Change of street: the French relocate (8)
I believe the answer is:
resettle
'relocate' is the definition.
(resettling is a kind of relocating)
'change of street the french' is the wordplay.
'change of' indicates anagramming the letters (the letter order is changed).
'the french' becomes 'le' ('the' in French).
'street' anagrammed gives 'resett'.
'resett'+'le'='RESETTLE'
(Other definitions for resettle that I've seen before include "Move to new state" , "put down new roots" , "Take up residence in a different place" , "Move home" , "Take up living in a different place" .)
