U+1D45 "ᵅ" Modifier Letter Small Alpha Unicode Character

Unicode Version 17.0

U+1D45 "ᵅ" Modifier Letter Small Alpha is a superscript or raised version of the Latin small letter alpha, categorized as a modifier letter used primarily in phonetic transcription. It represents a reduced or shortened vowel sound, often employed in the International Phonetic Alphabet or its extensions to indicate a secondary articulation or a weak, fleeting pronunciation of the open back unrounded vowel typically associated with the standard alpha symbol. This character allows linguists and language researchers to precisely denote subtle phonetic variations in speech, such as devoicing, nasalization, or length modifications, without altering the primary vowel symbol. Its inclusion in Unicode ensures consistent digital representation across platforms for scholarly work in phonology and speech science.
