When should I use "look", "see", and "watch"?

I'm watching "Star Trek".
Have you seen "Star Trek"?

Are the examples above correct?

1 Answer 1


Here are some simple rules that will help deciding which word to use:

  • See is used as inactive word; you just see without any effort:

    • you have visual impression: "I can see my home over there", "I see trees of green"
    • you understand: "I see what you mean"
  • Look is used as active word, you make an effort to see:

    • you try to see: "look at this!" (maybe you have to turn your head or stand up)
    • you pay an attention: "to look for a baby"
    • you search for something: "you can look up the word in the dictionary"
  • Watch is also an active word; you also make an effort, but it is for a longer period of time:

    • "I'm watching "Star Trek", "I like to go to a zoo and watch tigers playing"
    • pay attention: Watch the kittens as they may run away.

Here's an example demonstrating the difference:

I'm looking, but I don't see it.

Back to examples:
I'm watching "Star Trek" — it is a continuous action;
Have you seen "Star Trek"? — it is a question if you ever seen it at all, or do you know about it;
It can be also formulated: Have you watched "Star Trek" all night?, and it will mean that you have spent all night watching a movie.

  • So can you watch a picture or a statue? Mar 28, 2015 at 19:22
  • To watch a picture or statue sounds strange. You look at it, you don't watch it. "Have you seen "Star Trek"? — it is a question if you [have] ever seen it at all, or do you know about it." So in this case, it's best to ask, "Have you ever watched 'Star Trek?'"
