Holiday interrupted by ailment originally is taken another time (5)
I believe the answer is:
resat
'taken another time' is the definition.
The definition suggests a verb in its base form which matches the answer.
'holiday interrupted by ailment originally' is the wordplay.
'holiday' becomes 'rest' (rest can mean a holiday or break).
'interrupted by' means one lot of letters goes inside another.
'originally' indicates taking the first letters.
The first letter of 'ailment' is 'a'.
'rest' going around 'a' is 'RESAT'.
'is' is the link.
Can you help me to learn more?
(Other definitions for resat that I've seen before include "Took (exam) again" , "did test again" , "Tried to pass again" , "went back to the paper" , "Took another chance to pass" .)
