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' means one lot of letters go next to another (I've seen this in other clues).
'the priest' becomes 'fr'.
'owns' put after 'fr' is 'FROWNS'.
'who' acts as a link.
Can you help me to learn more?
(Other definitions for frowns that I've seen before include "Shows displeasure" , "Scowls" .)
