The Cyclopedic Law Dictionary
A woman who cohabits with a man as his wife without being married. When a single woman consents unlawfully to cohabit with a man generally, as though the marriage relation existed between them, without any limit as to the duration of such illicit intercourse, and actually commences cohabiting with him in pursuance of that understanding, she becomes his concubine.
