Unicode Version 17.0

ض

U+0636 "ض" Arabic Letter Dad is the fifteenth letter of the Arabic alphabet, representing the emphatic voiced alveolar lateral fricative sound /dˤ/, a consonant articulated with the tongue pressed against the upper teeth and pharynx constricted. This letter is famously known as the "ضاد" (ḍād), from which the Arabic language derives its traditional name "لغة الضاد" (the language of the ḍād), because this unique pharyngealized sound is considered one of the most distinctive features of Arabic phonology. In the modern standard Arabic writing system, the letter takes different forms depending on its position in a word, including isolated, initial, medial, and final shapes, and it is used in a wide range of common words, including "رمضان" (Ramadan) and "مصر" (Egypt). The character is encoded in the Unicode Standard at code point U+0636 as part of the Arabic block, allowing it to be represented and displayed consistently across digital platforms.
