Etymology

The word "biological" combines three morphemes:

  • "Bio" (from Greek bios, meaning "life")
  • "Log" (from Greek logos, meaning "study" or "discourse")
  • "Ical" (a suffix forming adjectives, indicating "pertaining to")
    Originally used in scientific contexts, it evolved to broadly describe anything related to living organisms or life processes. The term reflects the logical structure of scientific classification, where "bio-" anchors the domain of life and "-logy" denotes systematic study.
