Soldier on CIA manoeuvre sees suspicious person (9)
I believe the answer is:
paranoiac
'suspicious person' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'soldier on cia manoeuvre' is the wordplay.
'soldier' becomes 'para' (paratrooper).
'manoeuvre' indicates an anagram.
'on'+'cia'='oncia'
'oncia' is an anagram of 'noiac'.
'para'+'noiac'='PARANOIAC'
'sees' acts as a link.
Can you help me to learn more?
(Other definitions for paranoiac that I've seen before include "Person suffering from delusions of persecution" , "Sufferer from desusions of grandeur or persecution" , "Delusional" , "behaving irrationally" .)
