英语词汇bi-weekly的起源、历史背景-英语词源词典

词汇	bi-weekly
词源	bi-weekly adj. also biweekly, 1865, from bi- "two, twice" + weekly. The sense of "twice a week" is the earliest attested, but that of "every two weeks" is equally implied and preferred, the "twice-a-week" meaning going with semi-weekly. Entries linking to bi-weekly bi- word-forming element meaning "two, having two, twice, double, doubly, twofold, once every two," etc., from Latin bi- "twice, double," from Old Latin dvi- (cognate with Sanskrit dvi-, Greek di-, dis-, Old English twi-, German zwei- "twice, double"), from PIE root *dwo- "two." Nativized from 16c. Occasionally bin- before vowels; this form originated in French, not Latin, and might be partly based on or influenced by Latin bini "twofold" (see binary). In chemical terms, it denotes two parts or equivalents of the substance referred to. Cognate with twi- and di- (1). weekly mid-15c. (adv.); late 15c. (adj.), from week + -ly (2). As a noun meaning "weekly newspaper" it is recorded from 1833. semi-weekly adj. also semiweekly, "made, issued, or occurring twice a week," 1791, of newspapers, from semi- + weekly. updated on October 13, 2022
