'uproar' originates from English, specifically a compound of 'up' + 'roar', where 'up' meant 'up' or 'upwards' and 'roar' meant 'a loud cry or noise'.

'uproar' developed as a compound (written as 'up-roar' or 'up roar') in Early Modern English (late 16th to 17th century) and eventually became the single word 'uproar' in modern English.

Initially, it referred primarily to a literal loud noise or commotion, but over time it also came to be used for figurative public outcry or widespread protest.
