daughter-in-law
UK: ˈdɔːtər ɪn lɔː | US: ˈdɔːtər ɪn lɔː
n. the wife of one’s son or daughter
The term "daughter-in-law" originates from Old English dohtor (daughter) combined with in (a preposition denoting relationship) and lagu (law, here meaning "custom" or "bond"). Historically, it reflected the legal and social bond formed through marriage, where a woman became part of her spouse’s family under customary law. The structure emphasizes the relational hierarchy ("daughter by legal tie") rather than blood relation.
