Greek union making noises when coming out (6)
I believe the answer is:
enosis
'greek union' is the definition.
(I've seen this before)
'noises when coming out' is the wordplay.
'noises' anagrams to 'ENOSIS'.
However, I am not sure how this is indicated.
'making' acts as a link.
Can you help me to learn more?
(Other definitions for enosis that I've seen before include "National union" , "Greek/Cypriot union" , "Greek union" , "international union" , "Sort of union" .)
