Dislike of French examination (6)
I believe the answer is:
detest
'dislike' is the definition.
(to detest is to strongly dislike)
'of french examination' is the wordplay.
'of french' becomes 'de' ('of' in French).
'examination' becomes 'test' (synonyms).
'de'+'test'='DETEST'
(Other definitions for detest that I've seen before include "can't stand" , "Abominate" , "Not like" , "Dislike intensely, think badly of" , "Loathe, hate intensely" .)
