A malapropism is the incorrect use of a word in place of a word with a similar sound, either unintentionally or for comedic effect, resulting in a nonsensical, often humorous utterance. An example is the statement attributed to baseball player Yogi Berra, regarding switch hitters, "He hits from both sides of the plate. He's amphibious", with the accidental use of amphibious rather than the intended ambidextrous. Malapropisms often occur as errors in natural speech and are sometimes the subject of media attention, especially when made by politicians or other prominent individuals. Philosopher Donald Davidson has said that malapropisms show the complex process through which the brain translates thoughts into language.

Lawrence Peter "Yogi" Berra was an American professional baseball catcher who later took on the roles of manager and coach. He played 19 seasons in Major League Baseball (MLB), all but the last for the New York Yankees. He was an 18-time All-Star and won 10 World Series championships as a player—more than any other player in MLB history. Berra had a career batting average of .285, while hitting 358 home runs and 1,430 runs batted in. He is one of only six players to win the American League Most Valuable Player Award three times. He is widely regarded as one of the greatest catchers in baseball history and was elected to the Baseball Hall of Fame in 1972.
