Powerless actor gets suspended (9)
I believe the answer is:
hamstrung
'powerless' is the definition.
(I've seen this before)
'actor gets suspended' is the wordplay.
'actor' becomes 'ham' (ham actor is a kind of actor).
'gets' is a charade indicator (letters next to each other).
'suspended' becomes 'strung' (I've seen this before).
'ham'+'strung'='HAMSTRUNG'
(Other definitions for hamstrung that I've seen before include "Made ineffective" , "Stymied" , "Powerless" , "restricted" , "Crippled" .)
