Isle having better scripture studies (5)
I believe the answer is:
capri
'isle' is the definition.
(Italian island)
'better scripture studies' is the wordplay.
I cannot really understand how this works, but
'better' could be 'cap' (both can mean to beat somebody else's attempt) and 'cap' is present in the answer.
'scripture' could be 'ri' (I've seen this in other clues) and 'ri' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'having' is the link.
Can you help me to learn more?
(Other definitions for capri that I've seen before include "found in Tyrrhenian location" , "Mediterranean island" , "Italian isle" , "Romantic and expensive island in Bay of Naples" , "Island off Italy" .)
