| Behavior | Behaviour |
Because both spellings appear frequently online, many writers assume one must be incorrect.

This difference comes from broader spelling patterns between American and British English.

British English:
- colour
- favour
- honour
- behaviour
The spelling system is intentional rather than random.
Why Does American English Use “Color”?
The American spelling developed during language standardization efforts in the United States.
Lexicographer Noah Webster promoted spelling reforms in the late 1700s and early 1800s to simplify English spelling and create a distinct American writing system.
Words ending in “-our” often became “-or” in American English.
Examples:
- colour → color
- favour → favor
- labour → labor
- neighbour → neighbor
British English kept the older spelling pattern.
Over time, both systems became standard within their regions.
