Pronunciation

Etymology

It is borrowed from New Latin bio-,[2][3] from Ancient Greek βίο- (bío-), the combining form of βίος (bíos, “life, way of living”),[2][4][5][3][6] as opposed to ζωή (zōḗ, “animal life, organic life”).[2][4] The OED says the word probably comes ultimately from the same Indo-European base as quick.[2][5][3] Etymonline and Barnhart give this as Proto-Indo-European *gʷei- (“to live”).[4][3] It is cognate with Latin vīvus (“living”).[3]

Earliest recorded meaning

English first has it in borrowings and adaptations of Latin words from the 17th century, in biotic and in biography and its family.[2][5] The meaning there is the course of a person's life.[4][6]

Semantic evolution

Etymonline calls the use in biography the correct one, and notes that from about 1800 modern science extended it to organic life, a job for which zoo- would have been a better fit, were that not now restricted to animals.[4] French and German had formations by the early 19th century too, and those within English begin at the same time, with biometer and bioscope.[2] Weekley records biograph and bioscope as early names for the cinematograph.[7] biology itself is older than these, and it gave the sense of biological, as in biochemistry.[2][3] In the 20th century the prefix became very productive for words about biotechnology and the environment, some of them temporary, while words such as biopic keep the biographical sense.[2][6]
