variation of Aramaic. It is unclear whether the Arabic abjad was derived from Nabatean or Syriac.

Impure abjadsEdit

"Impure" abjads have characters for some vowels, optional vowel diacritics, or both. The term "pure" abjad refers to scripts entirely lacking in vowel indicators. However, most modern abjads, such as Arabic, Hebrew, Aramaic and Avestan, are "impure" abjads, that is, they also contain symbols for some of the vowel phonemes. An example of a pure abjad is ancient Phoenician.

Addition of vowelsEdit

In the 9th century BC, the Greeks adapted the Phoenician script for use in their own language. The phonetic structure of the Greek language created too many ambiguities when the vowels went unrepresented, so the script was modified. They did not need letters for the guttural sounds represented by aleph, he, heth or ayin, so these symbols were assigned vocalic values. The letters waw and yod were also used. The Greek alphabet thus became the world's first "true" alphabet.

Abugidas developed along a slightly different route. The basic consonantal symbol was considered to have an inherent "a" vowel sound. Hooks or short lines attached to various parts of the basic letter modify the vowel. In this way, the South Arabian alphabet evolved into the Ge'ez alphabet between the 5th century BC and the 5th century AD. Similarly, around the 3rd century BC, the Brāhmī script developed (from the Aramaic abjad, it has been hypothesised).

Abjads and the structure of Semitic languagesEdit

The abjad form of writing is well-adapted to the morphological structure of the Semitic languages it was developed to write. This is because words in Semitic languages are formed from a root consisting of (usually) three consonants, the vowels being used to indicate inflectional or derived forms. For instance, according to Classical Arabic, not Modern Standard Arabic, the Arabic root ذ ب ح Ḏ-B-Ḥ (to sacrifice) can be derived the forms ذَبَح ḏabaḥa (he sacrificed), ذَبَحْتَ ḏabaḥta (you (masculine singular) sacrificed), ذَبَّحَ ḏabbaḥa (he slaughtered), يُذَبِّح yuḏabbiḥ (he slaughters), and مَذْبَح maḏbaḥ (slaughterhouse). In each case, the absence of full glyphs for vowels makes the common root clearer, improving word recognition[citation needed][dubious ] while reading.
