End of Christmas month? One may be glowing (5)
I believe the answer is:
ember
'end of christmas' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'month? one may be glowing' is the wordplay.
I cannot really understand how this works, but
'month?' could be 'm' (standard abbreviation) and 'm' is located in the answer.
'be' is within the answer.
The remaining letters 'er' is a valid word 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 ember that I've seen before include "what causes a warm glow" , "Piece of live coal" , "Remnant of bonfire" , "showing residual fire" , "Material in dying fire" .)
