U+1FF3 "ῳ" Greek Small Letter Omega with Ypogegrammeni Unicode Character

Unicode Version 17.0

U+1FF3 "ῳ" Greek Small Letter Omega with Ypogegrammeni is a historical Greek character used in ancient polytonic writing, consisting of the letter omega combined with a small iota subscript (ypogegrammeni) written below it. This digraph represents a long omega sound followed by the vowel iota, which was originally pronounced but later became a silent diacritical mark in many Greek texts. It appears primarily in classical and liturgical contexts, such as in the word "τῇ" for the feminine dative singular article. In modern Greek, this character is largely obsolete, having been replaced by the simple omega in monotonic orthography, though it remains important for the accurate rendering of ancient manuscripts and scholarly editions.
