Remains of arms and legs, perhaps, but no head (6)
I believe the answer is:
embers
'remains of arms' is the definition.
'embers' can be an answer for 'remains' (remains of a fire). I'm not certain of the 'of arms' bit.
'legs perhaps but no head' is the wordplay.
'legs perhaps' becomes 'members' (leg is a kind of member).
'but no head' means to remove the first letter (the first letter could be called the head).
'members' with its first letter taken off is 'EMBERS'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for embers that I've seen before include "Remains of coal fire" , "Hot fragments of wood or coal" , "Small pieces of glowing wood or coal" , "Dying residue of a fire" , "Pieces in a dying fire" .)
