American vs British English
American and British English share most vocabulary and grammar, but they differ in spelling, word choice, and some usage patterns. Because Word Choice Lab primarily serves a US audience, these guides identify the standard American form while explaining important British alternatives.
This category covers pairs such as color/colour, favorite/favourite, center/centre, theater/theatre, traveler/traveller, organize/organise, realize/realise, defense/defence, license/licence, and practice/practise.
Use this archive when writing for a US audience, editing international English, or checking whether a spelling difference is regional rather than wrong. The main rule is consistency: choose American or British style and use it throughout the document.
