bride (n.)youdaoicibaDictYouDict[bride 词源字典]
Old English bryd "bride, betrothed or newly married woman," from Proto-Germanic *bruthiz "woman being married" (cognates: Old Frisian breid, Dutch bruid, Old High German brut, German Braut "bride"). Gothic cognate bruþs, however, meant "daughter-in-law," and the form of the word borrowed from Old High German into Medieval Latin (bruta) and Old French (bruy) had only this sense. In ancient Indo-European custom, the married woman went to live with her husband's family, so the only "newly wed female" in such a household would have been 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 likely was the daughter-in-law's job.[bride etymology, bride origin, 英语词源]

Old English dohtor, from Proto-Germanic *dokhter, earlier *dhukter (cognates: Old Saxon dohtar, Old Norse dottir, Old Frisian and Dutch dochter, German Tochter, Gothic dauhtar), from PIE *dhugheter (cognates: Sanskrit duhitar-, Avestan dugeda-, Armenian dustr, Old Church Slavonic dušti, Lithuanian dukte, Greek thygater).

gamete (n.)youdaoicibaDictYouDict
"sexual protoplasmic body," 1880, coined 1878 by German cytologist Eduard Strasburger (1844-1912), the widespread attribution of the word's coinage to Mendel being apparently erroneous. From Greek gamete "a wife," gametes "a husband," from gamein "to take to wife, to marry," from PIE root *gem(e)- "to marry" (cognates: Greek gambros "son-in-law, father-in-law, brother-in-law;" Sanskrit jamih "brother, sister," jama daughter-in-law;" Avestan zama-tar "son-in-law;" Latin gener "son-in-law"). See also -gamy. The seventh month of the ancient Attic calendar (corresponding to late January and early February) was Gamelion, "Month of Marriages." Related: Gametal.
