Movies with spies tackling flipping army (6)
I believe the answer is:
cinema
'movies' is the definition.
(I've seen this in another clue)
'spies tackling flipping army' is the wordplay.
'spies' becomes 'CIA' (Central Intelligence Agency).
'tackling' is an insertion indicator (to tackle is to take possession of).
'flipping' shows that the letters should be reversed in order.
'army' becomes 'men' (I am not sure about this - if you are sure you should believe this answer much more).
'men' written backwards gives 'nem'.
'cia' placed around 'nem' is 'CINEMA'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for cinema that I've seen before include "The big screen" , "Films, collectively" , "Picture house" , "Motion pictures" , "Local form of language" .)
