'gibberish' originates from the English word 'gibber,' which is an imitation of the sound of rapid, unintelligible speech.

'gibber' transformed into 'gibberish' in the 16th century, eventually becoming the modern English word 'gibberish'.

Initially, it meant 'rapid, unintelligible speech,' and over time it evolved into its current meaning of 'nonsensical talk or writing'.
