If coming back to stay, you may get warm here (8)
I believe the answer is:
fireside
'may get warm here' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'if coming back to stay' is the wordplay.
'coming back' says the letters should be written in reverse.
'to stay' becomes 'reside' (I've seen this before).
'if' in reverse letter order is 'fi'.
'fi'+'reside'='FIRESIDE'
'you' acts as a link.
Can you help me to learn more?
(Other definitions for fireside that I've seen before include "Comfy place for chair" , "One warmed by this" , "warm, cosy place" , "somewhere cosy" , "Inglenook" .)
