Exchanged intelligence with Charlie in storage facility (8)
I believe the answer is:
switched
'exchanged' is the definition.
(switching is a kind of exchanging)
'intelligence with charlie in storage facility' is the wordplay.
'intelligence' becomes 'wit' (wit is a kind of intelligence**).
'with' says to put letters next to each other.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' is an insertion indicator.
'storage facility' becomes 'shed' (I've seen this before).
'wit'+'c'='witc'
'witc' going into 'shed' is 'SWITCHED'.
(Other definitions for switched that I've seen before include "Exchanged" , "could well be beaten" , "Swapped over" , "Changed course" , "Turned electric appliance on or off" .)
