A nym question that has been bugging me for a while is a term for the practice of following an acronym with the word the last letter stands for. As in: ATM machine, PIN number, etc. Someone I know suggested superflonym, but although I like it, I don't think it can be right. Anyone have any thoughts? I looked on the previously posted list of nym words and it's not covered (though I do like poecilonym: synonym has a synonym!).
