noun
same race and same language
A formal, somewhat dated term used in historical or political contexts to describe groups sharing ethnic and linguistic identity. Often appears in discussions of nationalism or pan-Asianism.
同種同文の国々が協力して新しい同盟を結んだ。
Countries of the same race and language cooperated to form a new alliance.
A variant with the same meaning; the order of characters is reversed but usage is essentially identical.
Compound of 同種 (same race/kind) and 同文 (same language/script). The exact historical origin is uncertain, but it likely emerged in early modern Japanese political discourse.
