Charge captor and janitor (9)
I believe the answer is:
caretaker
'janitor' is the definition.
(I've seen this before)
'charge captor' is the wordplay.
'charge' becomes 'care' (synonyms).
'captor' becomes 'taker' (I've seen this in another clue).
'care'+'taker'='CARETAKER'
'and' acts as a link.
(Other definitions for caretaker that I've seen before include "One looking after a building" , "Warden" , "Janitor" , "Custodian, keeper" , "School worker, perhaps" .)
