… inducing this in fluster? (4)
I believe the answer is:
lust
'inducing' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'in fluster?' is the wordplay.
'in' says the answer is hidden in the clue.
'LUST' can be found hidden inside 'fluster'.
'this' is the link.
(Other definitions for lust that I've seen before include "Carnal desire" , "Depraved desire" , "Lecherousness" , "One of the seven deadly sins" , "Strong sexual desire" .)
