Shout about Vera (4)
I believe the answer is:
rave
'shout' is the definition.
(thesaurus)
'about vera' is the wordplay.
'about' indicates anagramming the letters.
'vera' with letters rearranged gives 'RAVE'.
(Other definitions for rave that I've seen before include "Rage" , "Rant about an all-night dance party?" , "Talk with extreme enthusiasm or wild delirium" , "Modern youth dance - sounds hysterical" , "Fume" .)
