Shoot commercials over by entrance to major conference venue (7)
I believe the answer is:
potsdam
'conference venue' is the definition.
The definition suggests a singular noun which matches the answer.
'shoot commercials over by entrance to major' is the wordplay.
'shoot' becomes 'pot' (I've seen this in other clues**).
'commercials' becomes 'ads' (I've seen this before).
'over' is a reversal indicator.
'by' is a charade indicator (letters next to each other).
'entrance to' suggests taking the first letters.
The initial letter of 'major' is 'm'.
'ads' back-to-front is 'sda'.
'pot'+'sda'+'m'='POTSDAM'
Can you help me to learn more?
(Other definitions for potsdam that I've seen before include "where conference was held" , "1945 conference location" , "Brandenburg capital" , "Site of nineteen forty fve conference" , "conference centre" .)
