Sorry, my across answers are (s?l?c?e?) Position, rank gives me Status, Say 'th' for 's' gives me Lisp, Swiss-style house gives me Chalet, Ruler of a wide domain gives me Emperor.
Factor fiction - I hadn't actually done it but have the paper in front of me and have put in the across clues which gives s?l?c?e?, so can only assume that what it is although the tense is wrong
Thanks to all who replied. I think I had a senior moment when I did this crossword I have looked at it again and it does actually say chose. Sorry to have wasted peoples time.
