Here is a list of words that you might have misspelled and never knew because most spell checkers never catch them. I meant to put this up a long while ago and forgot. A question Parogar set forth reminded me to make it so he gets a dedication.

It's basically a list of homophones(words that sound alike), easy misspelling errors that word all too frequently never catches, and a list of words whose meanings people get confused with similar words. I acquired the better part of this list from the grammar site who I linked on the side. I added another 50 some words of my own and now I leave it here for your advantage.

I debated adding definitions but decided it would make the list too long and bloated, so you'll have to look up the different meanings on your own and decide which works best for the situation. As always, this list can be made almost infinitely long, feel free to add your own common mistakes in the comments! Thanks and Enjoy!
