Neighbourhood concerned with having motoring group around (4)
I believe the answer is:
area
'neighbourhood' is the definition.
(a neighbourhood is an urban area)
'concerned with having motoring group around' is the wordplay.
'concerned with' becomes 'are' (I can't explain this - if you can you should believe this answer much more).
'having' is a charade indicator (letters next to each other).
'motoring group' becomes 'RAC' (originally the Royal Automobile Club).
'around' says to take the centre.
The middle of 'rac' is 'a'.
'are'+'a'='AREA'
Can you help me to learn more?
(Other definitions for area that I've seen before include "Extent of a 2-dimensional surface" , "part of town" , "Region, zone" , "topic" , "'Tract, region (4)'" .)
