Other forms: concubines
A concubine is a woman living with a man of higher rank without marriage. The king's concubine, kept as a concubine, wives and concubines.
It is a historical and legal term rather than a description anybody uses now: in several ancient societies concubinage was a recognised status, below a wife but above a servant, and the children's rights depended on it. It appears throughout the Bible and in histories of imperial China and Rome. Note concubinage; and that the word names a position in a household rather than a relationship.
