Loathe journalist’s twisted examination (6)
I believe the answer is:
detest
'loathe' is the definition.
(thesaurus)
'journalist's twisted examination' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'twisted' shows that the letters should be reversed in order.
'examination' becomes 'test' ('test' can be a synonym of 'examination').
'ed' written backwards gives 'de'.
'de'+'test'='DETEST'
(Other definitions for detest that I've seen before include "Find repulsive" , "Deplore" , "Greatly hate" , "Hate a lot" , "Dislike intensely, loathe" .)
