Kastetut

Kastetut is a Finnish term meaning “the baptized.” It is the plural form of kastettu, the past passive participle of the verb kastaa, which means to baptize. As a noun or as an adjective, kastettu describes someone who has undergone baptism, and kastetut refers to a group of such people. In everyday language, kastettu is used for a singular baptized person, while kastetut is used for multiple individuals, for example in phrases like kastetut lapset (baptized children) or kastetut ihmiset (the baptized people).

Usage of the term is most common in religious, historical, or genealogical contexts. It often appears in church records, baptismal lists, or liturgical writings, where the authors refer to those who have received Christian baptism. In ordinary modern prose, speakers may simply say someone is "baptized" rather than using the participial forms, but kastetut can still be found in formal or archival texts.

Etymology: kastetut is formed from the noun kaste (baptism) with the past passive participle suffix -ttu, producing kastettu (singular) and kastetut (plural). Related forms include kastaa (to baptize) and kaste (baptism). The term thus reflects Finnish word-formation patterns for derived adjectives and nouns tied to religious rites.
