Put aside like supine flamer (2,3,4,6)
I believe the answer is:
on the back burner
'aside like supine flamer' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'put' is the wordplay.
I cannot really understand how this works, but
'put' could be 'the' (I've seen this in other clues) and 'the' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for on the back burner that I've seen is " Set aside".)
