'uproariously' originates from the word 'uproarious,' which is derived from the noun 'uproar,' meaning 'a loud and impassioned noise or disturbance.'

'uproar' changed from the Middle Dutch word 'oproer,' meaning 'a tumult or disturbance,' and eventually became the modern English word 'uproar.'

Initially, it meant 'a loud disturbance,' but over time it evolved into its current meaning of 'causing loud laughter or noise.'
