Biology
early 19th century: coined in German, via French from Greek bios ‘life’ + -logy.
wiktionary
A classical compound (modern coinage), with components derived from Ancient Greek βίος(bíos, “bio-, life”) + -λογία(-logía, “-logy, branch of study, to speak”). The sibling cognates came into various European languages c. 1800 from a New Latin coinage biologia; the term *βιολογία(*biología) did not exist in Ancient Greek (Greek βιολογία(viología) itself is borrowed from both English and French biologie). Since the advent of the scientific era, reanalyzable as a compound using the combining forms bio- + -logy.
etymonline
biology (n.)
"the science of life and living things," 1819, from Greek bios "life, one's life, lifetime" (from PIE root *gwei- "to live;" see bio-) + -logy "study of." Suggested 1802 by German naturalist Gottfried Reinhold Treviranus, and introduced as a scientific term that year in French by Lamarck; they seem to have hit upon the word independently.
