In English, "see" and "look" have very similar meanings, while "oversee" and "overlook" have almost opposite meanings. I find this amusing. It's even more amusing when it shows up on a resume like the one I saw today:
I overlooked a team of five doing blah, blah, blah...
So, did this person fail to notice a team of five that was doing a lot of important work? Or did he actually mean that he "oversaw" them?
I also notice that we can have an insight, but not an outsight. We can have an outlook, but not an inlook. We can oversee and overlook, but we can't undersee or underlook, unless we are perhaps undersea.
