American English Spelling Words

If you're learning American English — for school, for work in the US, for TOEFL or American-based exams, or because you've settled in the States — the spelling conventions matter. A word written colour or organise is unmistakably British; in an American context, color and organize are what you're expected to write.

This practice test drills 20 everyday American spellings at B1 level. You'll work through the main patterns: -or endings (color, favorite, neighbor), -er endings (center, theater, liter), -ize verbs (organize, realize, apologize), single l in past and -ing forms (traveled, canceled), and a handful of American-only spellings like gray, tire, and program.

Listen to each word, type what you hear in its American form, and get instant feedback. Repeat any word you miss. By the end, your spelling will look unmistakably American — no stray us, no extra ls, no British -re endings slipping in.
