Etymology
The term "daughter-in-law" is a native English compound, its components tracing back to Old English. The word "daughter" originates from Proto-Germanic dōhtēr, itself from the Proto-Indo-European root dhugh₂tḗr. The preposition "in" maintains its common function. The most significant semantic shift is found in "law," which derives from Old Norse lagu, meaning "something laid down or fixed." In the context of family relations, "in-law" originally denoted a connection established by canonical or legal decree, as opposed to blood. Thus, the compound literally means "a daughter by legal decree," succinctly capturing the marital bond that creates the relationship.
Analysis
This is a compound noun formed from three English words: "daughter" (from Old English 'dohtor', meaning female child), the preposition "in", and the noun "law" (from Old English 'lagu', meaning rule, ordinance). In this compound, "law" takes on an archaic meaning of "relationship by marriage."
