Subzero motoring necessity, as opposed to a decorative strip say (10)
I believe the answer is:
antifreeze
'subzero motoring necessity' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'opposed to a decorative strip say' is the wordplay.
'opposed to' becomes 'anti' (anti means opposing something).
'a decorative strip say' becomes 'freeze' (I can't explain this - if you can you should give a lot more credence to this answer).
'anti'+'freeze'='ANTIFREEZE'
'as' is the link.
Can you help me to learn more?
(Other definitions for antifreeze that I've seen before include "Glycol for car radiators" , "Liquid added to car radiator" , "It keeps thing flowing" , "Winter radiator additive" , "Car radiator additive" .)
