Grammar explanation

Stative verbs describe a state rather than an action. They aren't usually used in the present
continuous form.

I don't know the answer. [DEL: I'm not knowing the answer. :DEL]
She really likes you. [DEL: She's really liking you. :DEL]
He seems happy at the moment. [DEL: He's seeming happy at the moment. :DEL]

Stative verbs often relate to:
  * thoughts and
opinions: agree, believe, doubt, guess, imagine, know, mean, recognise, remember, suspect, think, u
nderstand
  * feelings and emotions: dislike, hate, like, love, prefer, want, wish
  * senses and perceptions: appear, be, feel, hear, look, see, seem, smell, taste
  * possession and measurement: belong, have, measure, own, possess, weigh.

Verbs that are sometimes stative

A number of verbs can refer to states or actions, depending on the context.

think

I think it's a good idea.
Wait a moment! I'm thinking.

The first sentence expresses an opinion. It is a mental state, so we use present simple. In the
second example the speaker is actively processing thoughts about something. It is an action in
progress, so we use present continuous.

Some other examples are:

have

I have an old car. (state – possession)
I'm having a quick break. (action – having a break is an activity)

see

Do you see any problems with that? (state – opinion)
We're seeing Tadanari tomorrow afternoon. (action – we're meeting him)

be

He's so interesting! (state – his permanent quality)
He's being very unhelpful. (action – he is temporarily behaving this way)

taste

This coffee tastes delicious. (state – our perception of the coffee)
Look! The chef is tasting the soup. (action – tasting the soup is an activity)
