The short answer is ... its doesn't tell you - and I don't know. I've now ripped up the grid in disgust that for about the third time in four there's been a contentious clue. I don't think the crossword editor is doing a great job on the Jumbo2 recently.
I think you were involved in a previous thread about blowing/blewing and multiple clues for idiot - I got three answers wrong on that one!
