One feeling the heat for one feeling the cold (7)
I believe the answer is:
sweater
'one feeling' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'the heat for one feeling the cold' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'for one' could be 'ea' ('ea' is an abbreviation for each ie 'for one') and 'ea' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sweater that I've seen before include "A present from Mum!" , "Guernsey" , "Woolly" , "Re waste: it's a garment" , "slave-driver" .)
