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
