Watch series about shocking medical treatment (8)
I believe the answer is:
spectate
'watch series' is the definition.
'spectate' can be an answer for 'watch' (spectating is a kind of watching). I am not certain of the 'series' bit.
'about shocking medical treatment' is the wordplay.
'about' indicates putting letters inside.
'shocking medical' becomes 'spate' (I can't justify this - if you can you should believe this answer much more).
'treatment' becomes 'ECT' (ECT is an example).
'spate' placed around 'ect' is 'SPECTATE'.
Can you help me to learn more?
(Other definitions for spectate that I've seen before include "Watch (a game, etc)" , "Be a viewer, at a sports event perhaps" , "Be an onlooker" , "Observe" , "View" .)
