What are state verbs?

Thinking...

From wikipedia:

"A stative verb is one that describes a state of being, in contrast to a dynamic verb which describes an action. The difference can be categorised by saying that stative verbs are static or unchanging throughout their entire duration, whereas dynamic verbs describe a process that changes over time. Many languages distinguish between these two types in terms of how they can be used grammatically."
