Punished, some fine day (5)
I believe the answer is:
fined
'punished' is the definition.
(similar in meaning)
'some fine day' is the wordplay.
'some fine' becomes 'fine'.
'day' becomes 'd' (abbreviation for day).
'fine'+'d'='FINED'
(Other definitions for fined that I've seen before include "Fed in (anag.)" , "Mulcted" , "Ordered to pay penalty" , "Imposed financial penalty on" .)
