Origin & History of “image”

Latin imāgō meant a ‘likeness of something’ (it probably came from the same source as imitate). It subsequently developed a range of secondary senses, such as ‘echo’ and ‘ghost’, which have not survived the journey via Old French into English, but the central ‘likeness’ remains in place. Derived from the noun in Latin was the verb imāginārī ‘form an image of in one’s mind, picture to oneself’, which became English imagine (14th c.). (Latin imāgō, incidentally, was used in the 1760s by the Swedish naturalist Linnaeus for an ‘adult insect’ – based on the Latin sense ‘natural shape’, the idea being that the insect had achieved its final perfect form after various pupal forms – and English took the term over at the end of the 18th century.).
