In need of a drink? This malt whisky, in conclusion, is about right (7)
I believe the answer is:
thirsty
'in need of a drink?' is the definition.
(I've seen this in another clue)
'this malt whisky in conclusion is about right' is the wordplay.
I cannot really understand how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
an anagram of 'this' is 'hist' which is present in the left over letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for thirsty that I've seen before include "Keen" , "Needing a drink" , "Needing moisture" , "Parched" , "Wanting a drink" .)
