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”).
The katakana syllabary is used primarily for transcription of foreign language words into Japanese and the writing of gairaigo (loan words), as well as to represent onomatopoeias, technical and scientific terms, and the names of plants, animals, and minerals. It is also occasionally used in some words for emphasis, or to ease reading; katakana may be preferred for words becoming buried in the text if they are written under their canonical form in hiragana. Names of Japanese companies, as well as certain Japanese language words such as colloquial terms, are also sometimes written in katakana rather than the other systems. Formerly, female firstnames would often be written in katakana.
