Hardest words to spell: sixteen classics

These are the sixteen words on the hardest words to spell page, in the order it lists them. Each has one trap that catches careful writers: the double M in accommodate, the second I that drops out of liaison, the -sede ending that supersede shares with no other common word.

The page explains where each word goes wrong. This is where you find out which ones you can spell: every word is read aloud, and the ones you miss come back until you spell them right a few times running. The words keep the page's order rather than being sorted by difficulty.
