A Finnish finite verb is never neutral about who is doing the action: it carries an ending that names the subject's person and number. Where English relies almost entirely on a separate pronoun (I speak, we speak — the verb barely moves), Finnish folds that information into the verb itself. This page teaches the full six-way agreement pattern, and then the equally important flip side: the handful of sentence types where the verb deliberately stops agreeing and sits in a fixed third-person-singular form.
The six endings
Every present-tense verb takes one of six personal endings. They attach to the verb's present stem:
| Person | Ending | puhua (to speak) | syödä (to eat) |
|---|---|---|---|
| minä (I) | -n | puhun | syön |
| sinä (you sg.) | -t | puhut | syöt |
| hän (he/she) | – | puhuu | syö |
| me (we) | -mme | puhumme | syömme |
| te (you pl.) | -tte | puhutte | syötte |
| he (they) | -vat / -vät | puhuvat | syövät |
The third-person singular has no visible ending; instead the final vowel lengthens (puhu → puhuu). When the stem already ends in a long vowel, nothing changes: syö stays syö. Full details, including the trickier stems, live on Personal Endings.
Minä puhun suomea joka päivä.
I speak Finnish every day.
Me luemme samaa kirjaa.
We're reading the same book.
Lapset lukevat sängyssä salaa taskulampun valossa.
The kids are secretly reading in bed by flashlight.
Notice the last one: the subject lapset is plural, so the verb must be plural too — lukevat, not lukee. A plural subject always forces the -vat/-vät ending in a normal clause.
Hän puhuu, mutta he eivät kuuntele.
He's talking, but they aren't listening.
Why the ending is not optional
Because the ending already announces the subject, first- and second-person pronouns are frequently dropped — Finnish is a pro-drop language, and the verb ending is what makes that possible. Puhun suomea is a complete sentence: the -n means "I," so minä is redundant. This is the opposite of English, where the pronoun does the identifying work and the verb is nearly inert.
Puhutko sinä englantia? — Puhun.
Do you speak English? — I do.
Here the reply is a single word, Puhun, and it means "I speak." No English speaker can answer "Do you speak English?" with just "Speak." The agreement ending is doing the pronoun's job. See Pro-drop for when to keep the pronoun and when to let it go.
When the verb stops agreeing
Now the crucial exceptions. In several sentence types the subject is not a plain nominative doer, and the verb parks itself in the third-person singular no matter how many things the sentence is about. These are not random irregularities — each one has a subject that is grammatically not a nominative plural, so there is simply nothing plural for the verb to agree with.
Existential and possessive sentences
An existential sentence states that something exists somewhere; its "subject" often comes in the partitive and follows the verb. The verb stays on ("is") even when many things exist.
Pöydällä on kirjoja.
There are books on the table.
Kirjoja is a partitive plural — "some books" — and yet the verb is the singular on, not ovat. Compare a normal agreeing clause, Kirjat ovat pöydällä ("The books are on the table"), where kirjat is a definite nominative plural and the verb duly turns plural. The difference is the whole engine of the existential sentence.
Kaupassa oli paljon ihmisiä.
There were a lot of people in the shop.
Numeral subjects
A subject headed by a number greater than one behaves the same way. The counted noun goes into the partitive singular, and the verb stays third-person singular.
Kaksi kissaa istuu ikkunalaudalla.
Two cats are sitting on the windowsill.
Bussissa oli kolme matkustajaa.
There were three passengers on the bus.
It feels wrong to an English speaker — "two cats sits" — but in Finnish the numeral phrase counts as a single quantity, and istuu is correct. Kaksi kissaa istuvat is a classic learner error.
The passive and the necessive
Two more construction types never agree because they have no nominative subject at all. The passive has one fixed form for every person:
Suomessa puhutaan suomea ja ruotsia.
In Finland, people speak Finnish and Swedish.
And the necessive ("must / have to") puts its logical subject in the genitive and freezes the verb as täytyy / pitää:
Meidän täytyy lähteä kohta.
We have to leave soon.
Meidän is genitive ("of us"), so there is no nominative subject to trigger agreement — täytyy stays singular whether it's I, we, or they who must go. This is explored on the Necessive Sentence page.
Common Mistakes
1. Dropping the ending because a pronoun is present. English speakers lean on the pronoun and leave the verb bare. The verb must still be inflected.
❌ Me syö lounasta.
Incorrect — syö is third-person singular; with 'me' you need syömme.
✅ Me syömme lounasta.
We're eating lunch.
2. Making the verb plural in an existential sentence. A partitive "subject" does not pluralise the verb.
❌ Pöydällä ovat kirjoja.
Incorrect — an existential with a partitive noun keeps the singular on.
✅ Pöydällä on kirjoja.
There are books on the table.
3. Agreeing with a numeral subject. Numbers above one keep the verb singular.
❌ Kaksi kissaa istuvat ikkunalla.
Incorrect — a numeral subject takes a singular verb.
✅ Kaksi kissaa istuu ikkunalla.
Two cats are sitting on the window.
4. Getting the harmony wrong on the plural ending. Front-vowel stems need -vät.
❌ He näkevat meidät.
Incorrect — näkevät has a front vowel, so it must be -vät.
✅ He näkevät meidät.
They see us.
The rule to carry away is two-sided. In an ordinary clause with a nominative subject, agreement is strict and non-negotiable — match the verb to the subject in both person and number. But the moment the subject is a partitive quantity, a number, a genitive, or nothing at all, the verb retreats to its neutral third-person-singular form. English speakers, whose verbs barely move, have to build the first habit; Finns, whose verbs always move, have to be told about the second.
