How Finnish Verbs Work | Finnish Grammar

The Finnish verb is the engine room of the language, and it works on very different principles from the English verb. There is no do, no will, no -ing, and no separate word for "I," "you" or "we" in most sentences — all of that is folded into the verb's endings. This page is the map for the whole Verbs section: it shows the moving parts — agreement, verb types, tenses, moods, negation, the passive and the non-finite forms — and points you to the page that treats each one in depth. Read it first to see how the pieces fit, then follow the links.

A verb carries its subject

A Finnish verb changes its ending to match the person doing the action. Because the ending already says who, the subject pronoun is usually dropped — puhun on its own means "I speak." Here is the whole present-tense set of puhua ("to speak"):

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 vähän suomea, mutta ymmärrän paljon enemmän.

I speak a little Finnish, but I understand much more.

Puhummeko me jo liian nopeasti?

Are we already speaking too fast?

The endings -n, -t, -(vowel), -mme, -tte, -vat/-vät are the same for every verb in the present tense — learn them once. The pronoun comes back only for emphasis or contrast (minä maksan, sinä et — "I'll pay, you won't"). The full story of these endings, including the third person, is on the personal endings page.

💡

Because the ending marks the person, dropping the pronoun is the normal, unmarked choice — puhun suomea, not minä puhun suomea, in ordinary speech. Keeping minä in every sentence sounds heavy and slightly foreign. The third person (hän puhuu) and plurals are the exception where the pronoun is often kept.

No "do," no "-ing": what Finnish lacks

Three English habits have no equivalent in Finnish, and un-learning them is half the battle:

No do / does auxiliary. Questions are made by adding the clitic -ko / -kö to the verb, and negation uses a special negative verb (below) — never a helper "do."
No progressive -ing. Puhun covers both "I speak" and "I am speaking"; the simple present does both jobs.
No future tense. The present tense also expresses the future; time is shown by an adverb (huomenna "tomorrow") if needed.

Puhutko sinä englantia?

Do you speak English? / Are you speaking English?

Soitan sinulle huomenna.

I'll call you tomorrow.

That first example is the pattern to internalize: puhut + -ko = the question, with no "do" anywhere. The second shows the present soitan carrying a future meaning.

Six verb types fix the stem

Every Finnish verb belongs to one of six types, sorted by the shape of its dictionary form (the first infinitive). The type tells you how to strip the infinitive down to the stem that the personal endings attach to. This is the single most important thing to learn about a new verb.

Type	Infinitive ends in	Example	Present stem	"I" form
1	two vowels	puhua	puhu-	puhun
2	-da / -dä	syödä	syö-	syön
3	-la, -na, -ra, -sta	tulla	tule-	tulen
4	-ata / -ätä (etc.)	haluta	halua-	haluan
5	-ita / -itä	tarvita	tarvitse-	tarvitsen
6	-eta / -etä	vanheta	vanhene-	vanhenen

Tulen kotiin kuudelta ja syön heti.

I'll come home at six and eat right away.

Tarvitsen apuasi, koska en osaa tätä yksin.

I need your help, because I can't do this on my own.

Notice how different the stem can look from the infinitive — tarvita becomes tarvitse-, tulla becomes tule-. The overview of the six types is on verb types, and the method for extracting the stem of any verb is on finding the stem.

Tenses: present, past, and two compound tenses

Finnish has only two simple tenses and two compound tenses (built with the helper verb olla, "to be"):

Present (puhun) — also does the future. See present tense.
Past / imperfect (puhuin, "I spoke") — the plain narrative past. See past tense.
Perfect (olen puhunut, "I have spoken") — olla
- past participle. See perfect.
Pluperfect (olin puhunut, "I had spoken"). See pluperfect.

Puhuin hänen kanssaan eilen, mutta emme sopineet mitään.

I spoke with him/her yesterday, but we didn't agree on anything.

Olen jo puhunut pomolle asiasta.

I've already spoken to the boss about it.

Moods: indicative, conditional, imperative, potential

The mood shows how the speaker frames the action — as fact, as a hypothetical, as a command, or as a guess:

Indicative — plain statements and questions (puhun). The default, everything above.
Conditional (puhuisin, "I would speak") — the -isi- marker; hypotheticals and polite requests. See conditional.
Imperative (puhu! "speak!") — commands. See imperative.
Potential (puhunen, "I may well speak") — the -ne- marker; a (formal / literary) "probably." Rare in speech. See potential.

Puhuisin mielelläni, jos minulla olisi enemmän aikaa.

I'd gladly talk if I had more time.

Negation is a verb of its own

Here is the most un-English thing of all: Finnish negates with a separate conjugating verb, en, et, ei, emme, ette, eivät — literally "I-not, you-not, he-not…" — followed by a bare connegative stem of the main verb. There is no "not" particle and no "don't."

Person	Negative	Meaning
minä	en puhu	I don't speak
sinä	et puhu	you don't speak
hän	ei puhu	he/she doesn't speak
me	emme puhu	we don't speak

En puhu ranskaa lainkaan.

I don't speak French at all.

The negative verb takes the personal ending (en, et, ei…) and the main verb drops to a bare stem (puhu). In the past it becomes en puhunut ("I didn't speak"), using the past participle. This whole system is on the negative verb page.

The passive: an actor-less verb

Finnish has one passive (better called the impersonal), a single form meaning "one / people / someone" does the action, with no named subject: puhutaan = "one speaks / it is spoken." In colloquial Finnish it also doubles as the "we" form (me puhutaan = "we speak").

Suomessa puhutaan suomea ja ruotsia.

In Finland, Finnish and Swedish are spoken.

Its full paradigm across tenses and moods is on the passive page.

Non-finite forms: infinitives and participles

Beyond the conjugated (finite) forms, Finnish verbs have a rich set of non-finite forms that behave like nouns and adjectives — several infinitives (puhua, puhuen, puhumassa…) and four participles (puhuva "speaking," puhunut "having spoken," puhuttava, puhuttu). These build everything from purpose clauses to relative-clause equivalents. Start with the infinitives and participles overviews.

💡

Finnish verbs have no gender and no articles to worry about, and only two simple tenses. The complexity lives elsewhere — in the six stem types, the case the object takes, and the non-finite forms. Budget your effort accordingly: master the stem types early, and the rest of the system clicks into place.

Common Mistakes

❌ Sinä teet puhut suomea?

Incorrect — there's no 'do' auxiliary; a question adds -ko/-kö to the verb: Puhutko suomea?

✅ Puhutko suomea?

Do you speak Finnish?

❌ Minä olen puhumassa nyt.

Overloaded — there's no 'am …-ing' progressive; the plain present already means it: Puhun nyt.

✅ Puhun nyt puhelimessa.

I'm speaking on the phone right now.

❌ Minä ei puhu englantia.

Incorrect — the negative verb agrees with the person: en for 'I'. It's en puhu, not ei puhu.

✅ En puhu englantia.

I don't speak English.

❌ Minä puhun huomenna hänelle.

Unnatural — drop the redundant minä; the ending already marks 'I': Puhun hänelle huomenna.

✅ Puhun hänelle huomenna.

I'll talk to him/her tomorrow.

Key Takeaways

A verb's ending marks the person (puhun, puhut, puhuu…), so the subject pronoun is normally dropped.
There is no do, no -ing progressive, and no future tense — the present covers the future.
Every verb belongs to one of six types that fix its stem; questions add -ko/-kö.
Tenses: present, past, and the olla-built perfect and pluperfect. Moods: indicative, conditional, imperative, and the rare potential.
Negation is a separate conjugating verb (en, et, ei…) plus a bare stem; the passive (puhutaan) is subjectless; non-finite forms (infinitives, participles) do the heavy lifting in complex sentences.
