bi-

1
a combining form meaning “twice,” “two,” used in the formation of compound words: bifacial; bifarious.
Compare bin-.


Origin:
< L, comb. form of bis; see twice


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
var. of bio-, esp. before a vowel: biopsy.

bio-

a combining form meaning “life” occurring in loanwords from Greek (biography); on this model, used in the formation of compound words (bioluminescence).
Also, especially before a vowel, bi-.


Origin:
comb. form of Gk bíos life; akin to L vīvus living, Skt jīvas. See quick

Word Origin & History

bi- 
"two, twice," etc., from L. bi-, from Old L. dvi- (cognate of Gk. di-, O.E. twi-).

bio- 
from Gk. bio-, comb. form of bios "life, course or way of living" (as opposed to zoe "animal life, organic life"), from PIE base *gweie- "to live" (cf. Skt. jivah "alive, living;" O.E. cwic "alive;" L. vivus "living, alive," vita "life;" M.Pers. zhiwak "alive;" O.C.S. zivo "to live;" Lith. gyvas "living, alive;" O.Ir. bethu "life," bith "age;" Welsh byd "world"). The correct usage is that in biography, but in modern science it has been extended to mean "organic life."

bi

in art, Chinese jade carved in the form of a flat disk with a hole in the centre. The earliest examples, which are unornamented, date from the Neolithic Period (c. 5000-2000 BC). Later examples, from the Shang (18th-12th century BC) and Zhou dynasties (1111-256/255 BC), have increasingly elaborate surface embellishment, especially in the late Zhou (c. 600-256/255 BC), when the bi appeared in combination with other forms
