あ in Hiragana and ア in katakana - symbols of Japanese kana, used for writing exactly one mora (unit of longitude of foot). It matches cyrillic "а". In modern Japanese syllabary it is the first letter, after it goes い.
The originEditThe character あ appeared within simplified spelling of kanji 安. And ア came from the original kanji.
Order of linesEdit
The hirigana character "あ" is written with 3 lines:
1. first, a horizontal line is written left to right
2. then, a vertical line, passing through the middle, is written downwards
3. the last line is written in the bottom part, by parity of reasoning with "の".
