チ (romaji chi)
- The katakana syllable チ (chi). Its equivalent in hiragana is ち (chi). It is the seventeenth syllable in the gojūon order; its position is タ行イ段 (ta-gyō i-dan, “row ta, section i”).
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. Names of Japanese companies, as well as certain Japanese language words, are also sometimes written in katakana rather than the other systems.
