By inverting the finite "had" with the subject, is the equivalent of an "if"- clause obtained.
eg:-Had I (=if I had) been----If Clause
I would know-----main clause,rewritten for the time being.
Other verbs in a pattern have a noun as direct object.
Have , meaning possess/take/eat/drink/---with related objects follows:-
eg:-Have you had--(S+v)
eating yet?----(n,related obj.)
