Ẓāʾ, orḏ̣āʾ (ظ), is the seventeenth letter of theArabic alphabet, one of the six letters not in the twenty-two akin to thePhoenician alphabet (the others beingṯāʾ,ḫāʾ,ḏāl,ḍād,ġayn). In name and shape, it is a variant ofṭāʾ. Its numerical value is 900 (seeAbjad numerals). It is related to theAncient North Arabian 𐪜, andSouth Arabian𐩼.

Ẓāʾ is the rarest phoneme of the Arabic language. Out of 2,967 triliteral roots listed byHans Wehr in his1952 dictionary, only 42 (1.4%) containظ.[1]Ẓāʾ is the least mentioned letter in theQuran, only being mentioned 853 times in the Quran.
In relation to other Semitic languages
In some reconstructions ofProto-Semitic phonology, there is anemphatic interdental fricative,ṯ̣/ḏ̣ ([θˤ] or[ðˤ]), featuring as the direct ancestor of Arabicẓādʾ, while it merged withṣ in most otherSemitic languages, although theSouth Arabian alphabet retained a symbol forẓ.

InClassical Arabic, it represents avelarized voiced dental fricative[ðˠ], and inModern Standard Arabic, it represents anpharyngealized voiced dental[ðˤ] but can also be a alveolar[zˤ] fricative for a number of speakers.
In most Arabic vernacularsظẓāʾ andضḍād merged quite early.[2] The outcome depends on the dialect. In those varieties (such asEgyptian andLevantine), where thedental fricatives/θ/ and/ð/ are merged with thedental stops/t/ and/d/,ẓādʾ is pronounced/dˤ/ or/zˤ/ depending on the word; e.g.ظِل is pronounced/dˤɪl/ butظاهِر is pronounced/zˤaːhɪr/, In loanwords from Classical Arabicẓāʾ is often/zˤ/, e.g. Egyptianʿaẓīm (< Classicalعظيمʿaḏ̣īm) "great".[2][3][4]
In the varieties (such asBedouin,Tunisian, andIraqi), where the dental fricatives are preserved, bothḍād andẓāʾ are pronounced/ðˤ/.[2][3][5][6] However, there are dialects in South Arabia and inMauritania where both the letters are kept different but not consistently.[2]
A "de-emphaticized" pronunciation of both letters in the form of the plain/z/ entered into other non-Arabic languages such as Persian, Urdu, Turkish.[2] However, there do exist Arabic borrowings intoIbero-Romance languages as well asHausa andMalay, whereḍād andẓāʾ are differentiated.[2]
In English, the sound is sometimes represented by the digraphzh.
