Bushisms are unconventional statements, phrases, pronunciations, malapropisms, and semantic or linguistic errors made in the public speaking of George W. Bush, the 43rd President of the United States. Common characteristics of Bushisms include malapropisms, spoonerisms, the creation of neologisms or stunt words, and errors in subject–verb agreement.

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.
