A participle is a verb wearing an adjective's clothes. Finnish has a rich set of them, and they do an enormous amount of work: they let you compress a whole relative clause ("the train that is arriving") into a single word in front of a noun (saapuva juna), and the active ones are the building blocks of the perfect tenses (olen tehnyt). This page is the map of the whole participle system — it names each form, shows the grid they fall into, and points to the page that treats each one in depth.
The six participles
Finnish has four "core" participles arranged in a neat two-by-two grid of voice (active vs. passive) and tense (present vs. past), plus two more that fall outside the grid: the agent participle and the negative participle.
| Participle | Suffix | Example (puhua) | Rough meaning |
|---|---|---|---|
| Present active | -va / -vä | puhuva | speaking / who speaks |
| Past active | -nut / -nyt (pl. -neet) | puhunut | (having) spoken |
| Present passive | -tava / -ttava | puhuttava | to be spoken / that must be spoken |
| Past passive | -tu / -ttu | puhuttu | spoken (by someone) |
| Agent | -ma / -mä | puhuma | spoken by X (minun puhumani) |
| Negative | -maton / -mätön | puhumaton | unspoken / not speaking |
The active/passive split is the same one you know from English ("the man eating" vs. "the food eaten"), and the present/past split is about whether the action is ongoing or completed. The two extras have no tidy English label: the agent participle expresses "X made by someone" (äidin tekemä ruoka), and the negative participle is the "un-" adjective (tekemätön "undone, not done").
They are adjectives: they decline and agree
This is the point English speakers most often miss. A Finnish participle is a full adjective: it takes the case and number of the noun it modifies, exactly like iso ("big") or punainen ("red"). So nukkuva ("sleeping") becomes nukkuvan, nukkuvaa, nukkuvassa as the noun's case demands.
Nukkuvaa lasta ei kannata herättää.
It's not worth waking a sleeping child.
Väsyneet matkustajat nukahtivat heti junaan.
The tired passengers fell asleep on the train at once.
In the first sentence nukkuvaa is in the partitive to agree with lasta; in the second väsyneet is in the plural to agree with matkustajat. This agreement is what makes participles feel so different from their English cousins, which never change shape. How a participle competes with a full joka-clause is treated on the participle vs. clause page.
Present active -va/-vä: an ongoing action
Built on the strong stem + -va/-vä, this is the "…-ing" adjective: an action in progress or a general characteristic. Tuleva famously also means "coming = future" (tuleva viikko, "the coming week").
Ohi kulkeva juna herätti koko talon.
The passing train woke the whole house.

Past active -nut/-nyt: a completed action
Built with -nut/-nyt (singular) and -neet (plural), this is the completed-action adjective — and the very same form that builds the perfect and pluperfect with olla.
Olen jo lukenut tämän kirjan kahdesti.
I've already read this book twice.
Maahan pudonneet lehdet peittivät koko pihan.
The leaves that had fallen to the ground covered the whole yard.
The first sentence uses it as a perfect-tense verb (olen lukenut), the second as a plain adjective (pudonneet lehdet). Both jobs, one form — see the past active participle and the past participle in the perfect.
The passive participles: -ttava and -ttu
The present passive -tava/-ttava means "to be X-ed," and it is also the standard way to express necessity ("must be done"): tämä on tehtävä = "this must be done."
Tämä lasku on maksettava ensi viikkoon mennessä.
This bill must be paid by next week.
The past passive -tu/-ttu means "X-ed (by someone)" and builds the passive perfect (on tehty).
Kaikki liput on jo myyty.
All the tickets have already been sold.
Notice the gradation and vowel changes these forms trigger: tehdä → tehtävä / tehty, ottaa → otettava / otettu, syödä → syötävä / syöty. Get the doubled tt and the ä/ö right — they are phonemic.
Agent -ma/-mä and negative -maton/-mätön
The agent participle says who performed the action, with the doer in the genitive in front: äidin leipoma leipä = "the bread (that) mother baked." The negative participle is the "un-" adjective, formed with -maton/-mätön.
Äidin leipoma pulla tuoksui koko keittiössä.
The bun mother had baked filled the whole kitchen with its scent.
Tuntematon numero soitti keskellä yötä.
An unknown number called in the middle of the night.

Common Mistakes
❌ Nukkuva lasta ei kannata herättää.
Incorrect — the participle must agree with its noun; lasta is partitive, so it's nukkuvaa lasta.
✅ Nukkuvaa lasta ei kannata herättää.
It's not worth waking a sleeping child.
❌ Olen lukea tämän kirjan.
Incorrect — the perfect is built with the past active participle, not the infinitive: olen lukenut.
✅ Olen lukenut tämän kirjan.
I have read this book.
❌ Kaikki liput on myyneet.
Incorrect — the passive perfect uses the past passive participle myyty, not the active -neet form.
✅ Kaikki liput on myyty.
All the tickets have been sold.
❌ Äidin tekemä ruokaa oli hyvää.
Incorrect — as the subject, both the participle and its noun stay nominative: äidin tekemä ruoka.
✅ Äidin tekemä ruoka oli hyvää.
The food mother made was good.
Key Takeaways
- Finnish has four core participles in a voice × tense grid — present/past active (puhuva, puhunut) and present/past passive (puhuttava, puhuttu) — plus the agent (-ma) and negative (-maton).
- Every participle is an adjective: it declines and agrees with its noun in case and number.
- The active participles build the compound tenses (olen puhunut, on puhuttu).
- Watch gradation and the tt/t and ä/ö alternations (tehtävä, tehty, otettu, syöty) — they are exact and meaning-bearing.
