Content to square accounts in the neighbourhood (4)
I believe the answer is:
area
'the neighbourhood' is the definition.
(I've seen this before)
'content to square accounts in' is the wordplay.
'content to' indicates the answer is hidden within the clue.
'AREA' can be found hidden inside 'square accounts in'.
(Other definitions for area that I've seen before include "Region; extent of a surface" , "part of town" , "Extent of a 2-dimensional surface" , "Region, zone" , "Surface measurement" .)
