Raw component of wind is energy supplier (5,3)
I believe the answer is:
crude oil
'energy supplier' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'raw component of wind' is the wordplay.
'raw' becomes 'rude' (synonyms).
'component of' indicates putting letters inside.
'wind' becomes 'coil' (coiling is a kind of winding).
'rude' placed within 'coil' is 'CRUDE OIL'.
'is' is the link.
Can you help me to learn more?
(Other definitions for crude oil that I've seen before include "output from rig" , "From which petrol is made" , "Source of fuel" , "liquid asset" , "Unrefined petroleum" .)
