Unusual net domain chosen (9)
I believe the answer is:
nominated
'chosen' is the definition.
(nominating is a kind of choosing)
'unusual net domain' is the wordplay.
'unusual' indicates an anagram.
'net'+'domain'='netdomain'
'netdomain' anagrammed gives 'NOMINATED'.
(Other definitions for nominated that I've seen before include "mentioned specifically" , "Proposed as a candidate" , "selected" , "Put forward for election" .)
