A woman's reminders of past warmth (5)
I believe the answer is:
ashes
'reminders of past warmth' is the definition.
Although both the answer and definition are plural nouns, I don't see how they can define each other.
'a woman's' is the wordplay.
'woman's' becomes 'shes'.
'a'+'shes'='ASHES'
Can you help me to learn more?
(Other definitions for ashes that I've seen before include "Remains from a cremation" , "Cricket honour in the fire" , "sports contest" , "Burnt residue" , "Remains of anything burnt" .)
