Confesses to the priest, who looks disapproving (6)
I believe the answer is:
frowns
'looks disapproving' is the definition.
I can't judge whether this defines the answer.
'confesses to the priest' is the wordplay.
'confesses' becomes 'owns' (I've seen this before).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the priest' becomes 'fr' (abbreviation for father).
'owns' put after 'fr' is 'FROWNS'.
'who' is the link.
Can you help me to learn more?
(Other definitions for frowns that I've seen before include "Shows displeasure" , "Scowls" .)
