It's a minor peeve, but it irks me every time I hear it: unlike in English, words in Latin are gendered. "Excidium" is neuter gender (not ungendered!) and it is jarring having it applied to a male dragon - the suffix -um applies to inanimate things. Not male dragons.

I could ignore this one for the sake of an English captain not knowing any better - but then there's "Eroica"! Named by a Prussian captain - when German also assigns gender to all words and such a mistake just could not happen. The word "eroica" is feminine-gendered and, again, is used as a name for a male dragon. Ugh.
