Words: Malapropism

I'm sure you know what a malapropism is, and that it derives from the character Mrs. Malaprop in "The Rivals" by Richard Brinsley Sheridan. But I didn't know until recently that Richard stole the character from his mother, Frances Chamberlaine Sheridan. Her play, "A Trip To Bath", has a character called Mrs. Tryfort who also mangles the English language.
