Word Origin & History
brideO.E. bryd "bride, betrothed or newly married woman," from P.Gmc. *bruthiz "woman being married" (cf. O.Fris. breid, Du. bruid, O.H.G. brut, Ger. Braut "bride"). Goth. cognate bruþs, however, meant "daughter-in-law," and the form of the word borrowed from O.H.G. into M.L. (bruta) and O.Fr. (bruy)
only had this sense. In ancient IE custom, the married woman went to live with her husband's family, so the only "newly wed female" in such a household would be the daughter-in-law. On the same notion, some trace the word itself to the PIE verbal root *bru- "to cook, brew, make broth," as this was the daughter-in-law's job.
