chief priest; resident priest
Specifically the head priest who resides at and oversees a Buddhist temple. Not a general term for any monk.
The chief priest of that temple chants sutras early every morning.
The atmosphere of the temple changed after the resident priest was replaced.
Compound of 住 (reside) and 僧 (monk/priest), literally 'residing priest'. The exact historical derivation is uncertain, but the spelling is conventionally associated with the meaning of a priest who lives at and manages a temple.
