My consumption of gin, perhaps, is parsimonious (5)
I believe the answer is:
mingy
'parsimonious' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I don't see?
'my consumption of gin perhaps' is the wordplay.
I cannot really understand how this works, but
an anagram of 'gin' is 'ing' which is present in the answer.
'my' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'is' acts as a link.
Can you help me to learn more?
(Another definition for mingy that I've seen is " Tight-fisted".)
