Etymologies
- From the name of Mrs. Malaprop, a character in the play The Rivals (1775) by Richard Brinsley Sheridan + -ism. As dramatic characters in English comic plays of this time often had allusive names, it is likely that Sheridan fashioned the name from malapropos ("inappropriate"). Mrs. Malaprop is perhaps the best-known example of a familiar comedic character archetype who unintentionally substitutes inappropriate but like-sounding words that take on a ludicrous meaning when used incorrectly. (Wiktionary)
- From malaprop. (American Heritage® Dictionary of the English Language, Fourth Edition)

PossibleUnderscore Bottom, from A Midsummer Night's Dream is famous for numerous amusing malapropisms. Jul 26, 2009
ecbrenner "Malapropisms are words that, because they are used incorrectly, produce a humorous effect. The term derives from the character Mrs. Malaprop in Richard Brinsley Sheridan's play 'The Rivals' (1775). Mrs. Malaprop loves big words, but she uses them ignorantly to create hilarious solecisms and occasionally embarrassing double entendres. One of Mrs. Malaprop's famous similes is 'as headstrong as an allegory on the banks of the Nile.' -- Bryan A. Garner, Garner's Modern American Usage Jan 29, 2009
