宗教 (zōngjiào) means 'religion' — a system of beliefs, practices, and institutions centered on spiritual or sacred matters. The character 宗 (zōng) means 'ancestral', 'main', or 'origin', suggesting something foundational or authoritative; 教 (jiào) means 'teaching' or 'doctrine'. Together, they convey the idea of an authoritative, time-honored teaching — often tied to faith, worship, ethics, and community. In Chinese, 宗教 is a neutral, formal term used in academic, legal, and public contexts.

This word applies broadly to organized world religions (e.g., Christianity, Buddhism, Islam) as well as indigenous or traditional belief systems. It appears frequently in discussions about freedom of belief, cultural heritage, education, and social policy. Unlike English 'religion', 宗教 rarely carries colloquial or ironic connotations — it’s not used playfully (e.g., 'my religion is coffee') unless marked by explicit context or quotation.
