Origin
Early 20th century: from Greek klōn 'twig'.
The word clone, from Greek klōn ‘twig, cutting from a plant’, is first recorded in 1903, when it referred to a group of plants produced by taking cuttings or grafts from an original. It has been used in the context of the genetic duplication of mammals since the early 1970s. Nowadays it is also used for someone who slavishly imitates someone else and for a computer that simulates another more expensive model. In gay culture a clone is a gay man who adopts an exaggeratedly macho appearance and style of dress.
