An old Pope free from sin (8)
I believe the answer is:
innocent
This clue might be a double definition.
'an old pope' is the first definition.
'innocent' can be an answer for 'pope' (I've seen this before). I'm not sure about the 'an old' bit.
'free from sin' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for innocent that I've seen before include "Pope" , "Without blame or guilt" , "Without blame or without guile" , "Free from evil or guilt" , "Guiltless or guileless" .)
