Temporal -ttua: After Doing (tehtyäni)

If the -essa temporal means "while X was going on", its partner -ttua/-tyä means "after X had happened". Where -essa locks two events to the same moment, -ttua stacks them in sequence: the -ttua event finishes, then the main clause happens. Syötyäni lähdin — "after I had eaten, I left". This is the anterior counterpart in Finnish's pair of non-finite temporal clauses, and like its partner it is compact, tenseless and characteristic of edited prose (formal / literary).

Anteriority: "after" as one word

The construction takes the past passive participle (syöty, tultu, tehty), puts it in the partitive (syötyä, tultua, tehtyä), and adds a possessive suffix naming the doer. The result reads as "after (subject) had done":

Syötyäni lähdin heti töihin.

After I had eaten, I left for work at once.

Luettuaan kirjan hän palautti sen kirjastoon.

After reading the book, he returned it to the library.

Nähtyään elokuvan he keskustelivat siitä pitkään.

After seeing the film, they discussed it for a long time.

Despite being built on the passive participle, the clause is not passive in meaning — the possessive suffix supplies a perfectly ordinary personal subject (-ni = "I", -an = "he"). The passive participle is simply the raw material the construction is carved from; do not translate syötyäni as "after being eaten".

Otettuaan lääkkeen hän tunsi olonsa paremmaksi.

After taking the medicine, he felt better.

Tultuamme kotiin huomasimme, että ovi oli auki.

After we got home, we noticed the door was open.

💡
The -ttua form already contains the completion — it is Finnish's "having done" — so you never prop it up with an auxiliary. Syötyäni by itself means "having eaten / after I had eaten"; there is no olla ("to have/be") to add. A learner who reaches for a compound like oltuani syönyt has invented a construction Finnish simply does not have.

Different subject → genitive

If the doer of the -ttua action is not the main-clause subject, it appears in the genitive — a noun with no possessive suffix, a pronoun with both genitive and suffix:

Vieraiden lähdettyä siivosimme keittiön.

After the guests had left, we cleaned the kitchen.

Hänen lähdettyään huone tuntui tyhjältä.

After he left, the room felt empty.

Sateen lakattua lähdimme kävelylle.

After the rain had stopped, we went for a walk.

Vieraiden and sateen are genitives with a bare lähdettyä / lakattua; the pronoun in hänen lähdettyään carries both the genitive hänen and the suffix -än. This is the identical same-vs-different logic that governs the referative and the -essa clause.

-essa vs -ttua: the minimal contrast

The two constructions differ by a single dimension — simultaneous vs anterior — and Finnish keeps them apart with different builds. Line them up:

While (simultaneous)After (anterior)
tullessani — as I was comingtultuani — after I had come
syödessäni — while I was eatingsyötyäni — after I had eaten
built on 2nd infinitive, inessive -essabuilt on past passive participle, partitive -ttua

Tullessani kotiin kuulin puhelimen soivan.

As I was coming home, I heard the phone ringing.

Tultuani kotiin soitin heti äidille.

After I got home, I called my mother right away.

💡
Both temporal clauses hide the subject in a possessive suffix, not a pronoun — that is what makes them fully non-finite and so compact. English cannot copy this: "after I had eaten" always needs an explicit "I" and a finite "had". Finnish packs subject, tense-relation and verb into the single word syötyäni.

Building the form: off the past passive participle

Form -ttua from the past passive participle, not the lemma — that is where the -tt-/-t- geminates, gradation and harmony are already settled. Take the participle, make it partitive (add -a/-ä by harmony), then add the suffix:

VerbPast passive participle
  • partitive + suffix
syödäsyötysyötyäni
tullatultutultuaan
nähdänähtynähtyään (front → -ä)
ottaaotettuotettuaan
lähteälähdettylähdettyään

Harmony runs through the whole tail: back-vowel tultua → tultuaan, front-vowel nähtyä → nähtyään. Keep the participle's geminate — it is otettuaan, never otetuaan.

Common Mistakes

❌ Tullessani kotiin join heti kahvia.

Incorrect if you mean 'after' — -essa is 'while'; 'after I came home' is tultuani.

✅ Tultuani kotiin join heti kahvia.

After I got home, I drank coffee right away.

❌ Syötyä lähdin töihin.

Incorrect — same subject needs the possessive suffix: syötyäni.

✅ Syötyäni lähdin töihin.

After I had eaten, I left for work.

❌ Vieraat lähdettyä siivosimme keittiön.

Incorrect — a different subject must be genitive: vieraiden.

✅ Vieraiden lähdettyä siivosimme keittiön.

After the guests had left, we cleaned the kitchen.

❌ Otetuaan lääkkeen hän parani.

Incorrect — keep the participle's geminate: otettuaan.

✅ Otettuaan lääkkeen hän parani.

After taking the medicine, he recovered.

Key Takeaways

  • -ttua/-tyä means "after (having done)" — the anterior partner of the simultaneous -essa "while".
  • Build it on the past passive participle, made partitive, plus a possessive suffix naming the doer: syötyäni, tultuaan, lähdettyään.
  • Despite the passive participle, the meaning is active — the suffix supplies the personal subject.
  • Different subject → genitive: vieraiden lähdettyä, hänen lähdettyään.
  • Keep geminates and harmony from the participle: otettuaan (not otetuaan), nähtyään (front vowel).
