Nice point about establishment (9)
I believe the answer is:
inception
'establishment' is the definition.
(I've seen this before)
'nice point about' is the wordplay.
'about' indicates an anagram.
'nice'+'point'='nicepoint'
'nicepoint' is an anagram of 'INCEPTION'.
(Other definitions for inception that I've seen before include "Opening" , "Establishment" , "Starting point" , "start" , "Beginning" .)
