Bi

Symbol, Chemistry
1.
bismuth.

bi-1

1.
a combining form meaning “twice,” “two,” used in the formation of compound words:
bifacial; bifarious.
Compare bin-.
Origin
< Latin, combining form of bis; see twice
Usage note
All words except biennial referring to periods of time and prefixed by bi-1 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).

bi-2

1.
variant of bio-, especially before a vowel:
biopsy.
