Perhaps, though it does not seem the sort of thing one would likely
learn in studying or teaching a language; one would need to have
studied geology in French or heard it repeated by someone who did.  It
also doesn't explain why *Hagrid* as opposed to Rowling herself would
have it in mind.  So I think my impression (that Hagrid was supposed
to have misremembered the English-language rule) is more likely.
