Country suspended army, leaving Monday (7)
I believe the answer is:
hungary
'country' is the definition.
(I know that Hungary is a country)
'suspended army leaving monday' is the wordplay.
'suspended' becomes 'hung' (I've seen this before).
'leaving' indicates named letters should be taken away.
'monday' becomes 'm'.
'army' with 'm' taken away is 'ary'.
'hung'+'ary'='HUNGARY'
(Other definitions for hungary that I've seen before include "One member of NATO" , "country in Europe" , "Country bordered by Slovakia, Ukraine, Romania, Serbia, Croatia, Slovenia and Austria" , "vizsla from here?" , "It's capital is Budapest" .)
