Why is the ninth month called September?
late 15c., from Middle French nuptial, or directly from Latin nuptialis "pertaining to marriage," from nuptiae "wedding," from nupta, fem. past participle of nubere "to marry, wed, take as a husband," related to Greek nymphe "bride," from PIE *sneubh- "to marry, wed" (cf. Old Church Slavonic snubiti "to love, woo," Czech snoubiti "to seek in marriage," Slovak zasnubit "to betroth"). Related: Nuptially.
