CIA for example means business (6)
I believe the answer is:
agency
I believe this is a triple definition!
'cia for example' is the first definition.
(cia is a kind of agency)
'means' is the second definition.
(I've seen this before)
'business' is the third definition.
(I know that agency is a type of business)
(Other definitions for agency that I've seen before include "Travel ..., advertising..., employment" , "Business that works on behalf of another" , "Bureau finding jobs etc" , "Travel --; dating --" , "Function of one who acts for another" .)
