Try typing the word into google. Just google. google will ask if you mean the correct/proper/right word. (usually and depending on the tools you have set up on google).
When you see the word you think is the word you want, click on it and you'll see all kinds of references to it. If all those are wrong, Oh Well.
That's my DB spell check. At least for here where spell check doesn't work and I just can't spend too much time checking.
