Munich Agreement to sweep across nation (5)
I believe the answer is:
japan
'nation' is the definition.
(Japan is an example)
'munich agreement to sweep across' is the wordplay.
'munich agreement' becomes 'ja' ('yes' in German).
'to' means one lot of letters go next to another.
'sweep across' becomes 'pan' (I've seen this before. I am not sure about the 'across' bit.).
'ja'+'pan'='JAPAN'
Can you help me to learn more?
(Other definitions for japan that I've seen before include "Land of the Rising Sun" , "'Country of more than 3,000 islands (5)'" , "Glossy coating" , "Glossy black lacquer" , "It's a string of more than 3,000 islands" .)
