Large coal order for the pub (5)
I believe the answer is:
local
'pub' is the definition.
(one's local pub)
'large coal order for' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'order for' indicates anagramming the letters.
'coal' is an anagram of 'ocal'.
'l'+'ocal'='LOCAL'
'the' is the link.
(Other definitions for local that I've seen before include "Pub - not far away" , "Restricted number" , "where the neighbours drink?" , "Regional; nearby" , "One won't knock you out" .)
