The past active participle is one of the most useful single forms in Finnish. You need it for the perfect (olen puhunut), for the pluperfect (olin puhunut), and for the negative past (en puhunut). Learn to build it once and three tenses open up at the same time. The form has two shapes to remember — a singular -nut/-nyt and a plural -neet — plus one wrinkle that catches learners out: when the verb stem ends in a consonant, the -n- of -nut fuses with it.
The basic form: -nut / -nyt (singular), -neet (plural)
Take the verb's infinitive stem, and attach -nut/-nyt for a singular subject or -neet for a plural subject. The singular follows vowel harmony — -nut after a back-vowel verb, -nyt after a front-vowel verb — while the plural -neet never changes.
For verbs whose stem ends in a vowel (the -a/-ä verbs and the -da/-dä verbs), nothing fuses; the ending just clicks on:
| Verb | Singular | Plural |
|---|---|---|
| puhua (speak) | puhunut | puhuneet |
| ostaa (buy) | ostanut | ostaneet |
| syödä (eat) | syönyt | syöneet |
| tehdä (do) | tehnyt | tehneet |
| nähdä (see) | nähnyt | nähneet |
| voida (can) | voinut | voineet |
Note syönyt, not *syönut: syödä is a front-vowel verb, so harmony demands -nyt. This is the harmony trap on the singular participle.
Oletko syönyt jo, vai laitanko meille jotain?
Have you eaten yet, or should I make us something?
En ole vielä ostanut lippuja konserttiin.
I haven't bought the concert tickets yet.
When the stem ends in a consonant, -n- assimilates
The -la/-lä, -na/-nä, -ra/-rä, -sta/-stä verbs (traditionally "type 3") have stems ending in a consonant — l, n, r, or s. Here the -n- of -nut does not survive as n; it assimilates to the preceding consonant, doubling it. This is the wrinkle that most textbooks bury in a footnote, and it is exactly where learners produce *tulnut instead of the correct tullut.
| Verb | Stem ends in | Singular | Plural |
|---|---|---|---|
| tulla (come) | l | tullut | tulleet |
| mennä (go) | n | mennyt | menneet |
| purra (bite) | r | purrut | purreet |
| nousta (rise) | s | noussut | nousseet |
| pestä (wash) | s | pessyt | pesseet |
| juosta (run) | s | juossut | juosseet |
Read them as the same rule applied to different consonants: tul + nut → tullut (l swallows the n), men + nyt → mennyt (n + n), pur + nut → purrut (r + r), nous + nut → noussut (s + s). The plural does the same: tul + neet → tulleet, nous + neet → nousseet.
Juna on jo tullut, mutta Anna ei ole vielä noussut asemalla junaan.
The train has already come, but Anna hasn't got on it at the station yet.

The kids have run around outside all afternoon.
Contracted verbs: -nnut / -nnyt
The contracted verbs — -ata/-ätä, -ita/-itä, -eta/-etä (types 4–6, such as haluta, tarvita, paeta) — have an underlying stem-final consonant that assimilates the -n- into a double -nn-. Their participle therefore ends in -nnut/-nnyt (singular) and -nneet (plural):
| Verb | Singular | Plural |
|---|---|---|
| haluta (want) | halunnut | halunneet |
| tavata (meet) | tavannut | tavanneet |
| tarvita (need) | tarvinnut | tarvinneet |
| paeta (flee) | paennut | paenneet |

Singular vs. plural: match the subject
Because the participle agrees in number, a plural subject needs -neet (or -nneet), not the singular. Reusing the singular form under a plural subject — *olemme tullut for olemme tulleet — is the most persistent participle error for English speakers, whose "have come" gives no clue about number.
| Subject | tulla | syödä | nousta |
|---|---|---|---|
| singular (minä/sinä/hän) | tullut | syönyt | noussut |
| plural (me/te/he) | tulleet | syöneet | nousseet |
Hän on noussut ylös, mutta muut ovat vielä sängyssä.
She's got up, but the others are still in bed.
Common Mistakes
❌ Bussi on tulnut jo pysäkille.
Incorrect — the -n- assimilates to the l: tullut, not tulnut.
✅ Bussi on tullut jo pysäkille.
The bus has already come to the stop.
❌ Me olemme tullut ajoissa.
Incorrect — a plural subject needs the plural participle: tulleet.
✅ Me olemme tulleet ajoissa.
We've arrived on time.
❌ Oletko syönut jo aamiaisen?
Incorrect — syödä is a front-vowel verb: syönyt, not syönut.
✅ Oletko syönyt jo aamiaisen?
Have you already eaten breakfast?
❌ Aurinko on nousnut jo kello viisi.
Incorrect — nousta assimilates s + n → ss: noussut, not nousnut.
✅ Aurinko on noussut jo kello viisi.
The sun rose as early as five o'clock.
Key Takeaways
- Singular participle: -nut (back) / -nyt (front); plural participle: -neet — always, no harmony.
- Vowel-stem verbs just add the ending: puhunut, syönyt, tehnyt, ostaneet.
- Consonant-stem verbs assimilate the -n-: tullut (l), mennyt (n), purrut (r), noussut / pessyt / juossut (s).
- Contracted verbs give -nnut/-nnyt: halunnut, tarvinnut, paennut.
- Match the participle to the subject's number — olemme tulleet, never *olemme tullut.
