Passiivilaji

Passiivilaji is a term used in linguistics to denote a class of verb forms that realize the passive voice in a given language. It refers to the mechanism by which an event or action is described as affecting the subject of the sentence rather than the agent performing the action. In languages that separate voice and mood through morphology, passiivilaji typically marks the action as having no overt agent or as being described from the perspective of the affected participant.

In Nordic and Finnic linguistic traditions, passiivilaji is often discussed in relation to the Finnish passive system, where verbs can appear in passive forms that generalize statements or depersonalize actions. For example, a sentence like Kirja luetaan can be translated as The book is read, with the agent either unknown or unimportant. Passiivilaji can also include periphrastic or derivational passive constructions found in various languages, where auxiliary verbs, participles, or verbal supplements convey the same basic function of passivation.

Morphology and syntax of passiivilaji vary across languages. Some languages use dedicated suffixes or inflections on the verb to signal passive voice, while others rely on periphrastic constructions or impersonal forms. Passiivilaji often contrasts with active forms and, depending on the language, with other voice systems such as ergative or middle constructions. It frequently interacts with word order, evidentiality, and agent expression, influencing how agents are introduced or omitted.

Usage and typology: passiivilaji is typical in formal, general, or backgrounded statements, where the focus is on the action or its patient rather than who performs it. See also: passive voice, voice systems, Finnish grammar.
