bi-

bi- |bʌɪ |(often bin- before a vowel ) ▶comb. form two; having two: bicolored | biathlon | binocular. • occurring twice in every one: biannual | bimonthly. • occurring once in every two: bicentennial | biennial. • lasting for two: biennial | biennium. • doubly; in two ways: biconcave. • Chemistry a substance having a double proportion of the radical, group, etc. , indicated by the simple word: bicarbonate | binoxalate. • Botany & Zoology (of division and subdivision ) twice over: bipinnate. ORIGIN from Latin, earlier dui-, related to Greek di- ‘two ’ and Sanskrit dvi- ‘doubly, having two. ’ usage: The meaning of bimonthly (and other similar words such as biweekly and biyearly ) is ambiguous. Bimonthly, for instance, can mean either ‘occurring or produced twice a month ’ or ‘occurring or produced every two months.’ So, if an organization holds bimonthly meetings, over the course of a year, will it meet six times or twenty-four times? The only way to avoid this ambiguity is to use alternative expressions like every two months and twice a month. See also usage at biennial .
