British vs American spelling
This checker uses the British English dictionary, so it accepts UK spellings and flags American ones when they appear in British text. The most common differences:
| British English | American English | Pattern |
|---|---|---|
| colour, favour | color, favor | -our vs -or |
| organise, realise | organize, realize | -ise vs -ize |
| centre, metre | center, meter | -re vs -er |
| travelled, cancelled | traveled, canceled | double L |
| defence, licence (noun) | defense, license | -ce vs -se |
| analyse | analyze | -yse vs -yze |
Note that -ize spellings like “organize” are also accepted in some British publishing styles, such as Oxford spelling. What matters most is being consistent.
