All verbs in English are classified as either stative or action verbs (also referred to as 'dynamic verbs'). Action verbs describe actions we take (things we do) or things that happen. Stative verbs refer to the way things 'are' - their appearance, state of being, smell, etc. The most important difference between stative and action verbs is that action verbs can be used in continuous tenses and stative verbs can not be used in continuous tenses.

Common Stative Verbs
There are many more action verbs than stative verbs. Here is a list of some the most common stative verbs:
Be , hate, like, love, need, belong, believe, cost, get, impress, know reach, recognize, taste, think, understand
You may notice that some of these verbs can be used as action verbs with different meanings. For example, the verb 'to think' can either express an opinion, or the process of considering. In the first case, when 'think' expresses an opinion it is stative:
I think she should work harder on her math.

'Think', however, can also express the process of considering something. In this case 'think' is an action verb:
They're thinking about buying a new house.
She's thinking of joining a health club.
Generally, stative verbs fall into four groups:
Verbs Showing Thought or Opinions know believe understand recognize
