Late 17th century (denoting a trick or hoax): from obsolete fun 'to cheat or hoax', dialect variant of late Middle English fon 'make a fool of, be a fool', related to fon 'a fool', of unknown origin. Compare with fond.

  • The earliest sense of this surprisingly recent word is ‘trick’ or ‘hoax. It seems to come ultimately from a dialect pronunciation of Middle English fon ‘a fool’ ( see fond). Our current sense dates only from the 18th century, and in 1755 Dr Johnson described it disapprovingly as ‘a low cant [slang] word’. He would probably have sympathized with the view given in the humorist A. P. Herbert's Uncommon Law (1935): ‘People must not have fun. We are not here for fun. There is no reference to fun in any Act of Parliament.’ Things can be funny (mid 18th century) in several different ways. The expressions funny ha-ha and funny peculiar, encapsulating the distinctions in meaning between what is amusing and what is strange, were coined by the writer Ian Hay in his novel The Housemaster (1936). Funny money dates from the 1930s when it was used in the US for forged money.
