U+0637 "ط" Arabic Letter Tah Unicode Character

Unicode Version 17.0

ط

U+0637 "ط" Arabic Letter Tah is the seventeenth letter of the Arabic alphabet, representing a pharyngealized voiceless dental plosive sound, similar to a heavy or emphatic "t" pronounced with the tongue pressed against the upper teeth and a constricted throat. It is a lunar letter in Arabic grammar, meaning it does not cause the following "alif lam" definite article to assimilate, and it belongs to the group of emphatic consonants that give Arabic its distinctive depth. In calligraphy, "ط" features a tall vertical stroke with a small rounded head, and it appears in words like "طبيب" (doctor) and "طريق" (road), contributing to both semantic and phonetic richness in the language. This character is also used in other languages that employ the Arabic script, such as Persian and Urdu, where it similarly denotes an emphatic "t" sound.
