Talk:top dead center

Is it a noun?

I am waffling between noun and adjective for this article. I'm not much of a dictionarian. It occurs to me that since top dead center describes a place in the combustion process that it is a noun. However, the fact that it describes that place makes me think it is an adjective. But then I think, I'm not saying "that stroke is very top-dead-centery", I am saying "the stroke has arrived at top dead center." So I think it is probably a noun. Avriette 16:57, 12 Mar 2005 (UTC)

I'd have to say Noun. Person, place or thing. Top dead center is a place on a flywheel, used as a reference point. --Connel MacKenzie 17:07, 12 Mar 2005 (UTC)

Well, in the phrase "top dead centre position" t.d.c. would be an adjectival phrase, but I have never seen that usage - it is always "top dead centre" used as a noun. SemperBlotto 17:15, 12 Mar 2005 (UTC)
