Fellow in therapy with restraining order? (6)
I believe the answer is:
curfew
'restraining order?' is the definition.
(I've seen this before)
'fellow in therapy with' is the wordplay.
'fellow' becomes 'F' (abbreviation - of a society etc.).
'in' indicates putting letters inside.
'therapy' becomes 'cure' (cure is a kind of therapy).
'with' becomes 'w' (abbreviation).
'f' put inside 'cure' is 'curfe'.
'curfe'+'w'='CURFEW'
(Other definitions for curfew that I've seen before include "Order restricting time not at home" , "Order restricting movements after a set time" , "Official order restricting people's movements" , "Requirement to be indoors at a set hour" , "Order prohibiting outside activities after a given time" .)
