Gibberish is a form of speech that consists of nonsensical words or sounds, often used for playful or humorous purposes. It can be created by altering real words, mixing syllables, or using made-up terms. People sometimes use gibberish in games, storytelling, or as a way to entertain children. In linguistics, gibberish can also refer to speech that is difficult to understand due to its complexity or lack of coherence. While it is not a formal language, gibberish can serve as a fun way to explore language and communication, often seen in children's literature or improv comedy.
