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 in the letters of '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" .)
