U+1FA1 "ᾡ" Greek Small Letter Omega with Dasia and Ypogegrammeni Unicode Character
U+1FA1 "ᾡ" Greek Small Letter Omega with Dasia and Ypogegrammeni is a historical Greek letter used primarily in ancient polytonic orthography, where it represents a long omega vowel that begins with a rough breathing mark, known as dasia, and is followed by an iota subscript, or ypogegrammeni, indicating a long diphthong. This character appears in edited classical texts, such as those of Homer or Attic drama, to denote a specific pronunciation and grammatical inflection, typically in verb endings or noun forms where the omega combines with an underlying iota sound. It is part of the Greek Extended block in Unicode and is rarely used in modern Greek, which employs monotonic spelling, but it remains essential for accurate scholarly reproduction of ancient manuscripts and linguistic studies.
