Reportedly given penalty for discovery (5)
I believe the answer is:
fined
'reportedly given' is the definition.
The definition and answer can be both to do with ownership as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'penalty for discovery' is the wordplay.
'penalty' becomes 'fine' (a financial penalty).
'for' says to put letters next to each other.
'discovery' becomes 'd' (this could be a standard abbreviation which I don't know about).
'fine'+'d'='FINED'
Can you help me to learn more?
(Other definitions for fined that I've seen before include "Ordered to pay penalty" , "Imposed financial penalty on" , "Fed in (anag.)" , "Mulcted" .)
