Hi all, I wonder if anyone can help me with this, please?
What are the rules for deciding the gender of brand-named products?
I seem to encounter this a lot in cafes when ordering drinks. Are Coca Cola and Sumol both feminine because they are “bebidas”? Or is the gender determined by general spelling rules, e.g. uma Coca Cola but um Sumol?
Similarly with cars. Are they all masculine from “carro”, or is it um Nissan but uma Kia?
Hope this makes sense!
Thank you
