Communication system for partners screened by Coca-Cola (4)
I believe the answer is:
acol
'communication system for partners' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'screened by coca-cola' is the wordplay.
'screened by' says the answer is hidden in the clue.
'ACOL' is hidden in the letters of 'coca cola'.
Can you help me to learn more?
(Other definitions for acol that I've seen before include "Bidding system in bridge" , "often seen in bridge" , "Way to bid" , "Bridge convention" .)
