After thirty, she's finished! (5)
I believe the answer is:
april
'after thirty' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for april that I've seen before include "on her first kid" , "4th month" , "Month of showers and of the Queen's birthday" , "Start of the financial year" , "Part of spring" .)
