Tried again before satisfactorily taking part (5)
I believe the answer is:
resat
'tried again before satisfactorily taking part' is the definition.
The definition suggests a verb in its base form which matches the answer.
'again before satisfactorily taking part' is the wordplay.
'taking part' indicates a hidden word.
'RESAT' is hidden within 'again before satisfactorily'.
Can you help me to learn more?
(Other definitions for resat that I've seen before include "went back to the paper" , "did test again" , "was tested again" , "Tried to pass again" , "Took (exam) again" .)
