Olla is the most frequent verb in Finnish, and it earns that place by doing several jobs that English splits across different words. It is the copula "to be," it states that something exists, it expresses possession where English uses "have," it builds the perfect tense, and it describes states and feelings. Learning its handful of forms and its main patterns unlocks an enormous slice of everyday Finnish. This page surveys all the jobs and points you to the dedicated pages for each.
First, the forms
You will use these constantly, so front-load them. The two you cannot live without are the third-person forms — singular on and plural ovat — which appear in nearly every pattern below.
| Person | Present (affirmative) | Present (negative) |
|---|---|---|
| minä (I) | olen | en ole |
| sinä (you sg.) | olet | et ole |
| hän / se (he/she/it) | on | ei ole |
| me (we) | olemme | emme ole |
| te (you pl.) | olette | ette ole |
| he / ne (they) | ovat | eivät ole |
The past (imperfect) is olin, olit, oli, olimme, olitte, olivat; the past participle used in the perfect is ollut (singular) / olleet (plural). Full paradigms are on the olla verb reference.
1. Copula: "X is Y"
The plain "A is B" sentence. The predicate — a noun or adjective — follows olla, and here is the first thing English speakers must unlearn: Finnish has no articles. There is no "a" or "the" to insert after "is."
Hän on opettaja.
She is a teacher.
Tämä kahvi on todella hyvää.
This coffee is really good.
Notice hyvää in that second example: when the subject is a mass noun (coffee, water, an uncountable), the predicate adjective takes the partitive (hyvää, not hyvä). For ordinary countable subjects it stays plain: Talo on iso ("The house is big"). That distinction deepens later; at A1, just remember mass nouns pull the predicate into the partitive.
2. Existence: "there is / there are"
To say something exists somewhere, Finnish uses olla with the place first and the thing that exists last — and the verb stays in the singular on even for plural things. This is the existential sentence, and its word order (place – on – thing) is the reverse of the English "there is."
Pöydällä on kirja.
There is a book on the table.
Kaupungissa on vanha museo ja kaksi kirkkoa.
There is an old museum and two churches in the town.
Under negation, the existing thing goes into the partitive: Pöydällä ei ole kirjaa ("There is no book on the table"). The full behaviour — including why the subject can be partitive — is on the existential sentences page.
3. Possession: minulla on replaces "have"
This is the pattern English speakers most want to get wrong, because they hunt for a verb "to have." Finnish has no such verb. Instead it says, literally, "at me is X" — the owner goes in the adessive (-lla/-llä), and olla stays as on.
Minulla on auto.
I have a car. (lit. at-me is a car)
Onko sinulla sisaruksia?
Do you have any siblings?
Meillä on tänään vieraita.
We have guests today.
The owner is minulla, sinulla, hänellä, meillä, teillä, heillä — the adessive of the pronouns. Under negation the possessed thing turns partitive: Minulla ei ole autoa ("I don't have a car"). This construction is important enough to have its own page: possession with adessive + olla.
4. Location: "X is at a place"
Flip the existential around and olla simply tells you where a known thing is. Now the thing comes first and the place last — ordinary subject–verb–place order.
Kirja on pöydällä.
The book is on the table.
Lapset ovat jo koulussa.
The children are already at school.
Here the plural subject does take plural agreement (lapset ovat), unlike the existential's fixed on — a useful contrast between the two sentence types, laid out on the three olla-sentence types page.
5. Perfect tense: olen puhunut
Olla is the auxiliary of the perfect and pluperfect — Finnish's "have done" tenses. Combine a present or past form of olla with the past participle (the -nut/-nyt form):
Olen jo puhunut hänen kanssaan asiasta.
I have already spoken with her about the matter.
Oletko koskaan käynyt Lapissa?
Have you ever been to Lapland?
Note that English uses "have" for this tense but Finnish uses olla ("be"): olen puhunut is literally "I am spoken." The participle agrees in number — olen puhunut (I have) but he ovat puhuneet (they have).
6. States and feelings: olen väsynyt
Finally, olla carries states of body and mind — tired, happy, in a hurry — as a straightforward copula with an adjective or participle.
Olen tosi väsynyt, menen nukkumaan aikaisin.
I'm really tired, I'm going to bed early.
Oletko valmis? Bussi lähtee kohta.
Are you ready? The bus leaves soon.
Age uses this too — Olen kolmekymmentävuotias ("I'm thirty years old") — while hunger and cold, as the tip noted, prefer the possessive frame minulla on nälkä / kylmä. Fixed olla expressions are gathered on the olla idioms page.
Common Mistakes
❌ Minä haven auto.
Incorrect — Finnish has no verb 'have'; possession is minulla on: Minulla on auto.
✅ Minulla on auto.
I have a car.
❌ Hän on yksi opettaja.
Incorrect — no article after the copula; 'a' is not translated: Hän on opettaja.
✅ Hän on opettaja.
She is a teacher.
❌ Pöydällä ovat kirjat.
Incorrect — the existential verb stays singular on even with a plural thing: Pöydällä on kirjoja.
✅ Pöydällä on kirjoja.
There are books on the table.
❌ Minulla ei ole auto.
Incorrect — under negation the possessed thing turns partitive: autoa.
✅ Minulla ei ole autoa.
I don't have a car.
❌ Olen puhui hänen kanssaan.
Incorrect — the perfect is olla + past participle, not olla + a finite past: Olen puhunut.
✅ Olen puhunut hänen kanssaan.
I have spoken with her.
Key Takeaways
- Learn the two workhorses first: singular on, plural ovat — they appear in almost every pattern.
- Copula: Hän on opettaja — no article; mass-noun predicates go partitive (kahvi on hyvää).
- Existence: place – on – thing, verb stays singular (Pöydällä on kirja).
- Possession: no "have" verb — minulla on auto, adessive owner + on; negation turns the thing partitive (ei ole autoa).
- Perfect: olla
- past participle (olen puhunut) — Finnish "be," not "have."
- States: olen väsynyt, olen valmis; hunger/cold use the possessive frame minulla on nälkä.
