A spoonerism is a mistake made by a speaker in which the first sounds of two words are changed over, often with a humorous result, for example when someone says `wrong load' instead of `long road'. a phrase in which the speaker accidentally exchanges the first sounds of two words, with a funny result, for example 'sew you to a sheet' instead of 'show you to a seat' (William Spooner (1844-1930), British university teacher who supposedly often made such mistakes). Reversal of the initial letters or syllables of two or more words, such as "I have a half-warmed fish in my mind" (for "half-formed wish") and "a blushing crow" ("a crushing blow"). The word is derived from the name of William Archibald Spooner (1844-1930), a distinguished Anglican clergyman and warden of New College, Oxford, a nervous man who committed many "spoonerisms." Such transpositions are often made intentionally for comic effect
