also: せいはい
noun
Archaic and literary term for one's peers or companions. Not used in modern everyday speech; encountered mainly in historical or classical texts.
古い書物には「儕輩と語らう」といった表現が見られる。
In old books, expressions like 'converse with one's comrades' can be found.
Alternate reading; even rarer than さいはい.
The exact derivation is uncertain; the kanji 儕 (companion) and 輩 (fellow) combine to convey the meaning of 'peers' or 'comrades'.
