Thank you very much for your answers!! :) They were very helpful !! ^_^
In conclusion, if we use the possesive pronouns كَ, كِ ,كم, كن, ه ,ها, we use them in a respectful manner (like yours/his Excellency) and it is not very ordinary to use them with the verbs. Isn't it?
Some questions came to my mind related to your answers
1/ As I read the conjugation of the verb like I noticed that the litterary translation of the verb for example in the form تُعجبني is you are liked by me (I like you).
2/ The form I like it يعجبني/تعجبني is the same for the third person I like him/her?
3/ And the form انت مُعجب به exactly means You are admirer of him?
