Etymology
the term exogamous is a modern scientific formation built from ancient greek components. it combines the prefix 'exo-', meaning "outside", with the root '-gam-', derived from 'gamos' (marriage), and the adjectival suffix '-ous'. this construction follows a classical pattern where greek roots were adopted into scholarly latin and later into modern scientific english. the literal meaning, "characterized by marriage outside," directly reflects the anthropological and biological concepts it describes, illustrating a continuity where ancient words for social and reproductive unions are repurposed to name specific relational patterns in modern science.
