State verbs are verbs like know, believe, understand, realise, own, want, love, hate, etc. which describe mental states and processes. They aren't usually used in continuous tenses. However, there are state verbs like have, look, think, smell, taste, see which appear in the continuous form but with a different meaning:

e.g.: You look great.(look is a state verb)

I'm looking at you.(look is an activity verb)

Activity verbs, which denote actions and processes, can be used in any tense.

!!! Verbs like have, think, feel can be both state and activity verbs. Also enjoy is a tricky verb because it refers to feelings but technically/grammatically it is an activity verb.
