A (kana)

A (hiragana: あ, katakana: ア) is one of the Japanese kana that each represent one mora. あ is based on the sōsho style of kanji , and ア is from the radical of kanji . In the modern Japanese system of alphabetical order, it occupies the first position of the alphabet, before い. Additionally, it is the 36th letter in Iroha, after て, before さ. Its hiragana resembles the kana no combined with a cross. The Unicode for あ is U+3042, and the Unicode for ア is U+30A2.

Derivation

The katakana ア derives, via man'yōgana, from the left element of kanji . The hiragana あ derives from cursive simplification of the kanji .

Variant forms

Scaled-down versions of the kana (ぁ, ァ) are used to express sounds foreign to the Japanese language, such as ファ (fa). In some Okinawan writing systems, a small ぁ is also combined with the kana く (ku) and ふ (fu or hu) to form the digraphs くぁ kwa and ふぁ hwa, although others use a small ゎ instead. In hentaigana, a variant of あ is appeared with a stroke written exactly as wakanmuri.
