son-in-law
UK: ˈsʌn ɪn lɔː | US: ˈsʌn ɪn lɔː
n. the husband of one’s child
The term "son-in-law" originates from Old English, combining "son" (male child) with "in" (indicating relationship) and "law" (referring to legal or formal ties). Historically, it reflects the societal emphasis on marital bonds as legal affiliations rather than blood relations. The structure parallels other kinship terms like "father-in-law," showcasing English’s pattern of defining familial connections through contractual or social frameworks.
