Sometimes, you can't get rid of a word. So the problem i run into alot is that when I'm writing I repeat alot, but when I go to the thesaures I find words that I haven't ever heard of, and I don't want to present my teacher with a paper what sounds like I copied and pasted of the internet.
What to do?
A good question. I sugest you make the paper the best you can in your own words. and if you need help you can quote refrences like dictionary.com, or wikipedia.com.
