Participles as Subjects

This construction, known in Finnish as subjektina toimiva referatiivinen lauseenvastike, condenses a full subordinate clause into a compact phrase. While impersonal forms lean formal and are common in academic and legal registers, the subject-raising forms with perception verbs are ubiquitous in everyday spoken Finnish and casual writing.

1. Structure:

• The Subject: Depending on the main verb, the subject is either in the nominative (subject-raising) or the genitive case (impersonal construction). In impersonal constructions, the genitive subject often follows the main verb, though placement can vary with information structure: Osoittautui hänen puhuneen totta. (It turned out that he had spoken the truth.)
• The Participle: The verb takes a fixed participial form ending in -n, identical in shape to a participle’s genitive. Use the active present participle (-van/-vän) for simultaneous actions and the genitive past participle (-neen) for completed actions. The time reference of the participle is relative to the tense of the main verb (e.g., Näytti satavan means the seeming and raining happened at the same time in the past). In the standard raising and impersonal subject patterns taught here, do not add a possessive suffix to mark the actor.
• Passive and Existential Forms: The construction also supports passive participles (present -tavan/-tävän and past -tun/-tyn, with stem-dependent variants such as tehdyn) to indicate an unspecified actor: Näytti tehdyn virhe. (It seemed a mistake had been made.) Note that the main verb must remain in the active voice (3rd person singular) even when the participle is passive. In existential clauses, the main verb remains in the 3rd person singular, and the subject follows the participle: Näkyi tulevan vettä. (It looked as though it was raining.) An indefinite mass or plural existential subject can be partitive even in an affirmative clause; it is not automatically nominative.

2. Trigger Verbs:
This pattern occurs with 'matrix' verbs that allow a clause to be their subject:

• Perception and Appearance: näyttää, tuntua, kuulua, näkyä, vaikuttaa. These typically function as raising verbs where the subject is nominative: Sinä näytät olevan iloinen. (You seem to be happy.) Crucially, when the subject is raised to the nominative, the main verb must conjugate to agree with it in person and number (e.g., Minä tunnun..., He näyttävät...).
• Emergence and Proof: ilmetä, osoittautua, paljastua. While osoittautua is often used with the translative case, in this construction it is primarily used in impersonal forms where the whole participial phrase acts as the subject.

3. Case of the Participle and Clause Elements:
In this construction, the participle always takes the -n ending (e.g., tulevan, olleen). This is a fixed form for the clause equivalent; it does not follow standard case marking rules for subjects and does not change to the partitive case even if the main verb is negated. Any predicative adjective or noun inside this clause takes its standard case (nominative, or partitive for plurals/mass nouns) rather than remaining strictly in the nominative (e.g., Te näytätte olevan iloisia, Se näyttää olevan vettä). Object case requires attention to the participial construction. With an active main verb and a passive participle, a singular total object preceding that participle is genitive (näytti työn suoritetun). After a passive participle, both genitive and nominative total objects occur: näytti tehdyn virheen ~ virhe. Partitive objects remain possible for indefinite quantities or unbounded actions.

4. Negation:
Negating the main verb denies the appearance or inference: Sade ei näytä alkavan means “The rain does not seem to be starting.” This does not freely encode negation inside the embedded proposition. To say “It seems that he is not coming,” use Näyttää siltä, että hän ei tule. While the participle itself does not change to the partitive case when negated, the subject of an existential clause can change to the partitive in negative sentences (e.g., Näkyi tulevan sade -> Ei näkynyt tulevan sadetta).
