Ẓāʾ, or ḏ̣āʾ (ظ), is one of the six letters the Arabic alphabet added to the twenty-two inherited from the Phoenician alphabet (the others being ṯāʾ, ḫāʾ, ḏāl, ḍād, ġayn). In Classical Arabic, it represents a velarized voiced dental fricative [ðˠ], and in Modern Standard Arabic, it can also be a pharyngealized, [ðˤ] voiced dental fricative or voiced alveolar fricative [zˤ]. In name and shape, it is a variant of ṭāʾ. Its numerical value is 900 (see Abjad numerals).
Ẓāʾ does not change its shape depending on its position in the word:

In Classical Arabic, it represents a velarized voiced dental fricative [ðˠ], and in Modern Standard Arabic, it can also be a pharyngealized, [ðˤ] voiced dental fricative or voiced alveolar fricative [zˤ].
In most Arabic vernaculars ظ ẓāʾ and ض ḍād have been merged quite early. The outcome depends on the dialect. In those varieties (such as Egyptian, Levantine and Hejazi), where the dental fricatives /θ/, /ð/ are merged with the dental stops /t/, /d/, ẓāʾ is pronounced /dˤ/ or /zˤ/ depending on the word; e.g. ظِل is pronounced /dˤilː/ but ظاهِر is pronounced /zˤaːhir/, In loanwords from Classical Arabic ẓāʾ is often /zˤ/, e.g. Egyptian ʿaẓīm (< Classical عظيم ʿaḏ̣īm) "great".
In the varieties (such as Bedouin and Iraqi), where the dental fricatives are preserved, both ḍād and ẓāʾ are pronounced /ðˤ/. However, there are dialects in South Arabia and in Mauritania where both the letters are kept different but not consistently.
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. However, there do exist Arabic borrowings into Ibero-Romance languages as well as Hausa and Malay, where ḍād and ẓāʾ are differentiated.
In other Semitic languages
In some reconstructions of Proto-Semitic phonology, there is an emphatic interdental fricative, ṱ ([θˤ] or [ðˤ]), featuring as the direct ancestor of Arabic ẓāʾ, while it merged with ṣ in most other Semitic languages, although the South Arabian alphabet retained a symbol for ẓ.
Writing in the Hebrew alphabet
When representing this sound in transliteration of Arabic into Hebrew, it is written as ט׳.
