Victoria wasn't a married American journalist (6)
I believe the answer is:
amused
'victoria wasn't' is the definition.
(Queen Victoria supposedly said 'we are not amused')
'a married american journalist' is the wordplay.
'married' becomes 'm'.
'american' becomes 'us' (abbreviation for United States).
'journalist' becomes 'ed' (short for editor).
'a'+'m'+'us'+'ed'='AMUSED'
(Other definitions for amused that I've seen before include "Kept someone entertained" , "Victoria reputedly wasn't" , "Mildly entertained by Medusa" , "happily occupied" , "Pleasantly occupied" .)
