Chi (hiragana: ã¡, katakana: ãÂÂ) is one of the Japanese kana, which each represent one mora. Both are phonemically , reflected in the Nihon-shiki and Kunrei-shiki romanization ti, although, for phonological reasons, the actual pronunciation is , which is reflected in the Hepburn romanization chi.
The kanji for one thousand (Ã¥ÂÂ, sen), appears similar to ãÂÂ, and at one time they were related, but today ã is used as phonetic, while the kanji carries an entirely unrelated meaning.
Many onomatopoeic words beginning with ã¡ pertain to things that are small or quick.
The dakuten forms ã¢, ãÂÂ, are uncommon. They are primarily used for indicating a voiced consonant in the middle of a compound word (see rendaku), and they don't usually begin a word. The dakuten form of the shi character is sometimes used when transliterating "di", as opposed to ãÂÂ's dakuten form; for example, Aladdin is written as ã¢ã©ã¸ã³ Arajin, and radio is written as ã©ã¸ãª. It is, however, more common to use ãÂÂ㣠instead, such as ãÂÂã£ãªã³ to translate the name Dion.
In the Ainu language, ã by itself is pronounced , and can be combined with the katakana ã¤, ã¦, ã¨, and 㨠to write the other sounds. The combination ãÂÂã§ (pronounced ), is interchangeable with ãÂȋÂÂ.
