3 State verbs

The present continuous is not normally used with state verbs because the meaning of the verb itself is a general truth rather than something temporary. These verbs describe thoughts, feelings, senses, possession and description.

Here are some examples of state verbs.

• thoughts: agree, assume, believe, disagree, forget, hope, know, regret, remember, suppose, think, understand

I assume you're too busy to play computer games.

• feelings: adore, despise, dislike, enjoy, feel, hate, like, love, mind, prefer, want Do you mind fi I ask you a few questions?

I love music.

• senses: feel, hear, see, smell, taste This pudding smells delicious.

• To talk about something happening now we use can: I can smell something burning.

possession: have, own, belong My parents own a restaurant.

• description: appear, contain, look, look like, mean, resemble, seem, smell, sound, taste, weigh You look like your mother. (= a permanent situation, not a temporary one)

A Some state verbs can be used in the continuous form when the meaning is temporary. Compare:

What are you thinking about? (now)

I think you should tell her exactly what happened. (my opinion, so not temporary)

I'm tasting the sauce to see if it needs any more salt. The sauce tastes delicious.

She's having a great time. (is having = is experiencing, not possession) Students don't generally have much money. (have = possession)
