Chi (kana)

chi
hiragana katakana
transliteration	chi, ti
translit. with dakuten	ji, zi, di
hiragana origin	知
katakana origin	千
spelling kana	千鳥のチ (Chidori no "chi")

ち, in hiragana, or チ in katakana, is one of the Japanese kana, which each represent one mora. Both are phonemically /ti/ although for phonological reasons, the actual pronunciation is [t͡ɕi].

The kanji for one thousand (千, sen), appears similar to チ, and at one time they were related, but today チ is used as phonetic, while the kanji carries an entirely unrelated meaning.

Many onomatopoeic words beginning with ち pertain to things that are small or quick.^[1]

The dakuten forms ぢ, ヂ, pronounced the same as the dakuten forms of the shi kana in most dialects (see yotsugana), are uncommon. They are primarily used for indicating a voiced consonant in the middle of a compound word (see rendaku), and they can never begin a word, although some people will write the word for hemorrhoids (normally じ) as ぢ for emphasis. Additionally, the dakuten form of the shi character is sometimes used when transliterating "di", as opposed to チ's dakuten form; for example, Aladdin is written as アラジン Arajin, and radio is written as ラジオ.

In the Ainu language, チ by itself is pronounced [t͡ʃi], and can be combined with the katakana ヤ, ユ, エ, and ヨ to write the other [t͡ʃ] sounds as well as [t͡s] sounds. The combination チェ (pronounced [t͡se]), is interchangeable with セ゚.
