Arrest English diplomat (7)
I believe the answer is:
attache
This could be a double definition.
'arrest english' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'diplomat' is the second definition.
(I know that attache is a type of diplomat)
Can you help me to learn more?
(Other definitions for attache that I've seen before include "Junior ambassador" , "Specialised envoy" , "ambassador's assistant" , "Ambassador's aide" , "That ace (anag.)" .)
