Which affair in large part is worthless rubbish? (5)
I believe the answer is:
chaff
'rubbish?' is the definition.
(I've seen this before)
'which affair in' is the wordplay.
'in' indicates a hidden word.
'CHAFF' can be found hidden inside 'which affair'.
'large part is worthless' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for chaff that I've seen before include "Rubbish" , "twit" , "Separated grain husks" , "Refuse - banter" , "Laugh at" .)
