Stative Verbs

Stative verbs describe states rather than actions — they are not normally used in continuous tenses. Some verbs can be both stative and dynamic depending on meaning.

Shown in purple — can also be used as an action verb with a different meaning e.g. I think it's true (stative) vs. I'm thinking about it (action)

amaze agree belong feel appear
appreciate believe have hear be
astonish desire own look consist
care doubt possess see contain
envy feel smell cost

like/dislike guess taste include

please realise resemble

20 Most Common Stative Verb Errors

These are the mistakes learners make most frequently when using — or misusing — stative verbs in English.

1 Continuous with think (opinion)
I am thinking that you are right.
I think that you are right.
When think expresses an opinion or belief, it is stative and cannot take the -ing form.
2 Continuous with know
I am knowing the answer.
I know the answer.
Know is always stative — it describes a mental state, never an activity in progress.
3 Continuous with love/like/hate
I am loving this film so much.
I love this film so much.
Emotions like love, like, hate, prefer are states, not actions. Exception: I'm loving it is an informal/marketing usage.
4 Continuous with belong
This bag is belonging to me.
This bag belongs to me.
Possession verbs (belong, own, possess) describe permanent states and never take -ing.
5 Continuous with believe
I am believing you.
I believe you.
Believe is a mental state verb. It cannot express an ongoing activity.
6 Continuous with understand
I am understanding the lesson now.
I understand the lesson now.
Understand is stative — it refers to a mental state, not a process you can watch happening.
7 Confusing see (perception) with look (action)
I am seeing the mountains from here.
I can see the mountains from here.
Involuntary perception see is stative. I'm seeing a doctor (= meeting) is the dynamic exception.
8 Continuous with smell (perception)
The soup is smelling delicious.
The soup smells delicious.
When smell describes a quality of the subject (stative link verb), no -ing. I'm smelling the soup (action = sniffing) is fine.
9 Continuous with taste (quality)
This cake is tasting wonderful.
This cake tastes wonderful.
Taste as a linking verb (expressing quality) is stative. The chef is tasting the sauce (action = testing) is dynamic.
10 Continuous with need
I am needing more time to finish.
I need more time to finish.
Need in the sense of requirement or necessity is stative. The continuous is needing sounds unnatural to native speakers.
11 Continuous with want
I am wanting a coffee, please.
I want a coffee, please.
Want describes a desire — a mental state. It is not an activity and cannot be used in the continuous.
12 Continuous with have (possession)
I am having a car.
I have a car.
Have = possess is stative. I'm having breakfast / a shower / a great time are dynamic exceptions where have means experience or take.
13 Continuous with remember
I am remembering her birthday now.
I remember her birthday.
When remember means to have something in memory (state), it is stative. I'm trying to remember (making an effort) can be dynamic.
14 Continuous with seem/appear
She is seeming very tired today.
She seems very tired today.
Seem and appear are always stative linking verbs. They describe how something strikes an observer, not an activity.
15 Continuous with contain/include
This dish is containing nuts.
This dish contains nuts.
Contain and include describe composition — a permanent fact. They are always stative.
16 Continuous with cost/weigh
The ticket is costing €50.
The ticket costs €50.
Cost and weigh when expressing measurement are stative. Exception: The project is costing us more than expected (dynamic — accumulating cost).
17 Continuous with mean
What are you meaning by that?
What do you mean by that?
Mean (= signify or intend) is stative. I'm meaning to call her (= intending) is occasionally used informally but remains non-standard.
18 Using simple instead of continuous for dynamic have
I have a great time at the party now.
I'm having a great time at the party.
When have is dynamic (= experience), it takes the continuous. Students often apply the stative rule incorrectly to all uses of have.
19 Continuous with agree/disagree
I am agreeing with your opinion.
I agree with your opinion.
Agree and disagree express a mental stance — a state of mind — not an activity one can observe in progress.
20 Continuous with prefer
I am preferring tea to coffee.
I prefer tea to coffee.
Prefer expresses a long-term preference — a stable state. It is never used in the continuous, regardless of the time frame.
