Finite and Nonfinite Verbs  

Finite and Nonfinite Verbs
Dynamic and Stative Verbs
This category of verbs deals with the verb words themselves; and whether they indicate an action or a state of the subject. This category is not concerned with the object in particular.
Dynamic Verbs
These verbs denote an actual action or expression or process done by the subject. They mean an action which can be seen or physically felt or the result of which is seen or physically felt by the object or an indirect object.
She buys new clothes every week.
Here the verb is buys which is an action done by the subject ‘she’, hence it is a dynamic verb.
He is swimming at the beach.
Here again we have the definite action swimming done by the subject ‘he’, making ‘swimming’ a dynamic verb in this sentence.
Stative Verbs

These verbs refer to the state of the subject or the situation of the subject. Stative Verbs tell us about the state of mind of the subject, or the relation between the subject and the object.
She prefers strawberry jam.
Here the Stative Verb is ‘prefers’ which shows the thinking of the subject ‘She’towards the object, which is ‘jam’.
The cupboard requires a new coat of paint.
Here the subject is ‘cupboard’ and the stative verb is ‘requires’ which is telling about the relation between the subject ‘cupboard’ and the object ‘paint’.
