Gibber

Gibber is a term used to describe unintelligible or nonsensical speech. It can refer to the sounds a baby makes before they can form coherent words, or it can describe adult speech that is so jumbled or meaningless as to be incomprehensible. In some contexts, gibbering may be associated with excitement, distress, or a lack of understanding. It can also be used humorously to mimic or mock such speech. The exact nature of gibbering can vary widely depending on the individual and the situation. It is often characterized by a rapid succession of sounds, syllables, or words that lack logical connection or grammatical structure. While not a formal linguistic term, "gibber" is a commonly understood word for a specific type of vocalization.
