Flimsy fastening implicated in destruction (8)
I believe the answer is:
banknote
'flimsy' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'fastening implicated in destruction' is the wordplay.
'fastening' becomes 'knot' (knot is a kind of fastening).
'implicated in' is an insertion indicator.
'destruction' becomes 'bane' (I've seen this in another clue).
'knot' put into 'bane' is 'BANKNOTE'.
Can you help me to learn more?
(Other definitions for banknote that I've seen before include "Money" , "Monetary quantity" , "Paper cash" .)
