Place for military restricted dry aperitif (7)
I believe the answer is:
campari
'aperitif' is the definition.
(I have seen 'Pinkish aperitif ' mean 'campari' so perhaps 'aperitif' could also mean 'campari')
'place for military restricted dry' is the wordplay.
'place' becomes 'camp' (camp is a kind of place).
'for' means one lot of letters go next to another.
'military restricted dry' becomes 'ari' (I can't explain this - if you can you should believe this answer much more).
'camp'+'ari'='CAMPARI'
Can you help me to learn more?
(Other definitions for campari that I've seen before include "Red, bitter-sweet Italian aperitif" , "Mildly bitter aperitif, often drunk with soda" , "bitter drink" , "Pinkish aperitif" .)
