Japanese Hiragana
Hiragana syllables developed from Chinese characters, as shown below. Hiragana were originally called onnade or 'women's hand' as were used mainly by women - men wrote in kanji and katakana. By the 10th century, hiragana were used by everybody. The word hiragana means "oridinary syllabic script".
In early versions of hiragana there were often many different characters to represent the same syllable, however the system was eventually simplified so that there was a one-to-one relationship between spoken and written syllables. The present orthography of hiragana was codified by the Japanese government in 1946.
