Talks or possibly eats (6)
I believe the answer is:
orates
'talks' is the definition.
(orating is a kind of talking)
'or possibly eats' is the wordplay.
'possibly' indicates anagramming the letters.
'eats' anagrammed gives 'ates'.
'or'+'ates'='ORATES'
(Other definitions for orates that I've seen before include "Speaks formally, makes speech" , "Talks pompously" , "Talks grandly from a platform" , "Speechifies" , "Makes lengthy or pompous speech" .)
