What is art? Marcel Duchamp made this question pertinent when he developed his ‘Readymades’: ordinary, manufactured objects that he presented as art. In this paper, I use pragmatics – the branch of linguistics concerned with language use in context, and which has its historical roots in the philosophy of language – to argue that, if we accept that art is a form of communication, from artist to audience, then Duchamp was correct to claim that anything can be art, so long as it is presented as such.
