Improve Your Spelling

I before E except after C? Making plurals with -s or -es (or -ies)? In English, spelling can be tricky and inconsistent. And you cant always rely on pronunciation for clues—English is full of words that sound alike but dont share the same spelling, like "there" and "their." A standard spell check can tell you if your word is spelled wrong, but not when youre using a correctly spelled word in the wrong context. Understanding the spelling conventions of English will help you improve your writing. Weve got plenty of tips to help you whip your spelling into shape.
