An abjad is a type of writing system where each symbol stands for a consonant, leaving the reader to supply the appropriate vowel. It is a term suggested by Peter T. Daniels to replace the common terms "consonantary", "consonantal alphabet" or "syllabary" to refer to the family of scripts called West Semitic.
The name "abjad" (abjad أبجد) is derived from pronouncing the first letters of the Arabic alphabet in order. The ordering (abjadī) of Arabic letters used to match that of the older Hebrew, Phoenician and Semitic alphabets; ʾ b g d.
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 defined 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 ḥarakāt for Arabic, their use is optional and not the dominant (or literate) form. Abugidas 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.
The term Semitic or Semite most commonly refers to the Semitic languages, a language family currently present in West Asia, North and East Africa, and Malta
Semitic may also refer to:
The Semitic languages are a branch of the Afroasiatic language family originating in the Middle East. Semitic languages are spoken by more than 330 million people across much of Western Asia, North Africa and the Horn of Africa, as well as in large expatriate communities in North America and Europe. The terminology was first used in the 1780s by German orientalists von Schlözer and Eichhorn, who derived the name from Shem, one of the three sons of Noah in the Book of Genesis.
The most widely spoken Semitic languages today are (numbers given are for native speakers only) Arabic (300 million),Amharic (22 million),Tigrinya (7 million), and Hebrew (unknown; 5 million native and non-native L1 speakers).
Semitic languages are attested in written form from a very early date, with Akkadian and Eblaite texts (written in a script adapted from Sumerian cuneiform) appearing from around the middle of the third millennium BC in Mesopotamia and the northern Levant respectively. However, most scripts used to write Semitic languages are abjads—a type of alphabetic script that omits some or all of the vowels, which is feasible for these languages because the consonants in the Semitic languages are the primary carriers of meaning.
