Vi scias kion tio signifas
I put: "Liaj ŝuoj malgrandas."
Is that wrong? I thought you could do that with adjectives in Esperanto to convey, "it is [adjective]".
It's fine. I just put that myself, and it was accepted with no problems.
is: "Liaj sxuoj malgrandajs" okey, or is it "malgrandasj" or is it not allowed to make a plural-adjective a verb?
Why is there no "n" on sxuoj?
Why would it need one? I don't think it's an accusative sentence. "His shoes are small" doesn't have a direct object.
