A question about the usage of 'Mr'

[Infin1ty]

Hello,

I have a silly question regarding the usage of 'Mr'. I was taught that Mr is an English honorific and should be before the family name or full name of a man. For instance: a man whose name is David Jones, then we can call him Mr David Jones or Mr Jones. Thus comes my question: I'd like to know if it is proper for me to call him Mr David? Will 'Mr David' be acceptable?:? Many thanks.

As you have said yourself, Mr is usually followed by a surname or a man's full name. You shouldn't use it in connection with his first name though. Mr David or Mr Frank sounds rather strange.

Yes, it would be correct to say although it's sounds very formal.
