They are also called state verbs. These are verbs that describe states rather than actions. They are often verbs which refer to thoughts, feeling and senses (e.g., love, understand, believe, see). These verbs are not usually used in continuous forms as they refer to something which is seen as permanent. When they are used in continuous form, the meaning is often slightly different (compare: I see the flowers with I'm seeing her tonight).

Most verbs are dynamic verbs; they describe physical actions and can be used in continuous forms.
