Cards used to stir fire (5)
I believe the answer is:
poker
'fire' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'cards used to stir' is the wordplay.
I cannot quite see how this works, but
'stir' could be 'poke' (poking is a kind of stirring) and 'poke' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for poker that I've seen before include "A game for the fireplace implement" , "Stiff rod; card game" , "Fire prodder; game" , "Rod; betting game" , "Park/zoo attendant" .)
