Question

what is different between see watch and look

Answer 1

The differences in the definitions tell us something about how each word is used. See and hear are usually used when you are talking about using the senses of sight and sound. On the other hand, look, watch, and listen are usually used when you are talking about paying attention to what you see or hear.

However, when we use the verb 'look', we're talking about seeing something with an intention. ... When we use verbs of the senses, and this group, 'look', 'see' and 'watch' are verbs of visual sense, there's usually a difference between intention and non-intention, so, for example, "I heard the radio."

See: It means to perceive with the eyes.

Look: It means to direct one's gaze in a specified direction.

View: (with object) It means to look at or inspect.

Watch: (with object) It means to look at or observe attentively over a period of time
