U+1F04 "ἄ" Greek Small Letter Alpha with Psili and Oxia Unicode Character
Unicode Version 17.0
ἄ
U+1F04 "ἄ" Greek Small Letter Alpha with Psili and Oxia is a precomposed Greek letter used in polytonic orthography, representing the vowel alpha combined with two diacritics: the psili (smooth breathing mark) and the oxia (acute accent). This character indicates that the alpha is pronounced with a smooth, unaspirated initial sound and carries a rising pitch on the accented syllable, typical of Ancient Greek. It appears in classical texts such as those by Homer or Plato, where it helps convey precise pronunciation and grammatical meaning. In modern Greek, polytonic diacritics are largely replaced by monotonic accentuation, so this character is now primarily encountered in scholarly or liturgical contexts rather than everyday writing.
