Compelling reform of phony movement out of control (8)
I believe the answer is:
hypnotic
'compelling' is the definition.
(I've seen this before)
'reform of phony movement out of control' is the wordplay.
'reform of' indicates an anagram (the letters re-formed in a new order).
'movement' becomes 'tic' (an involuntary physical movement).
'out of' means to remove the last letter (I've seen 'out' mean this).
'control' becomes 'c' (this might be a standard abbreviation which I don't know about).
'tic' with its last letter taken away is 'ti'.
'phony' is an anagram of 'hypno'.
'hypno'+'ti'+'c'='HYPNOTIC'
Can you help me to learn more?
(Other definitions for hypnotic that I've seen before include "Sleeping pill" , "soporific" , "Trance-inducing" , "Sleep-inducing" , "spell-binding" .)
