As a matter of fact, verbs are in two classes "Dynamic" and "Stative"Originally Posted by Elsa
The progressive (continuous) occurs only with dynamic verbs,such as: ask, call, play, say, read, etc.
As for stative
1- verbs of inert perception and cognition e.g. hear, like, love, know, see
smell, taste, want, wish, etc
2- Relational verbs e.g. apply to, belong to, contain, need, involve, deserve, include, etc.
Thus, (I am hearing, I am seeing) are not right. as well as (I am tasting).
As for "I am having a dinner". Here you can say I am having a dinner as "having " here means "eating" not "possess" therefor you can not say (I am having money***) for Have here means possession.
