kerb

 
Pronunciation: /kəːb/
(US curb)

noun

  • a stone edging to a pavement or raised path.

Origin:

mid 17th century (denoting a raised border or frame): variant of curb

Do not confuse curb with kerb. Curb means 'control or limit something' ( she promised to curb her temper) or 'a thing that controls or limits', whereas kerb means 'the stone edging of a pavement' (the spelling curb in this sense is American).
