Bit of fluff was director in the aforementioned municipality? (11)
I believe the answer is:
thistledown
'director in the aforementioned municipality?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'bit of fluff' is the wordplay.
'bit of' becomes 'thistle' (I can't justify this - if you can you should give a lot more credence to this answer).
'fluff' becomes 'down' (both can mean soft feathers).
'thistle'+'down'='THISTLEDOWN'
'was' is the link.
Can you help me to learn more?
(Other definitions for thistledown that I've seen before include "A mass of feathery seeds" , "parachutes" , "Light fluff of some seeds" , "Fluff on which some seeds fly" , "What helps some seeds fly" .)
