Wierni

Wierni is a Polish word that functions as both an adjective meaning faithful or loyal, and as a plural noun meaning the faithful or believers. In religious contexts it refers to people who profess and practice a faith—most commonly within Christian communities. In Catholic Poland, the phrase "wierni Kościoła" is used to denote the faithful or laity of the Church. Beyond strictly religious use, "wierni" can describe loyal supporters of a group, organization, or movement.

The term derives from the verb "wierzyć" (to believe) and the adjective "wierny" (faithful, loyal). As a noun, "wierni" is usually used to designate a group of believers rather than an individual. The word appears in liturgical texts, sermons, church documents, and in journalism or literature when referring to a community of adherents.

In usage, "wierni" is not a proper noun and is typically written in lowercase unless it appears at the beginning of a sentence. Its sense can be broadened from religious contexts to describe loyal followers or supporters of various movements or causes, functioning as a generic designation for a collective of people united by belief or allegiance.
