Nothing stops Vermeer being represented for all time (8)
I believe the answer is:
evermore
'for all time' is the definition.
(thesaurus)
'nothing stops vermeer being represented' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'stops' is an insertion indicator (stopping can mean blocking a gap).
'being represented' indicates an anagram.
'vermeer' with letters rearranged gives 'evermre'.
'o' going into 'evermre' is 'EVERMORE'.
(Other definitions for evermore that I've seen before include "Eternally" , "(For) perpetuity" , "To all eternity" , "unceasingly" , "Forever (literary)" .)
