A spoonerism is an error in speech in which corresponding consonants, vowels, or morphemes are switched (see metathesis) between two words in a phrase. These are named after the Oxford don and ordained minister William Archibald Spooner, who reputedly did this. They were already renowned by the author François Rabelais in the 16th century, and called contrepèteries. In his novel Pantagruel, he wrote “femme folle à la messe et femme molle à la fesse” ("insane woman at mass, woman with flabby buttocks").
