Sense: noun/1
Camber, crown, slope, and gradient all describe angled surfaces, but they differ in what they measure. Camber specifically refers to the sideways curve of a road that is higher in the middle and lower at the edges — its purpose is drainage, not direction. Crown is very close in meaning but names the high point itself (the 'top' of the camber) rather than the full curved shape. Slope is a general term for any surface that is not level; it can describe hills, ramps, or tilted floors. Gradient describes how steep a road is along its length (going up or down a hill), not across its width. For example, 'The road has a good camber so water runs off,' but 'The gradient of that hill is one in ten.' If someone says 'the crown of the road,' they are talking about the highest point; 'camber' covers the entire cross-section shape.

Etymology
The word 'camber' entered English in the 1500s from Old French 'cambre' (meaning 'curved'), which came from Latin 'camerare' ('to arch'), related to 'camera' ('a vaulted room'). The sense of a curved road surface developed in the 1700s as road-building techniques improved. The automotive wheel-angle meaning appeared in the early 1900s alongside the rise of the automobile.
