Badly hurt widow who married a wealthy farmer (4)
I believe the answer is:
ruth
'widow who married a wealthy farmer' is the definition.
(reference to the biblical figure)
'badly hurt' is the wordplay.
'badly' is an anagram indicator.
'hurt' anagrammed gives 'RUTH'.
(Other definitions for ruth that I've seen before include "She is followed by Samuel" , "distress once?" , "- - Rendell, crime writer" , "she married Boaz!" , "Girl's name; grief" .)
