immature person; person of low status
Archaic term for a callow or low-ranking person; not used in modern Japanese outside historical or literary contexts.
In old documents, 生者 can be read なまもの and refer to an immature person.
The historical derivation is uncertain; the spelling 生者 is conventionally associated with 'living person' in Buddhist contexts, but the reading なまもの and the meaning 'immature/low-status person' appear to be an archaic specialized usage.
