bi-, bin-, bino-, bis- (Latin: two, twice, double, twofold; a number used as a prefix).This bi- is used before s, c, or a vowel. Don't confuse this bi- with another one that means "life".All words except biennial referring to periods of time and prefixed by bi- are potentially ambiguous. Since bi- can be taken to mean either "twice each" or "every two", a word like biweekly can be understood as "twice each week" or "every two weeks". To avoid confusion, it is better to use the prefix semi- to mean "twice each" (semiannual; semimonthly; semiweekly) or the phrase "twice a" or "twice each "(twice a month; twice a week; twice each year), and for the other sense to use the phrase every two (every two months; every two weeks; every two years). biangular:
