Stupid multilingual question:
In languages which use gendered pronouns for objects (Spanish, French, Italian, etc.) - who determines whether new words are masculine or feminine? I'd assume most normal words are based on centuries of tradition, but something like a modem or a blog wouldn't have that history. And what about invented words, like Dr. Seuss? If I declare that a huffletywub is a thing, do I get to pick the pronoun too?
