U+1F84 "ᾄ" Greek Small Letter Alpha with Psili and Oxia and Ypogegrammeni Unicode Character

Unicode Version 17.0

U+1F84 "ᾄ" Greek Small Letter Alpha with Psili and Oxia and Ypogegrammeni is a precomposed form used in classical and polytonic Greek, combining the alpha vowel with three distinct diacritical marks: a smooth breathing mark (psili, indicating no initial /h/ sound), an acute accent (oxia, marking a high-pitched or stressed syllable), and an iota subscript (ypogegrammeni, a small iota written beneath the letter to represent a long vowel sound that was once followed by a short iota in Ancient Greek). This specific character is part of the Greek Extended Unicode block and is primarily employed in scholarly texts, liturgical writings, and editions of ancient Greek literature to accurately represent the orthography and pronunciation of words such as "ᾄδω" (I sing), where the combination of these diacritics conveys essential grammatical and phonological information that was characteristic of the Greek language before the medieval simplification of its accentuation system.
