Brief experience of rogue state (5)
I believe the answer is:
taste
'brief experience' is the definition.
(a taste of something is a brief experience with it)
'rogue state' is the wordplay.
'rogue' indicates an anagram.
'state' is an anagram of 'TASTE'.
'of' acts as a link.
(Other definitions for taste that I've seen before include "Preference" , "Sample - discrimination" , "Sensation in the mouth caused by food" , "Sense showing refinement" , "Sample the flavour" .)
