Possible home of a French girl in part of East London (8)
I believe the answer is:
bungalow
'possible home' is the definition.
(type of residence)
'a french girl in part of east london' is the wordplay.
'a french' becomes 'un' ('a' in French).
'girl' becomes 'gal'.
'in' means one lot of letters goes inside another.
'part of east london' becomes 'Bow' (area of London).
'un'+'gal'='ungal'
'ungal' inserted into 'bow' is 'BUNGALOW'.
'of' is the link.
(Other definitions for bungalow that I've seen before include "Single-storey home" , "Single storey house" , "One-storied house" , "Low building" , "One-storeyed house" .)
