Charge split by Spanish college, a man thought (9)
I believe the answer is:
suspected
'thought' is the definition.
(suspecting is a kind of thinking)
'charge split by spanish college a man' is the wordplay.
'charge' becomes 'sue' (as in suing somebody in court).
'split by' indicates putting letters inside (some letters split a word into two).
'spanish' becomes 'sp'.
'college' becomes 'c'.
'a man' becomes 'ted' (Ted is a man's name).
'sue' enclosing 'sp' is 'suspe'.
'suspe'+'c'+'ted'='SUSPECTED'
(Other definitions for suspected that I've seen before include "mistrusted" , "Doubted the truth of (something)" , "Believed likely or distrusted" , "Imagined to be true" , "Believed to be guilty but without proof" .)
