Indecision shown by Verdi there (6)
I believe the answer is:
dither
'indecision' is the definition.
(I've seen this before)
'shown by verdi there' is the wordplay.
'shown by' indicates a hidden word.
'DITHER' is hidden within 'verdi there'.
(Other definitions for dither that I've seen before include "Vacillate, be indecisive" , "Shilly-shally" , "Keep hesitating" , "Waver, vacillate" , "Stew" .)
