U+1D90 "ᶐ" Latin Small Letter Alpha with Retroflex Hook Unicode Character

Unicode Version 17.0

U+1D90 "ᶐ" Latin Small Letter Alpha with Retroflex Hook is a specialized phonetic symbol used primarily in linguistics to represent a retroflexed version of the alpha vowel sound, typically in the context of the International Phonetic Alphabet (IPA) or its extensions. This character combines the standard Latin small letter alpha, which itself denotes an open back unrounded vowel, with a retroflex hook attached to its lower right, indicating that the tongue tip is curled back during articulation. It is often utilized in the transcription of languages or dialects where such retroflex vowel sounds occur, such as in certain Dravidian or Slavic languages, though it is not part of the core IPA set and may appear in precise phonetic documentation or historical orthographies.
