U+0251 "ɑ" Latin Small Letter Alpha Unicode Character
Unicode Version 17.0
ɑ
U+0251 "ɑ" Latin Small Letter Alpha is a graphic symbol that represents the Latin script equivalent of the Greek alpha, though it is visually distinct from the Latin "a" with its typically single-story, rounded shape. This character is used in the International Phonetic Alphabet to denote the open back unrounded vowel sound, as heard in the English word "father" or the French word "pâte". It is encoded in the Unicode standard as part of the Latin Extended-B block and is often confused with the lowercase Greek alpha or the Latin letter "a", but serves a specific phonetic purpose in linguistics for transcription and study of spoken language.
