biologic

The word 'biologic' is a modern scientific formation built directly from classical Greek roots. The first element, bio-, originates from the Greek bios, meaning "life" or "mode of life." The second element, -log-, derives from logos, a term with a rich semantic field encompassing "word," "reason," and "discourse." When combined, -logy came to signify "the study of" a particular subject. The adjectival suffix -ic, of Greco-Latin origin, is then appended to form a word meaning "pertaining to the study of life." Thus, the term's logic follows a clear path from its constituent parts—life + study + pertaining to—to its contemporary meaning relating to the science of living organisms or products derived from them.
