Mr. Torsten..

Please, why this phrase is wrong:

:: He's not understanding What I'm saying.

And, why this one is right:

:: He's looking a lot better than he did a few days ago.

thanks in advance.

Hi Torsten

Thanks a lot.

I did a researh about 'Stative Verbs', because I want understand better, and I found this:

:: State verbs describe states (things that can't change easily or quickly, example: what you believe, think or own) . Stative verbs are not normally used in the continuous form (-ING)

Stative verbs can be grouped into theses categories:

Emotions : care, like, need, feel, loathe, prefer, hate, love, want
Ownership: own, have, possess
mind: believe, forget, know, mean, realise, remember, suppose, understand, doubt
senses: (often used with CAN ) hear, taste, see, touch, smell
others: contain, depend, matter
