Eternal child's games provoked parent (5,3)
I believe the answer is:
peter pan
'eternal child's games provoked parent' is the definition.
I can't judge whether this defines the answer.
'games provoked parent' is the wordplay.
I cannot quite see how this works, but
'games' could be 'pe' (abbreviation for Physical Education) and 'pe' is present in the answer.
an anagram of 'parent' is 'terpan' which is within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for peter pan that I've seen before include "Youth forever" , "voyager to Never Never Land" , "Child that never grows old" , "Barrie's youthful hero" , "Boyish creation of J.M. Barrie" .)
