I believe the answer is:

local

I'm a little stuck... Click here to teach me more about this clue!

'pub' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for local that I've seen before include "The familiar neighbourhood pub" , "stopping train" , "Anaesthetic that numbs one area of the body" , "hearing" , "Relating to the neighbourhood" .)

I've seen this clue in The Independent.
