I’ve noticed so many spelling errors in documents I read that I have concluded many people pay no attention to their spellcheckers.
Here are some words that all end with the same sound, “seed,” but can be separated into three categories:
SEDE—Only one English word ends with this: supersede.
CEED—Only three English words end with this: succeed, proceed and exceed.
CEDE—All other English words ending with the “seed” sound use this: intercede, precede, accede, etc.
I still encourage you to pay attention to the markings your spelling and grammar check programs make on your documents.
English has quite a few words that are spelled two ways and mean the same thing. When you look these words up in the dictionary, the convention is to give the preferred spelling first. Here are some words you can spell two ways:
British people write judgement, while in America we omit that middle e. Similarly, they write colour, honour, centre and theatre, while Americans prefer color, honor, center and theater. Language changes in spelling, grammar, meaning and usage, but the changes are rarely so rapid that you can’t keep up.
