Be impartial and note this crooked receiver (3,2,3,5)
I believe the answer is:
sit on the fence
'be impartial' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'note this crooked receiver' is the wordplay.
'crooked' indicates anagramming the letters (a crooked or disrupted version of the letters).
'receiver' becomes 'fence' (I've seen this before).
'note'+'this'='notethis'
'notethis' with letters rearranged gives 'sitonthe'.
'sitonthe'+'fence'='SIT ON THE FENCE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for sit on the fence that I've seen before include "Remain undecided" , "Don't commit oneself" , "Decline to commit oneself" , "Prevaricate" , "pin down criminal" .)
