Where does the additional syllable come from?
My basic, logical brain tells me that the word "comrade" should naturally be extended to "comraderie" or "comradery" — not "comARaderie" or "comERaderie". Where does this "AR" or "ER" come from? I know that "ER" is a lovable movie space creature — or was that E.T.? — and also the title of a television series; but why is it a syllable in a word that doesn't merit or require another syllable?
