Isle has better scripture studies (5)
I believe the answer is:
capri
'isle' is the definition.
(Italian island)
'better scripture studies' is the wordplay.
I cannot quite see how this works, but
'better' could be 'cap' (both can mean to beat somebody else's attempt) and 'cap' is found in the answer.
'scripture' could be 'ri' (I've seen this in other clues) and 'ri' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'has' acts as a link.
Can you help me to learn more?
(Other definitions for capri that I've seen before include "Greek island" , "Mediterranean island" , "Romantic and expensive island in Bay of Naples" , "I carp about the island" , "Location for holiday" .)
