n.妾；姨太太；情婦；妃子

The sultan's wives and concubines live in the harem. 蘇丹的妻妾住在后宮。

The legal status of a concubine has varied in different societies. 在不同的社會(huì)，妾的法律地位有所不同。

I'd say she is a concubine's daughter. 我猜是小老婆的女兒罷。

For a maid to become a concubine is quite common-at least it used to be so. 丫頭收房做姨太太，是很普通－－至少在以前很普通的事；
