Game-Specific Strategies
Check Your Dictionary
Most word games specify which dictionary they use:
- UK games: Usually Collins or Oxford
- US games: Usually Merriam-Webster
- International: Often accept both
When in Doubt
If you're unsure which spelling to use:
1. Try the American spelling first (shorter, often more accepted) 2. If rejected, try British spelling 3. Note which version works for future reference
Both Spellings Exist
Remember that some games accept both:
- COLOUR and COLOR might both work
- This effectively doubles your word options
Common Mistakes to Avoid
False Friends
Some words look like they should vary but don't:
- GLAMOUR is often acceptable in both (not GLAMOR)
- HONOUR in historical/military contexts sometimes kept
- SAVIOUR sometimes kept in religious contexts
Hypercorrection
Don't add -OUR where it doesn't belong:
- ERROR is always ERROR (not ERROUR)
- EMPEROR is always EMPEROR (not EMPEROUR)
-ISE Words That Don't Vary
Some -ISE words are always spelled that way:
- ADVERTISE, ADVISE, COMPRISE, DESPISE, DEVISE, DISGUISE, EXCISE, EXERCISE, IMPROVISE, REVISE, SUPERVISE, SURPRISE
