The English language is full of homophones—words that sound the same but have different spellings and meanings. One such pair that often confuses writers is curb and kerb. While they may sound identical when spoken, their usage and meanings differ, particularly between British and American English.
This blog explores the distinctions between curb and kerb, explains their specific meanings, and provides practical examples to ensure you never mix them up again.
Curb vs Kerb: An Overview
What is Curb?
Curb is the American English spelling and refers to:
- Control or Restraint
As a verb, it means to control or limit something.- Example: We must curb our spending to stay within budget.
- The Edge of a Pavement
As a noun, it describes the raised edge of a pavement or road in American English.- Example: She parked the car next to the curb.
What is Kerb?
Kerb is the British English spelling of the noun referring to the edge of a pavement or road. It is not used as a verb.
- Example: The cyclist hit the kerb and fell off.
In British English, curb is only used to describe control or restraint. Therefore, if you’re writing in British English and describing the edge of a road, kerb is the correct spelling.
How to Spell Curb and Kerb Correctly
The choice between curb and kerb depends on the context and whether you are following British or American spelling conventions.
American English
- Curb is used for both meanings: restraint/control and the edge of a pavement.
- Example: The city council installed new curbs along the street.
British English
- Curb is used for restraint/control.
- Kerb is used exclusively for the edge of a pavement or road.
- Example: The driver narrowly missed the kerb when making the turn.
Understanding regional differences is crucial for ensuring your writing aligns with the expectations of your audience.
Curb as a Verb
Curb as a verb applies universally in both British and American English. It is most often used to describe actions of limiting or restraining.
Examples
- The government is implementing measures to curb inflation.
- She tried to curb her excitement before the results were announced.
The verb form has no equivalent spelling as kerb and is therefore straightforward to use.
Kerb as a Noun in British English
In British English, kerb is exclusively a noun and refers to the edge of a pavement. Its spelling never overlaps with the American usage of curb.
Examples
- Mind the kerb when stepping out of the car.
- The council is repairing damaged kerbs across the city.
This distinction helps maintain clarity in British English writing.
