Cleaner fuel that draws well? (8)
I believe the answer is:
charcoal
'draws well?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'cleaner fuel' is the wordplay.
'cleaner' becomes 'char' (charwoman is a type of cleaner).
'fuel' becomes 'coal' (coal is a kind of fuel).
'char'+'coal'='CHARCOAL'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for charcoal that I've seen before include "Fuel for barbecue cookers" , "Stick of black carbon material used for drawing" , "Fuel - stick for drawing" , "Black carbon produced by burning wood" , "Art material and fuel" .)
