Number close enough? (5)
I believe the answer is:
local
This clue is a double definition.
'number' is the first definition.
(local local anaesthetic is a type of 'numb-er')
'close enough?' is the second definition.
(Other definitions for local that I've seen before include "In the vicinity" , "Nieghbourhood pub or its customer" , "In nearby area" , "The familiar neighbourhood pub" , "Pub down the road?" .)
