Point to map - not about town (11)
I believe the answer is:
northampton
'town' is the definition.
(city in Northamptonshire)
'point to map not about' is the wordplay.
'point' becomes 'north' (north is a kind of point).
'to' is a charade indicator (letters next to each other).
'about' is an anagram indicator.
'map'+'not'='mapnot'
'mapnot' anagrammed gives 'ampton'.
'north'+'ampton'='NORTHAMPTON'
(Other definitions for northampton that I've seen before include "County town on the Nene" , "Town in central England on the River Nene" , "Town in central England, famous for footwear" , "City? Not yet" .)
