<< And as I understood it, "promenade" is a shortening of "Spring Promenade", which I still believe is a reference to a specific dance. After all, there is usually more than one formal dance each year for a HS, therefore I still think that one can refer to Prom without an article. For example, "Pittsburgh" is really just a shortening of "City of Pittsburgh". One would say "I'm going to the City of Pittsburgh.", but one would not say "I'm going to the Pittsburgh." I have no idea if I'm right or not, but my reasoning makes sense to me at least. >>
I've never seen promenade as a shortened for of Spring Promenade.. and that's merely and adjective, spring, describing the event, the promenade... and then used as a proper noun. Promenade itself is a simple noun meaning a formal dance or ball, or as a verb.. well you can look it up. Pittsburgh isn't a shortened form of "City of Pittsburgh," the latter is just more descriptive. That's like saying my real name is Mr. TheVrolok, TheVrolok is just a shortened form.
