Plural of clamour; loud, insistent demands, complaints, or confusing noises from many people.
From Old French 'clamor' through Middle English 'clamour.' In British English, this spelling (rather than American 'clamors') preserves the French '-our' ending that marks words of Romance origin.
The spelling difference between British 'clamours' and American 'clamors' traces back to Noah Webster's deliberate simplification campaign in 1828—he wanted to 'Americanize' English by removing 'unnecessary' letters.
