U+0621 "ء" Arabic Letter Hamza Unicode Character
Unicode Version 17.0
ء
U+0621 "ء" Arabic Letter Hamza is a distinct glyph representing the glottal stop sound, which is a phonemic consonant in the Arabic language. Unlike other Arabic letters, hamza can appear in different positional forms when combined with seat letters (such as alif, waw, or ya) but, as a standalone character, it sits alone above the line with a small circular shape. This symbol is fundamental in Arabic orthography, as it distinguishes word meanings and grammatical structures, and is also used in other languages that employ the Arabic script, such as Persian and Urdu.
