Old flames (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
exes
'old flames' is the definition.
(ex-partners)
This is the entire clue.
(Other definitions for exes that I've seen before include "Expenses (abbrev.)" , "Claims made" , "old dates" , "divorcees?" , "former union members" .)
