Country roads around housing estates gated to begin with (7)
I believe the answer is:
senegal
'country' is the definition.
(Senegal is an example)
'roads around housing estates gated to begin with' is the wordplay.
'roads' becomes 'lanes' (I've seen this in other clues).
'around' is a reversal indicator.
'housing' means one lot of letters goes inside another.
'to begin with' indicates taking the first letters.
The first letters of 'estates gated' is 'eg'.
'lanes' reversed gives 'senal'.
'senal' placed around 'eg' is 'SENEGAL'.
(Other definitions for senegal that I've seen before include "French-speaking west African republic" , "Land" , "W African republic" , "Part of Africa" , "Northwest African country" .)
