Passive voice The so-called Finnish passive is impersonal and unipersonal, that is, it only appears in one form regardless of who is implicitly understood to be the performer of the action. In that respect, it could be described as a "fourth person" since there is no way of connecting the action performed with a particular agent (except for some nonstandard forms; see below). It is called "passive" for historical reasons in imitation of Swedish and Latin grammars, but this term is in fact incorrect because the object of an active sentence remains an object in the equivalent Finnish "passive" sentence, in other words, the Finnish "passive" sentence is in fact active. In languages with true passives, an active sentence's object becomes the subject in the equivalent passive sentence. Active: "we will arrest him" => passive: "he will be arrested".
