I think I can use the verb "to accept" for invitation when someone agrees to accept somebody's invitation; but I'm not sure about admit.
I don't know about refuse and reject too. I know I can use the verb refuse for an invitation but I am not sure about rejection and rehecting someone's invitation.
I want to know which one of these 4 verbs can be used for an invitation?
To accept - To admit - To refuse - To reject
