Supply hard-up state with no exposure to outside world (6)
I believe the answer is:
purdah
'state with no exposure to outside world' is the definition.
I can't judge whether this defines the answer.
'supply hard-up' is the wordplay.
'supply' indicates anagramming the letters (in a supple way).
'hard'+'up'='hardup'
'hardup' anagrammed gives 'PURDAH'.
Can you help me to learn more?
(Other definitions for purdah that I've seen before include "Seclusion of women as religious practice" , "State of social isolation" , "Hindu or Muslim seclusion of women" , "Muslim and Hindu custom of keeping women secluded" , "System in Muslim communities of keeping women from the sight of men" .)
