Grammar errors are grouped into phrase usage, grammar mechanics, and punctuation.

Spelling
Grammarian PRO3, the most powerful spell checking in the world, includes grammar-check-lite spell checking and additionally checks for such spelling errors as: word compounding, homophones, spelling out numbers in a sentence, capitalizing of proper nouns, and more. ONLY Grammarian PRO even makes spelling suggestions based on how words are used in the sentence.
Homophones-not misspelled but spelling is incorrect...
Have you ever used the word it's as a possessive pronoun when you meant to use its. Or maybe you wrote to complement someone instead of compliment them. Well, these words are not misspelled but the spelling is incorrect depending on the context that the words are used. Grammarian PRO3 spots correctly spelled words that used in the wrong context. No more embarrassing typos like it's-its, complement-compliment, then-than, to-two-too, lose-loose. Homophones are common spelling and grammar check errors. And common spelling checkers cannot catch these errors. Grammarian PRO3's spelling and grammar check easily catches them, and other than a trained human editor, ONLY Grammarian PRO3 catches them.
If you are a dyslexic typist, Grammarian PRO now helps you more than ever. PRO3's spelling and grammar check has the most comprehensive homophone checking ever. Nothing has ever before been successfully capable of checking and correcting these types of spelling and grammar check errors.

NBC Nightly News:
Americans' bad grammar costly. When the words are far from perfect and the boss has had enough.
Brian Williams, "We're in a bad grammar epidemic in this country. Perhaps, you've seen signs of it yourself in memos, documents, and computer-speak on the internet. Grammar and spelling have really gone the way of the black-and-white television set these days. What happened to the English language?
Why has grammar gotten increasingly WORSER?" "It seems us Americans ain't talking too good, don't write worth a lick, and worser with emails." states NBC's Roger O'Neil. "Our grammar, punctuation, and spelling are/is abysmal. And Corporate America is saying STOP! A recent survey found that Fortune 500 companies are spending more than 3 billion dollars per year retraining workers in Basic English. Even writers have trouble writing." Business Writing Instructor, Roger S. Peterson, states "We simply now must salvage American English."
