Stacked Temporal Constructions

Level 6

The tehtyä-construction (past temporal clause equivalent) replaces a kun ('when/after') clause to show that one action was completed before another. It is a hallmark of formal, literary, and journalistic Finnish.

How It Works

This construction, known as menneen ajan temporaalinen lauseenvastike, is used to compress information in formal writing. It indicates anteriority—meaning the action in the participle clause happened before the main verb. Crucially, this construction always uses the passive past participle form, but it can be used for both active and passive meanings. Note that this construction can ONLY replace time-related 'kun' clauses, not 'koska' (because) or 'jos' (if).

1. Formation:
The partitive ending -a/-ä (chosen based on vowel harmony) is added to the past passive participle stem. The number of 't's depends on the verb type:

  • Double 't' (-ttu/-tty): Used for Verb Type 1 (lukea → luettua), Type 4 (tavata → tavattua), Type 5 (hallita → hallittua), and Type 6 (vanheta → vanhettua).
  • Single 't' (-tu/-ty): Used for Verb Type 2 (syödä → syötyä) and Type 3 (tulla → tultua).

2. Subject Rules:

  • Same Subject: Use a possessive suffix. Syötyäni lähdin. (After I had eaten, I left.) Note that the 3rd-person possessive suffix is usually -Vn (lengthening the final vowel + n), e.g., tultua + Vn = tultuaan.
  • Different Subject (Noun): The noun is in the genitive case. Auringon laskettua tuli kylmä.
  • Different Subject (Personal Pronoun): The corresponding possessive suffix is mandatory. An explicit pronoun is genitive; first- and second-person pronouns can be omitted, while a third-person pronoun distinguishes a different actor. Hänen tultuaan me söimme.
  • Different Subject (Demonstrative/Non-human Pronoun): The pronoun is in the genitive, but NO possessive suffix is added. Sen tultua valmiiksi... (After it became ready...).
  • Passive Usage: When the construction has a passive meaning, no genitive subject or possessive suffix is used. Syötyä lähdettiin kävelylle. (After eating, people went for a walk.)

3. Object Rule:
In active clauses, the object takes the exact same case as in the corresponding 'kun' clause. This includes the genitive-accusative -n (Syötyään omenan...) or the nominative plural -t (Syötyään omenat...). Partitive objects remain partitive. Personal pronouns as objects must retain their accusative -t ending: Nähtyään minut... (After having seen me...). When this construction is used with a passive meaning, it is almost exclusively used intransitively (without an object).

4. Tense Independence:
The main verb can be in a present-tense form with present or future reference, as the construction only indicates anteriority relative to the main verb. Syötyäni lähden. (After I have eaten, I will leave.)

5. Negation:
This construction cannot be negated. To express a negative temporal relationship, you must use a full kun clause or an ilman että construction.

Reading a Chain
In Pestyään kasvonsa ja juotuaan kupin kahvia hän lähti, both washing and drinking happen before leaving. Their order in the sentence suggests a sequence, but the construction itself only places each before the main event. Repeated suffixes identify the shared actor. With separate actors, repeat each genitive subject: Sateen lakattua ja pilvien hälvettyä.... Prefer separate sentences if several compressed clauses make the timeline or actors hard to follow.

Examples (5)

  1. Pestyään kasvonsa ja juotuaan kupin kahvia hän tunsi itsensä virkeämmäksi.

    After having washed his face and drunk a cup of coffee, he felt more refreshed.

    Word by Word: Having-washed-his face and having-drunk cup coffee-of he felt himself more-refreshed.

    This shows 'stacking' of two temporal constructions to describe a sequence of actions by the same person. Note that 'kasvonsa' and 'kupin' follow specific object rules for these clauses.

  2. Sateen lakattua ja pilvien hälvettyä pääsimme vihdoin jatkamaan matkaa.

    After the rain had stopped and the clouds had cleared, we were finally able to continue the journey.

    Word by Word: Rain-of having-stopped and clouds-of having-cleared we-got finally to-continue journey.

    Here, the subjects (sade, pilvet) are nouns in the genitive case. Because they are nouns, no possessive suffix is used.

  3. Hänen tultuaan kotiin aloimme heti syödä.

    After he had come home, we immediately started to eat.

    Word by Word: His having-come-his home-to we-started immediately to-eat.

    When the subject is a personal pronoun (hänen), the corresponding possessive suffix (-Vn, here -an) must be added to the participle.

  4. Luettuaan kirjan loppuun hän sammutti valot.

    After having read the book to the end, he turned off the lights.

    Word by Word: Having-read-his book-of end-to he turned-off lights.

    In these participle constructions, the total object takes the genitive-accusative form (kirjan), just as it would in a regular 'kun' clause.

  5. Sen tultua valmiiksi aloimme pakata.

    After it became ready, we started to pack.

    Word by Word: Its having-come ready-to we-started to-pack.

    When the subject is a demonstrative or non-human pronoun (sen), it takes the genitive case but strictly does not take a possessive suffix.

Common Mistakes

  • Using the nominative-like object instead of the genitive-accusative object (-n).

    Syötyään aamiainen hän lähti.
    Syötyään aamiaisen hän lähti.

    In these temporal constructions, the total object takes the genitive-accusative form (aamiaisen), exactly as it would in the corresponding 'kun' clause.

  • Forgetting the possessive suffix when the subject is a personal pronoun.

    Hänen tultua kotiin söimme.
    Hänen tultuaan kotiin söimme.

    If the subject is a personal pronoun in the genitive, you must add the corresponding possessive suffix to the participle.

  • Using the nominative case for a different subject.

    Aurinko laskettua tuli pimeää.
    Auringon laskettua tuli pimeää.

    When the subject of the temporal construction is different from the main clause, it must be in the genitive case (Auringon).
