New house after revolution in French city (5)
I believe the answer is:
nimes
'french city' is the definition.
(I've seen this before)
'new house after revolution' is the wordplay.
'new' becomes 'n'.
'house' becomes 'semi' (I've seen this before).
'after revolution' is a reversal indicator.
'semi' written backwards gives 'imes'.
'n'+'imes'='NIMES'
'in' is the link.
(Other definitions for nimes that I've seen before include "French city after which denim is named" , "S. French city, Roman remains" , "French town" , "City in southern France, giving its name to denim" , "French city with a well-preserved Roman temple and arena" .)
