Continuous tenses can usually only be used with action verbs. Verbs can be of two kinds: action verbs and stative verbs. Stative verbs refer to mental and emotional states. Verbs indicating possession are also considered as stative verbs. Common stative verbs are: have, know, believe imagine, want, realize, feel, doubt, think, forget, mean, love, hate, fear, like, envy etc.

- I envy you. (NOT I am envying you.)
- He always forgets to say thank you. (NOT He is always forgetting to say thank you.)
- I appreciate your honesty. (NOT I am appreciating your honesty.)
Verbs of perceptions are also considered as stative verbs. Examples are: taste, hear, see, smell, feel etc.

- The fish smells awful. (NOT The fish is smelling awful.)
Copular verbs be, seem, appear etc., are also not used in the continuous form.
