What does kerb mean?
A kerb is the raised edge of a road or pavement, separating the trafficway from the pedestrian area and often marking where vehicles may stop or park. The word is especially associated with British English, whereas American English generally uses “curb” for the same feature. In everyday use, “kerb” can refer to the physical boundary itself, but it can also describe a location beside the road, as in “at the kerb” or “kerbside.” Related expressions include “kerbside collection” for services that collect waste from the edge of a pavement, “mount the kerb” for driving or riding onto a raised edge, and “park by the kerb.” Although the word is simple and familiar, it describes a small but important feature of street design, with practical effects on drainage, parking, accessibility, and pedestrian safety.
The raised edge or border of a road, pavement, or other paved surface.
"The car mounted the kerb outside the shop."
The British spelling is standard in British English; American English normally uses “curb.”

Where does kerb come from?
The word entered Middle English in the form “curb,” which was related to Old French “curb” and ultimately to a word for a restraint or barrier. The spelling with “k” became established in British English, while the spelling with “c” remained standard in American English. The sense developed from the idea of a raised edge or boundary, related to the modern meaning of “curb” as a restraint on behaviour or movement.
