layperson; ordinary person (not a priest)
Specifically used in religious contexts to refer to someone who has not entered the priesthood or monastic life; a layperson.
The difference between a monk and a layperson lies in the precepts.
俗人 means a layperson living outside religious orders, the opposite of 僧, someone who has taken up monastic life.
俗人 is an ordinary, worldly person caught up in mundane desires, the direct opposite of a 仙人 who is detached from earthly concerns.
Compound of 俗 (ぞく, 'vulgar, worldly') and 人 (じん, 'person'). The exact historical derivation is uncertain, but the word has been used in both secular and Buddhist contexts.
