baldric

'swordbelt' is the definition.
I can't judge whether this definition defines the answer.

'plain one found in church' is the wordplay.
'plain' becomes 'bald' (both can mean unadorned).
'one' becomes 'i' (Roman numeral).
'found in' indicates putting letters inside.
'church' becomes 'RC' (abbreviation for Roman Catholic).
'i' inserted within 'rc' is 'ric'.
'bald'+'ric'='BALDRIC'

Can you help me to learn more?

(Other definitions for baldric that I've seen before include "Sword belt" , "Sword-belt" , "Strapping swordsman carried" , "Carrier for weapon" , "is under one's belt" .)

I've seen this clue in the Sydney Morning Herald.
