Common mistake
Saying 'see TV' instead of 'watch TV'. Wrong: "I like to see TV after dinner." (correct: watch TV)
Trick to remember it
'See' = passive, something enters your visual field. 'Watch' = active, you choose to pay attention. TV, sports, movies at home: always 'watch'. Lightning, accidents, something unexpected: 'see'.
Quick rule
Did you perceive it spontaneously, without choosing to? Use 'see'. Are you giving it active, sustained attention? Use 'watch'.
Did you know?
For movies at the cinema, both 'see' and 'watch' are widely used: 'Did you see the new Marvel movie?' and 'Did you watch it?' are both natural. The distinction is stricter with TV: you always 'watch TV', never 'see TV'.
