Harbor or Harbour – Quick Answer
The difference is simple:
- Harbor → Used in American English
- Harbour → Used in British English
Both words mean the same thing. A harbor/harbour is a sheltered place where ships dock.
Examples:
- The ship entered the harbor. (US)
- The ship entered the harbour. (UK)
The meaning does not change. Only the spelling does.
The Origin of Harbor or Harbour
The word comes from Old English “herebeorg.” It meant shelter or protection. Over time, it evolved into harbour in Middle English.
When English spread across countries, spelling began to change. In the 1800s, American English simplified many British spellings. The man behind many changes was Noah Webster.
Webster believed spelling should match pronunciation. He removed extra letters like “u” in words such as:
- colour → color
- honour → honor
- harbour → harbor
That is why Americans write harbor, while British English kept harbour.
British English vs American English Spelling
The difference between harbor and harbour follows a clear rule.
In British English, many words end in -our.
In American English, the same words drop the u and become -or.
