When did he get there?
He arrived at the top [of the mountain] at the end of the day.
What does this mean? In english, it seems this would only be a partial sentence, as you'd need a noun for further context..."He arrived at the top of the stairs just as she was about to leave"
He may have just finished climbing a mountain/wall. Or less common you might see it referring to comparative order, such as in sports. For example: "Tiger Woods began the 18th hole at the bottom of the group. He arrived at the top"
'He arrived on top' is acceptable at my house. Not sure if the original Portuguese can distinguish between 'on top' and 'at the top'.
Ao topo = at the top (the article "the" usually requires more specificity)
ao topo desta escada / ao topo do pódio/ ao topo da montanha/ ao topo da minha carreira
I put "He made it to the top," which at least Reverso seems to indicate is ok (it's actually the first alternative listed). It was counted wrong and "He gets to the top" offered as the correct alternative. Any explanation for that? The tense doesn't match.
