Catholic priest's into outdated belief? (5)
I believe the answer is:
relic
'outdated belief?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'catholic priest's into' is the wordplay.
'catholic' becomes 'RC' (abbreviation for Roman Catholic).
'priest' becomes 'eli' (biblical figure).
'into' is an insertion indicator.
'rc' going around 'eli' is 'RELIC'.
Can you help me to learn more?
(Other definitions for relic that I've seen before include "Ossified survival" , "Survival from earlier times" , "Saint's body part?" , "(Holy) remains" , "Hangover from an earlier time" .)
