See vs. Look vs. Watch

See is a verb of perception, it is a sense. It is automatic and doesn't require a decision to use this sense. It is associated with things that we can't avoid.

Look and Watch are action verbs that require a decision for you to use them. They never happen automatically.

Look is used to suggest a direction for your eyes. Usually we use this verb when the things we look at doesn't move.

Look - camera, prices, mirror, sky.

• Look at this picture.
• I like to look at the stars at night.

Watch is when we talk about concentrating on something, like a movie or sports. Using watch suggests there is a movement involved, so you can use that for TV or movies.

Watch - a movie, a TV program, a football match.

• I like to sit on the verandah and watch people walk by.
• I watch Friends everyday on TV.
