One worries about uncontrolled movement on new currency (8)
I believe the answer is:
neurotic
'one worries about uncontrolled' is the definition.
I can't judge whether this definition defines the answer.
'movement on new currency' is the wordplay.
'movement' becomes 'tic' (an involuntary physical movement).
'on' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'currency' becomes 'euro' (currency of the Eurozone).
'n'+'euro'='neuro'
'tic' put after 'neuro' is 'NEUROTIC'.
Can you help me to learn more?
(Other definitions for neurotic that I've seen before include "Very nervy" , "I counter in being subject to abnormal anxieties" , "Over-anxious" , "obsessive character" , "I counter, being subject to abnormal anxiety" .)
