This page discusses the matter.From my book: "Lexical HAVE , especially in the broad sense of possession, may also be treated as on operator. Examples: I haven't any idea; Have you a book on this subject?". I think "operator" means "auxiliary", but I am not so sure! Can you help me, please?
I don't know. In my sentence I understand "lexixal have" as "main verb", "full verb". For example. Is "I haven't any idea" the same of "I don't have any idea"?No, I think it means the opposite of auxiliary; it is a 'full verb.' It means that while 'have' is often used as auxilary verb, in many case it is the main verb, especially when talking about possession.
I have answered the question. --- auxiliary usage to 'answer'
I have a question. -- operator usage (used as a full verb, not as an auxiliary)
