I'm a little stuck... Click here to teach me more about this clue!

'pariah state's' is the definition.
(state of being made a pariah)

(Other definitions for isolation that I've seen before include "Remoteness" , "Separation, solitariness" , "State of separation, closing off" , "Quarantine; solitude" , "loneliness" .)

I've seen this clue in The Independent.
