Etymology

anaerobic = an<without> + aero<air> + bic<adjective suffix>

  • an (Greek an-): A prefix meaning "without" or "not."
  • aero (Greek aēr): Refers to "air" or "oxygen."
  • bic (Latin -icus): An adjective-forming suffix indicating relation or pertaining to.

Etymology Origin:
The word "anaerobic" originates from Greek components. The prefix an- negates the root aero- (air/oxygen), combined with the suffix -bic to form an adjective. It was coined in the 19th century to describe biological processes (e.g., fermentation) that occur without oxygen, contrasting with aerobic (oxygen-dependent). The term reflects scientific classification of metabolic pathways.
