My idea, with some example sentences "I am going to WATCH the football game tonight." "I need to find someone to WATCH my children." Not just to look at, but to pay focused attention. "LOOK at that man juggling knives!" "I am LOOKing for my glasses" Used when you are trying to find something, also as a command. Not used frequently to describe yourself seeing something. "SHOW him that painting you made." "Show me. (that thing that you have)" Used when presenting something to be seen or demanding someone let you see something. I have to set 'see' to the side, because even as a native speaker I am having difficulties expressing how this is used. In many cases it can be used interchangeably with watch, ("Did you watch the episode?" "Did you see the episode?" both being correct.) but in other instances it cannot. ("Watch my trick." "See my trick." Where watch is the only word that makes sense or "I am going to see my grandparents." "I am going to watch my grandparents." where see is more likely the word you want as watch has the connotation that they are infirm or require your supervision.) You are probably safe to use see only for things that you happen to view, but understand that native speakers do not always use it that way.

to:Ms.Aleksandra. I see! Thank you

When you WATCH something you observe it more closely, usually sth moving. You LOOK at something for a reason, with an intention. You SEE sth tht comes to your sight that you weren't looking for intentionally. You SHOW sth to some people - you present sth to others
