U+31F1 "ㇱ" Katakana Letter Small Si Unicode Character

Unicode Version 17.0

U+31F1 "ㇱ" Katakana Letter Small Si is a small form of the standard katakana character シ (si/ shi), used primarily in the Japanese writing system to represent a contracted or abbreviated sound within certain phonetic contexts, particularly in the transcription of foreign languages or in linguistic notation where it indicates a reduced or nonstandard pronunciation. It belongs to the Katakana Phonetic Extensions block, which includes small and modified kana characters that extend the basic katakana set to accurately represent sounds not native to Japanese, such as those found in loanwords from other languages. This small si character helps denote a quicker or less distinct articulation of the "shi" sound, often appearing in specialized dictionaries, educational materials, or phonetic texts to show subtle distinctions in speech without altering the overall meaning of a word.
