Ordinary language philosophy (OLP, sometimes called linguistic philosophy) is a methodological approach within analytic philosophy which treats many traditional philosophical problems as the result of misunderstandings of how words are ordinarily used. Rather than proposing ideal or artificial languages, ordinary language philosophers investigate the actual use of expressions in everyday contexts, and often argue that once such uses are described carefully, many philosophical "problems" dissolve or change their shape.
In the twentieth century OLP was primarily associated with the later work of Ludwig Wittgenstein, early to mid-century philosophers at the University of Cambridge such as G. E. Moore and John Wisdom, and mid-century philosophers at the University of Oxford, including Gilbert Ryle, J. L. Austin, P. F. Strawson, H. L. A. Hart, and Paul Grice. Because a number of its most prominent practitioners taught at Oxford, OLP is sometimes informally referred to as "Oxford philosophy".
