"Short, long, who knows?"
Translation:Curto, longo, quem sabe?
Is there are reason why using the feminine versions of these words is wrong?
When we are generalizing things on Portuguese, we use the masculine words.
There is no noun. We're generalizing. Most Romance languages default to masculine. It's a remnant of Roman sexism.
Hebrew also defaults to masculine. And historically, English has too, although singular they has been fairly universally adopted in colloquial speech.
I chose both the "curto, comprido, quem sabe" and the "Curto, longo, quem sabe" and I got the answer wrong when asked to choose all options that are correct
