Modifier Letter Small V at U+1D5B is a superscript-style modifier letter used to add a small v-like phonetic annotation to neighboring text. It belongs to the Phonetic Extensions block, a set of characters largely intended for linguistic transcription rather than ordinary alphabetic spelling. Its main use is in phonetics and phonology, especially in transcriptions where a raised v marks a secondary articulation or a closely timed vocalic or labiodental quality, depending on the transcription convention. You may see it in specialist descriptions of speech sounds beside IPA symbols, where the modifier is part of the analysis rather than a separate pronounced letter. It also appears in linguistic databases, dictionaries, and academic publications that need plain-text phonetic notation instead of styled superscripts. Because it is a distinct modifier letter and not just a formatted lowercase v, searching or normalizing text can treat it differently from an ordinary v or from a visually superscripted character.
