Okay, I did a search that answered most of my capitalization uncertainties, but this one remains unresolved.
Normally, one captializes nationalities, right? “I know a little German, he’s sitting over there.” or “Where’s he from? Oh, he’s English.”
Now, in, say, your average SF novel, you might have several different intelligent species, so when you refer to them, do you captialize them? It doesn’t seem to be appropriate, since you wouldn’t capitalize “human.”
“What is that ugly thing?”
“Oh, that’s a human.”
And of course, I consulted Foreigner to see what Cherryh did, and she doesn’t capitalize “atevi” or “human,” and that makes sense to me. But I’ve seen it done:
“Who’d have thought Klingons would be such noisy neighbors. I wish our room was next to the Vulcans. Hey, could you pour me another Romulan ale?”
So lets say, hypothetically of course, that I’m working on a draft of a science fiction novel. Should I captialize my non-human species names, or not?
