U+1D53 "ᵓ" Modifier Letter Small Open O Unicode Character

Unicode Version 17.0

U+1D53 "ᵓ" Modifier Letter Small Open O is a specialized typographic symbol used primarily in phonetic transcription to indicate a modified or reduced quality of the open o vowel sound, often employed in extensions of the International Phonetic Alphabet or in certain linguistic diacritic systems. As a superscript form of the lowercase open o, it functions as a modifier to preceding or following letters to denote subtle variations in articulation, such as a lower, more open, or less rounded pronunciation. This character belongs to the Unicode block for phonetic extensions, reflecting its role in precise linguistic notation rather than in standard alphabetic writing. Its inclusion in digital text supports accurate representation of speech sounds in scholarly works, language documentation, and linguistic data processing.
