Take exception to the whole idea (6)
I believe the answer is:
object
This clue could be a double definition.
'take exception to' is the first definition.
(thesaurus)
'the whole idea' is the second definition.
'object' can be an answer for 'idea' (thesaurus). I am unsure of the 'the whole' bit.
Can you help me to learn more?
(Other definitions for object that I've seen before include "Don't agree" , "Express disapproval" , "Argue against - purpose" , "design?" , "Item - demur" .)
