Donated, assumed (5)
I believe the answer is:
given
This clue is a double definition.
'donated' is the first definition.
(similar in meaning)
'assumed' is the second definition.
(I've seen this in another clue)
(Other definitions for given that I've seen before include "Awarded" , "supplied" , "Provided" , "Handed over; an 18 dn" , "Specified, stated" .)
