Allowed to contribute to police deductions (5)
I believe the answer is:
ceded
'allowed' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'contribute to police deductions' is the wordplay.
'contribute to' indicates the answer is hidden within the clue (I've seen 'contributing to' mean this (the answer contributes to part of the clue )).
'CEDED' can be found hidden inside 'police deductions'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for ceded that I've seen before include "Given up" , "Conceded or gave up" , "Gave up (power)" , "Granted" , "Relinquished" .)
