I don't know what is different see,look and watch.
I just know when I want to say ''I watch TV'' or ''I'm looking for something'' so I sometimes confuse which word I should choose.
Also I sometimes confuse about preposition.
I always remenber all sentence and I talk so I don't know
You can watch something that moves (movies, sports) and look at something that doesn't move (picture, painting). If you take people, they can move or not, so you could use watch if you're taking in their activity and look at if you're taking in their appearance. However, this is just a rough idea and not an absolute rule. See can be used for the sense or ability, but again this isn't an absolute rule as you can use it for movies and TV, for instance.
