Alcohol from Athlone? (7)
I believe the answer is:
ethanol
'alcohol' is the definition.
(I know that alcohol can be written as ethanol)
'from athlone?' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'athlone' is an anagram of 'ETHANOL'.
(Other definitions for ethanol that I've seen before include "porter uses it" , "Alcohol in wine, beer" , "intoxicating stuff" , "Ethyl alcohol" , "Kind of alcohol found in Athlone" .)
