Burning neat alcohol powers this stove (4)
I believe the answer is:
etna
'stove' 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 don't see?
'burning neat alcohol powers' is the wordplay.
'neat' can be anagrammed to 'ETNA'.
But, I'm not sure how the anagram is indicated.
'this' acts as a link.
Can you help me to learn more?
(Other definitions for etna that I've seen before include "A feature of Sicily" , "source of fumes?" , "Natural hazard" , "Volcano; reverse of stake" , "Heating vessel" .)
