The edge of a raised sidewalk or pavement, usually running along the side of a street (primarily British spelling).
From Old French 'courbe' meaning 'curved,' derived from Latin 'curvus.' The word referred to the curved edge of stones or barriers lining streets.
Americans spell it 'curb' while the British say 'kerb,' but they're the same thing—it's one of those spelling differences that makes English wonderfully messy!
