Type 1 is the largest and most important Finnish verb class — the one you meet on day one and use in almost every sentence. Its infinitives end in a vowel + a/ä, that is, in two vowels: puhua, asua, sanoa, lukea, ostaa, antaa, ottaa. The good news is that Type 1 is also the most regular: you form the present stem by simply dropping the final -a/-ä, and the six personal endings attach straight onto the vowel that is left. Two things need watching — the third-person vowel doubling, and consonant gradation — and this page drills both.
Building the stem and the paradigm
Drop the final -a/-ä and you have the stem: puhua → puhu-, asua → asu-, sanoa → sano-. Then add the endings. Here is puhua ("to speak") in full:
| Person | Form | Meaning |
|---|---|---|
| minä | puhun | I speak |
| sinä | puhut | you speak |
| hän | puhuu | he/she speaks |
| me | puhumme | we speak |
| te | puhutte | you (pl.) speak |
| he | puhuvat | they speak |
Puhun töissä koko päivän, joten illalla haluan vain olla hiljaa.
I talk all day at work, so in the evening I just want to be quiet.
Missä sinä asut nykyään?
Where do you live these days?
Isä sanoo aina saman vitsin, kun tulemme kylään.
Dad always tells the same joke when we come to visit.
The third person doubles the final vowel
This is the defining feature of Type 1 (and Type 3). The third-person singular adds no consonant; instead it lengthens the final stem vowel. So puhu- becomes puhuu, sano- becomes sanoo, asu- becomes asuu, luke- becomes lukee. Forgetting this and leaving the bare stem (*hän puhu) is the most common Type 1 error for English speakers.
| Verb | Stem | 3rd sg. (hän) |
|---|---|---|
| puhua (speak) | puhu- | puhuu |
| asua (live) | asu- | asuu |
| sanoa (say) | sano- | sanoo |
| lukea (read) | luke- | lukee |
Hän asuu vielä vanhempiensa luona, mutta muuttaa pian omaan asuntoon.
She still lives with her parents, but she's moving into her own place soon.
Poika lukee sarjakuvia peiton alla taskulampun valossa.
The boy reads comics under the blanket by flashlight.
When the stem already ends in -a or -ä, the doubling just produces -aa/-ää — which happens to look identical to the infinitive. For ostaa ("to buy", stem osta-), the third person is ostaa, and for antaa, the third person is antaa. The infinitive and the hän-form are homophones for these verbs; context tells them apart.
Consonant gradation: weak in four persons, strong in two
Many Type 1 verbs contain a consonant that undergoes gradation. The rule is beautifully regular once you see it: the third person (singular and plural) keeps the strong grade of the infinitive, and the other four persons weaken. This is because the endings -n, -t, -mme, -tte each close the stem syllable, and a closed syllable forces the weak grade; the vowel-final third person leaves the syllable open, so the strong grade survives.
Watch antaa ("to give"), where nt weakens to nn:
| Person | Form | Grade |
|---|---|---|
| minä | annan | weak (nn) |
| sinä | annat | weak (nn) |
| hän | antaa | strong (nt) |
| me | annamme | weak (nn) |
| te | annatte | weak (nn) |
| he | antavat | strong (nt) |
And ottaa ("to take"), where the geminate tt weakens to a single t:
| Person | Form | Grade |
|---|---|---|
| minä | otan | weak (t) |
| sinä | otat | weak (t) |
| hän | ottaa | strong (tt) |
| me | otamme | weak (t) |
| te | otatte | weak (t) |
| he | ottavat | strong (tt) |
Otan aina kahvin mustana, ilman maitoa ja sokeria.
I always take my coffee black, without milk or sugar.

Hän ottaa bussin numero seitsemän joka aamu.
She takes the number seven bus every morning.
Luen lehteä ja juon teetä, kun vaimo vielä nukkuu.
I read the paper and drink tea while my wife is still asleep.
The verb lukea deletes its k entirely in the weak grade (luke- → lue-), so "I read" is luen, never *lukean. Carrying the infinitive's consonant through every person is the classic gradation slip.
Harmony still applies
The third-person-plural ending obeys vowel harmony just as everywhere else: a back-vowel stem takes -vat (puhuvat, ostavat, antavat), a front-vowel stem takes -vät. For an -ä verb such as kysyä ("to ask", stem kysy-), it is kysyvät, not *kysyvat.
Toimittajat kysyvät ministeriltä samat kysymykset joka viikko.
The journalists ask the minister the same questions every week.
Common Mistakes
❌ Hän puhu suomea todella hyvin.
Incorrect — Type 1 doubles the vowel in the third person: puhuu.
✅ Hän puhuu suomea todella hyvin.
She speaks Finnish really well.
❌ Antan sinulle avaimet huomenna.
Incorrect — antaa weakens nt → nn in the first person: annan.
✅ Annan sinulle avaimet huomenna.
I'll give you the keys tomorrow.
❌ Lukean lehteä joka aamu bussissa.
Incorrect — lukea drops the k in the weak grade: luen.
✅ Luen lehteä joka aamu bussissa.
I read the paper every morning on the bus.
❌ He ottavät taksin lentokentälle.
Incorrect — otta- is a back-vowel stem, so the plural is -vat: ottavat.
✅ He ottavat taksin lentokentälle.
They're taking a taxi to the airport.
Key Takeaways
- Stem: drop the final -a/-ä from the infinitive (puhua → puhu-, ostaa → osta-).
- Third person: doubles the final stem vowel (puhuu, sanoo, lukee); if the stem already ends in -a, the hän-form matches the infinitive (antaa, ostaa).
- Gradation: third person strong, the other four persons weak (ottaa but otan; antaa but annan; lukee but luen). See gradation in verbs.
- The plural -vat/-vät always harmonises with the stem.
