Appropriation is a fundamental aspect in the history of the arts (literary, visual, musical). Appropriation can be understood as "the use of borrowed elements in the creation of a new work."
In the visual arts, to appropriate means to properly adopt, borrow, recycle or sample aspects (or the entire form) of man-made visual culture. Strategies include "re-vision, re-evaluation, variation, version, interpretation, imitation, proximation, supplement, increment, improvisation, prequel... pastiche, paraphrase, parody, homage, mimicry, shan-zhai, echo, allusion, intertextuality and karaoke." The term appropriation refers to the use of borrowed elements in the creation of a new work (as in 'the artist uses appropriation') or refers to the new work itself (as in 'this is a piece of appropriation art').
Inherent in our understanding of appropriation is the concept that the new work recontextualises whatever it borrows to create the new work. In most cases the original 'thing' remains accessible as the original, without change.
