Literally "He to", I understand why this translates to "He stops", but the hints for "para" do not include "stop". I don't think simply adding it is a sufficient solution, but that means this poses a complicated problem. At least I only need to get it wrong once to remember it, which tends to actually be a decent way to learn.
If everyone here clicked on 'Report a problem' and ticked 'dictionary hints missing' then it would get fixed. They are usually pretty good about quickly fixing omissions and errors, the only reason I can think of that they've not fixed this issue is that not enough people have reported through the proper channel.
