Form and rules
How it works
1
State verbs often describe knowledge, feelings, possession, senses and relationships: know, believe, like, own, need.
2
State meanings normally use simple forms, even when they are true now: I understand, not I am understanding.
3
Action meanings can use continuous forms: She is cooking; they are working.
4
Some verbs change type with meaning: I think it's good (opinion) but I'm thinking about moving (considering).
5
Have is normally stative for possession but dynamic in activities such as have lunch or have a shower; see can mean understand, meet or use your eyes depending on context.
