Urban conditions perhaps not experienced in small place (6)
I believe the answer is:
sprawl
'urban conditions perhaps not' is the definition.
I can't tell whether this defines the answer.
'experienced in small place' is the wordplay.
'experienced' becomes 'raw' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'small' becomes 's' (abbreviation - e.g. clothes size).
'place' becomes 'pl' (abbreviation used in postal addresses).
's'+'pl'='spl'
'raw' inserted within 'spl' is 'SPRAWL'.
Can you help me to learn more?
(Other definitions for sprawl that I've seen before include "Urban or industrial expansion" , "Lie inelegantly" , "Lie in an ungainly fashion" , "Spread out untidily" , "Lie untidily" .)
