U+31F0 "ㇰ" Katakana Letter Small Ku Unicode Character

Unicode Version 17.0

U+31F0 "ㇰ" Katakana Letter Small Ku is a specialized phonetic symbol used in the Japanese writing system, specifically within the Katakana block of Unicode. Unlike the standard full-sized katakana character "ク" (ku), this smaller version is employed to represent a shortened or more subtle pronunciation of the "ku" sound, often appearing in combination with other characters to transcribe foreign loanwords, dialects, or nuanced phonetic shifts that cannot be captured by regular sized kana. Its diminutive form signals that the syllable is not fully pronounced, similar to how small "ya," "yu," and "yo" are used to create compound sounds, though "ㇰ" specifically modifies the preceding consonant sound rather than forming a palatalized syllable. This character is part of a set of small katakana letters designed to accurately represent sounds from other languages, particularly in modern Japanese transliterations of words from Ainu, Taiwanese, or other regional languages.
