Shoujo

Shōjo, shojo or shoujo (, ^?) is a Japanese word for "girl".

The word is originally derived from a Chinese expression written with the same characters. The Chinese characters (少 and 女) literally mean young/little and woman respectively. In Japanese, these kanji refer specifically to a young woman approximately 7–18 years old.

Like most kanji compounds, the term shōjo is borrowed from Classical Chinese characters. The original term is written as "少女", which could be pronounced as shào nǚ in Mandarin (pinyin romanization), so nyŏ in Korean (McCune-Reischauer romanization), thiếu nữ in Vietnamese, and shōjo in Japanese (Hepburn romanization).

The earliest surviving written record of the term 少女 is on the Book of the Later Han, published in China in the 5th century, in Chapter 86, The myth of Yao, referring to young girls.

盤瓠種，昔帝嚳時患犬戎入寇, 乃訪募天下，有能得犬戎之將吳將軍頭者，購黃金千鎰，邑萬家，又妻以少女.

Translation: The myth of Yao: the country is being invaded by barbarians, the king is looking for warriors who are capable of taking the head of the general of the invading army, and for this the king will award (a) thousand Yi of gold, (a) myriad of houses and young girl(s) as their wife/wives.
