Nearest thing to a boozer (5)

I believe the answer is:
local
'boozer' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for local that I've seen before include "Restricted number" , "Pub around the corner?" , "Regional, parochial" , "Nearby pub" , "Purchase" .)
