U+0619 "ؙ" Arabic Small Damma Unicode Character

U+0619 "ؙ" Arabic Small Damma is a diacritical mark used in Arabic script, primarily within Quranic and religious texts, to indicate a very short or reduced version of the "damma" vowel, which normally represents an /u/ sound. Unlike the standard damma, this small variant often appears above a letter to denote an extremely brief, sometimes almost imperceptible, rounding of the lips during pronunciation, arising in specific contexts such as recitation rules or precise orthographic conventions. Its use is highly specialized and rare in modern everyday Arabic writing, serving instead as a tool for exactly preserving the phonetic details of the language in classical or liturgical contexts.
