Pathan carelessly consumes Henry’s fuel (7)
I believe the answer is:
naphtha
'fuel' is the definition.
The definition and answer can be both substances as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'pathan carelessly consumes henry's' is the wordplay.
'carelessly' indicates an anagram.
'consumes' means one lot of letters goes inside another.
'henry' becomes 'h' (symbol for the unit of electrical inductance).
'pathan' with letters rearranged gives 'naphta'.
'naphta' going around 'h' is 'NAPHTHA'.
Can you help me to learn more?
(Other definitions for naphtha that I've seen before include "Solvent ingredient" , "Inflammable distilled liquid" , "Inflammable oil" , "Bad-smelling distillate of carbon" , "Oil obtained from coal; hath pan (anag.)" .)
