Word History

Etymology

borrowed from New Latin imāgō, going back to Latin imāgin-, imāgō "representation, semblance, image entry 1"

Note: As a descriptive term for insects apparently introduced by linnaeus in Systema naturae, 12th edition, vol. 1, part 2 (Stockholm, 1767), p. 535. Linnaeus's conception was that the imago was the true representation of the creature, the earlier stages of larva (Latin larva, taken to mean "ghost") and pupa (Latin pūpa "doll") being in a sense illusory.
