Spoonerisms swap the opening sounds of neighboring words, which can turn a serious phrase into an accidental joke.

The longer version

Speech planning assembles the first consonant of each word in advance, and sometimes two of those onsets trade places: crushing blow comes out as blushing crow. The swap happens before the sentence is spoken, which is why the mistake respects the rhythm and grammar of what was intended.

The pattern is named after a nineteenth-century clergyman remembered for such slips, though most of the famous examples attributed to him were probably invented by students. Unlike a wrong-word error, the vocabulary here is right and only the sounds move. Speech-error research treats these slips as evidence that the brain prepares several words ahead of the voice.
