Mention a new name (8)
I believe the answer is:
nominate
'name' is the definition.
'mention a new' is the wordplay.
'new' indicates an anagram.
'mention'+'a'='mentiona'
'mentiona' is an anagram of 'NOMINATE'.
(Other definitions for nominate that I've seen before include "Propose for office" , "Designate" , "Specify (person for job)" , "Propose - a mention (anag)" , "Put forward (as candidate for election)" .)
