A short pastoral poem from New York starts to inspire daughter's youthful love (4)
I believe the answer is:
idyl
'a short pastoral poem from new york' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'starts to inspire daughter's youthful love' is the wordplay.
'starts to' says to take the initial letters.
The initial letters of 'inspire daughters youthful love' is 'IDYL'.
Can you help me to learn more?
(Another definition for idyl that I've seen is " Episode of pastoral or romantic charm".)
