City information provided by president's wife? (6)
I believe the answer is:
geneva
'city' is the definition.
(Geneva is an example)
'information provided by president's wife?' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'provided by' says to put letters next to each other.
'president's wife?' becomes 'Eva' (Eva Peron, wife of Juan Peron of Argentina).
'gen'+'eva'='GENEVA'
(Other definitions for geneva that I've seen before include "City and lake in SW Switzerland" , "city of biblical significance" , "Swiss city and canton" , "International agreement on the treatment of civilians and captured or wounded military personnel in wartime" , "Swiss city - Dutch spirit" .)
