The word curb has two common meanings in English. In everyday American English, a curb is the raised edge beside a street, usually between the road and the sidewalk. As a verb, curb means to control, limit, or hold something back.
For example, a driver may park near the curb, but a city may try to curb traffic noise. The same spelling works in both sentences, but the meaning changes with context.
This guide explains curb in plain English, including its noun and verb uses, pronunciation, examples, common phrases, spelling tips, and the difference between curb and kerb.
