Prophet is more godly (7)
I believe the answer is:
diviner
'prophet' is the definition.
(thesaurus)
'more godly' is the wordplay.
I cannot really understand how this works, but
'godly' could be 'divine' (synonyms) and 'divine' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' acts as a link.
Can you help me to learn more?
(Other definitions for diviner that I've seen before include "one conjectures" , "More sacred" , "He finds water" , "A soothsayer" , "even more delightful" .)
