From boronia in "if the shoe fits": "...but that could be a whole nother thread"

I don't recall ever seeing an adjective placed inside the word it modifies. Fun! Actually, I say "a whole nother" from time to time, but have never seen it written. Should there be an apostraphe in front of the n? How about after the a?! Actually, I guess there is no use in discussing the spelling of "a whole nother" since the "whole" part is redundant.

Good to see you posting again, Robert!

I just happened to be on the board when you put this up. I had a similar question once which resulted in this:

"a whole nother thread!???"

It led to a pretty intriguing discussion. If you, or anyone else, have anything to tack on, please add to it here!
