I would say early or late, probably because it rolls off the tongue easier that way. Why is the Spanish expression expressed this way?
Why not, "Is he late or early?" If it were a girl should it be, "Es tarde o temprana?"
one of the possible answer given by Duo is "Sooner or later" What does not Work? and another question. Why not : Is it late or early?
kinda funny, because in English everyone says it the other way, "Is it early or late?" but, viva la diferencia!
