How someone may be loved with much suffering? (6)
I believe the answer is:
dearly
This clue is a double definition.
'how someone may be loved' is the first definition.
(dearly beloved)
'with much suffering?' is the second definition.
(as in paying dearly for something)
(Other definitions for dearly that I've seen before include "paying for big mistakes like this!" , "How I love my wife" , "At a high price - with fondness" , "Very much; at great cost" , "At high cost" .)
