"Do you have" vs. "Have you"

All Questions start with H.V. and contain a Verb. Now see;

Q. Do you have a pen? v.s Have you a pen?

in first “have” stands for a Verb, whilst in second, Have stands for a H.V.

Please explain it.

Do all Questions have a H.v and Verb necessarily?

Hi, most questions have a help verb but some don’t. In your example, both questions are correct but “Do you have a pen?” is more often used than “Have you a pen?” which might be a bit old fashioned.
Let me know if this answers your question and welcome to our forum.

In older forms of English, it was possible to form a question just by moving the main verb ahead of the subject. You can still hear such questions in court in the United States:

Question formation has changed since that time, and in modern-day English we use a form of the helping verb “do” before the subject in order to form the question. The only exception is when the main verb is “be”, because “is”, “am”, etc., move up ahead of the subject and do not need a helping verb to form a question.

The verb “have” used to function the same way “be” does now, and it’s still possible to move the main verb “have” to the front to make a question, but it sounds very formal, very old fashioned, and in some situations very comical.
