bio- \bi"o-\ pref. a prefix meaning of or pertaining to life, produced by living things, etc.

Douglas Harper's Etymology Dictionary

word-forming element, from Greek bio-, comb. form of bios "one's life, course or way of living, lifetime" (as opposed to zoe "animal life, organic life"), from PIE root *gweie- (1) "to live" (cognates: Sanskrit jivah "alive, living;" Old Persian *jivaka- "alive," Middle Persian zhiwak "alive;" Old English cwic, cwicu "living, alive;" Latin vivus "living, alive," vita "life;" Old Church Slavonic zivo "to live;" Lithuanian gyvas "living, alive," gyvata "(eternal) life;" Old Irish 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."


pre. 1 life 2 organic life
