I believe the answer is:
amused
'what queen victoria was not' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for amused that I've seen before include "Queen Victoria wasn't!" , "Kept someone entertained" , "Victoria reputedly wasn't" , "Beguiled" , "Tickled pink" .)
