U+064F "ُ" Arabic Damma Unicode Character

Unicode Version 17.0

ُ

U+064F "ُ" Arabic Damma is a diacritical mark used in the Arabic script to represent the short vowel sound /u/, similar to the "u" in the English word "put." It is placed above a consonant letter to indicate this vowel, and it plays a crucial role in the Arabic language for correct pronunciation and grammatical inflection, especially in formal or Classical Arabic. As an integral part of the Arabic writing system, the Damma helps distinguish word meanings and syntactic structures that would otherwise be ambiguous without vowel markers.
