Recount sadly ending in defeat (7)
I believe the answer is:
trounce
'ending in defeat' is the definition.
'trounce' can be an answer for 'defeat' (I've seen this before). I'm not sure about the 'ending in' bit.
'recount sadly' is the wordplay.
'sadly' is an anagram indicator.
'recount' is an anagram of 'TROUNCE'.
Can you help me to learn more?
(Other definitions for trounce that I've seen before include "Slaughter" , "Beat heavily" , "Beat resoundingly" , "Roundly defeat" , "Rout" .)
