Spy screening king visiting a foreign country (9)
I believe the answer is:
argentina
'foreign country' is the definition.
'Argentina' can be an answer for 'country' (Argentina is an example). I'm not sure about the 'foreign' bit.
'spy screening king visiting a' is the wordplay.
'spy' becomes 'agent' (secret agent).
'screening' indicates putting letters inside (inserted letters are covered or screened by others).
'king' becomes 'R' (abbreviation of Latin rex).
'visiting' becomes 'in'.
'agent' placed around 'r' is 'argent'.
'argent'+'in'+'a'='ARGENTINA'
Can you help me to learn more?
(Other definitions for argentina that I've seen before include "South American country" , "state" , "FIFA World Cup winners in 1978 and 1986" , "Silver country" , "Home of the tango" .)
