Country life in France, over time, upsets husband? (7)
I believe the answer is:
vietnam
'country' is the definition.
(Vietnam is an example)
'life in france over time upsets husband?' is the wordplay.
'life in france' becomes 'vie' ('life' in French).
'over' means one lot of letters go next to another (in a down clue, some letters go over others).
'time' becomes 't' (abbreviation).
'upsets' is a reversal indicator.
'husband?' becomes 'man' (a married man).
'man' reversed gives 'nam'.
'vie'+'t'+'nam'='VIETNAM'
(Other definitions for vietnam that I've seen before include "Asian country, capital Hanoi" , "South-east Asia country" , "Communist state of Indochina" , "The dong its currency" , "Far Eastern country" .)
