"This book demonstrates the extent and importance of language play in human life, considering it at the formal level (as the patterning of sound and structure), at the semantic level (as the creation of fictions and fantasies), and at the pragmatic level (as humour, social display, and agonistic contest). Far from being seen as a trivial or peripheral activity, language play is depicted as central to human thought, underpinning our capacity to...
