'clamorous' originates from Latin, specifically the word 'clamorosus,' where 'clamor' meant 'shout' or 'cry.'

'clamorosus' transformed into the Old French word 'clamoreux,' and eventually became the modern English word 'clamorous' through Middle English.

Initially, it meant 'full of shouting or noise,' but over time it evolved into its current meaning of 'making a loud and confused noise.'
