I think it’s to make it less ambiguous.

In English you just use the same word and figure it out from context. Someone else gave some other Spanish examples but I like “right” (direction) = “la derecha” vs “right” (human rights) = “los derechos”.

Of course there’s still so many variants of meaning that grammatical gender doesn’t help much.

Now if you would level up once more and stopped having gendered pronouns.

That’s the ultimate level 😀
