Etymology

inimical = in<not> + imic<friend> + al<adjective suffix>

  • in- (Latin prefix): Negation, meaning "not."
  • imic (from Latin amicus): Meaning "friend."
  • -al (Latin suffix): Forms adjectives indicating relation or quality.

Etymology Origin:
Derived from Latin inimicus ("enemy"), itself formed from in- (not) + amicus (friend). The word evolved through Late Latin and Middle English, retaining its core sense of hostility. The morpheme imic preserves the Latin root amicus, though the spelling shifted slightly in English. The logic is straightforward: "not a friend" → "hostile."
