Small form of the katakana character ヨ (yo).
- Small combining form of katakana ヨ (yo) used in 拗音 (yōon) morae that end in o, such as ショ (sho), チョ (cho), and キョ (kyo). Historically not distinguished from full-size version.
Unlike the hiragana system, used for Japanese language words that kanji does not cover, the katakana syllabary is used primarily for transcription of foreign language words into Japanese and the writing of loan words (collectively gairaigo), as well as to represent onomatopoeias, technical and scientific terms, and the names of plants, animals, and minerals. It is also occasionally used colloquially in some words for emphasis. Names of Japanese companies, as well as certain Japanese language words, are also sometimes written in katakana rather than the other systems. Formerly, female given names were written in katakana.
