Officer on weekend consumed by Bowie in bar (8)
I believe the answer is:
blockade
'bar' is the definition.
('blockade' can be a synonym of 'bar')
'officer on weekend consumed by bowie' is the wordplay.
'officer' becomes 'oc' (I've seen this in other clues).
'on' says to put letters next to each other.
'weekend' becomes 'k' (I've seen this in other clues).
'consumed by' means one lot of letters goes inside another.
'bowie' becomes 'blade' (I am not sure about this - if you are sure you should believe this answer much more).
'oc'+'k'='ock'
'ock' going within 'blade' is 'BLOCKADE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for blockade that I've seen before include "Military restriction of access" , "Seal off (a place)" , "Prevent(ion of) access and exit" , "Barricade" , "Isolation of place by sea" .)
