Shocking report of Pole in kill (4)
I believe the answer is:
bang
'shocking report' is the definition.
'bang' can be an answer for 'report' (I've seen this in another clue). I'm not sure about the 'shocking' bit.
'pole in kill' is the wordplay.
'pole' becomes 'n' (abbreviation for North, as in North Pole).
'in' means one lot of letters goes inside another.
'kill' becomes 'bag' (I can't justify this - if you can you should believe this answer much more).
'n' placed within 'bag' is 'BANG'.
'of' is the link.
Can you help me to learn more?
(Other definitions for bang that I've seen before include "hit" , "drug injection" , "Sudden loud noise (often 'big')" , "Report - something the hairdresser did?" , "Explosive noise" .)
