Perhaps I can help here. The potential for new words does not have anything to do with style guides.

The "n" helps the transition to a vowel. "H" is not a vowel. "Historian" is not whatever Keith describes it as either.

I for one am quite happy however to allow this to sidetrack in order to let Keith save a little credibility. Notwithstanding he doesn't do so himself, and he has in the past tried to make people like me look dirty and disease ridden.

But that's him. It isn't me, it isn't most of us on Mudcat.
