Finnish verbs are a central part of what makes the language feel simultaneously logical and unfamiliar to English speakers. On one hand, Finnish verb conjugation is completely regular within each verb type — there are no chaotic exceptions like English "go/went" or "be/was/were" beyond a handful of truly irregular verbs. On the other hand, the system looks very different from what English speakers are used to: person endings are attached to the verb stem, there is negative verb that conjugates separately, and there are six verb types with slightly different stem formations. This guide walks through the whole system clearly, starting from the basics.
How Finnish Verbs Work
In Finnish, personal endings are added to the verb stem to show who is performing the action. Unlike English, where "I run", "you run", "she runs" and only the third person singular changes, Finnish has a distinct ending for all six persons.
Also unlike English (and many European languages), Finnish verbs in the negative are formed using a separate negative auxiliary verb (ei in its various forms) combined with the connective form of the main verb. This is one of the most distinctive features of Finnish verb grammar.
The Six Personal Endings
Finnish has six grammatical persons. Here are the standard subject pronouns:
- 1st singular — minä (or mä in speech), I
- 2nd singular — sinä (or sä in speech), you
- 3rd singular — hän, he/she (Finnish has no gender distinction)
- 1st plural — me, we
- 2nd plural — te, you (plural)
- 3rd plural — he, they
Note: in spoken Finnish, pronouns are often contracted (mä, sä, se, me, te, ne), and the pronouns are more frequently dropped than in formal writing. Still, learners should start with the full forms.
The Six Verb Types
Finnish verbs are divided into six types based on their infinitive ending. Knowing the type tells you how to form the stem and apply the endings. The infinitive (dictionary form) ends in -a or -ä (front vowel harmony variant).
Type 1 Verbs: Infinitive ends in two vowels + -a/-ä
These are the most common. The infinitive ends in a vowel + a/ä.
Examples: puhua (to speak), lukea (to read), kirjoittaa (to write), sanoa (to say)
Stem: Remove the final -a/-ä
- puhua → puhu-
- lukea → luke-
- kirjoittaa → kirjoitta-
Present tense endings:
- minä — -n, puhun, luen
- sinä — -t, puhut, luet
- hän — stem vowel doubled, puhuu, lukee
- me — -mme, puhumme, luemme
- te — -tte, puhutte, luette
- he — -vat/-vät, puhuvat, lukevat
Note the third-person singular: the final vowel of the stem is doubled (lengthened), with no -n or -t ending.
Type 2 Verbs: Infinitive ends in -da/-dä
Examples: syödä (to eat), juoda (to drink), saada (to get/receive), myydä (to sell)
Stem: Remove the -da/-dä → the stem often ends in a long vowel or diphthong
- syödä → syö-
- juoda → juo-
- saada → saa-
Present tense: syödä (to eat)
- minä — syön
- sinä — syöt
- hän — syö
- me — syömme
- te — syötte
- he — syövät
The third-person singular is just the bare stem (already a long vowel — no doubling needed because it's already long).
Type 3 Verbs: Infinitive ends in -la/-lä, -ra/-rä, -na/-nä, -sta/-stä
Examples: tulla (to come), mennä (to go), purra (to bite), nousta (to rise)
Stem: Remove the infinitive ending, leaving a consonant cluster stem
- tulla → tul-
- mennä → men-
But for the present tense, a connecting vowel -e- is inserted:
- tulla → tule-
- mennä → mene-
Present tense: tulla (to come)
- minä — tulen
- sinä — tulet
- hän — tulee
- me — tulemme
- te — tulette
- he — tulevat
Type 4 Verbs: Infinitive ends in -ata/-ätä, -ota/-ötä, -uta/-ytä
Examples: tavata (to meet), haluta (to want), pelata (to play a game), parata (to recover)
Stem: Replace the infinitive ending with -aa-/-ää- in conjugated forms — actually, the stem ends in the vowel before the -ta, doubled:
- tavata → tapaa- (note consonant gradation: t→p)
- haluta → halua-
- pelata → pelaa-
Present tense: haluta (to want)
- minä — haluan
- sinä — haluat
- hän — haluaa
- me — haluamme
- te — haluatte
- he — haluavat
Type 5 Verbs: Infinitive ends in -ita/-itä
Examples: tarvita (to need), merkitä (to mean/mark), häiritä (to disturb)
Stem: Replace -ita/-itä with -itse-
- tarvita → tarvitse-
- merkitä → merkitse-
Present tense: tarvita (to need)
- minä — tarvitsen
- sinä — tarvitset
- hän — tarvitsee
- me — tarvitsemme
- te — tarvitsette
- he — tarvitsevat
Type 6 Verbs: Infinitive ends in -eta/-etä
Examples: paeta (to flee), kylmetä (to get cold), vanheta (to grow old)
Stem: Replace -eta/-etä with -ene-
- vanheta → vanhene-
- kylmetä → kylmene-
These are relatively uncommon and follow the same personal endings as other types.
Consonant Gradation
Finnish has a feature called consonant gradation (astevaihtelu), where certain consonants alternate between "strong" and "weak" grades depending on the syllable structure. This affects many verbs when you form stems.
The most common gradation pairs:
- pp — p, tappaa → tapan
- tt — t, ottaa → otan
- kk — k, nukkua → nukun
- p — v, tavata → tapaan
- t — d, pitää → pidän
- k — (disappears), lukea → luen
- mp — mm, ampua → ammun
- lt — ll, tulla (stem tul-)
The rule is: if adding the personal ending closes the syllable (makes it end in a consonant), the consonant weakens. If the syllable opens (ends in a vowel), the strong grade is used.
This sounds complex in description but becomes intuitive with practice. Learners should learn each verb with its stem form from a dictionary.
The Negative Verb
One of the most distinctive features of Finnish is the negative verb — a separate verb that conjugates by person and carries the negation, while the main verb appears in a special connective form (sometimes called the stem or the "negative stem").
The negative verb ei:
- minä — en
- sinä — et
- hän — ei
- me — emme
- te — ette
- he — eivät
The connective form of the main verb is formed by taking the stem (the form without the -n ending of the first-person singular):
- puhua → minä puhun → connective: puhu
- lukea → minä luen → connective: lue
- tulla → minä tulen → connective: tule
Negative present:
- minä — en puhu
- sinä — et puhu
- hän — ei puhu
- me — emme puhu
- te — ette puhu
- he — eivät puhu
This is completely regular once you know the connective form. All six negative forms use the same connective — only the negative verb changes.
Past Tense
The past tense in Finnish is formed with the -i- suffix inserted between the stem and the personal ending.
For Type 1 verbs, the stem vowel changes or shortens when -i- is added:
puhua (to speak):
- minä puhuin (I spoke)
- sinä puhuit
- hän puhui
- me puhuimme
- te puhuitte
- he puhuivat
lukea (to read):
- minä luin (I read)
- sinä luit
- hän luki
- me luimme
- te luitte
- he lukivat
The past tense of the negative uses the past participle form of the main verb + the negative auxiliary:
- en puhunut — I did not speak
- et puhunut
- ei puhunut
- emme puhuneet
- ette puhuneet
- eivät puhuneet
The past participle is formed with -nut/-nyt (singular) or -neet/-neet (plural).
The Perfect and Pluperfect
Finnish has a perfect tense (describing past actions with present relevance) and a pluperfect (past before another past action), formed with olla (to be) + past participle.
Perfect:
- minä olen puhunut — I have spoken
- hän on lukenut — he/she has read
- me olemme tulleet — we have come
Pluperfect:
- minä olin puhunut — I had spoken
- hän oli lukenut — he/she had read
The Conditional Mood
The conditional (equivalent to "would") is formed with the suffix -isi- + personal endings:
puhua conditional:
- minä puhuisin — I would speak
- sinä puhuisit
- hän puhuisi
- me puhuisimme
- te puhuisitte
- he puhuisivat
Negative conditional:
- en puhuisi — I would not speak
The Imperative
Singular imperative (command to one person): bare stem
- Puhu! — Speak!
- Tule! — Come!
- Lue! — Read!
Plural imperative: stem + -kaa/-kää
- Puhukaa! — Speak! (to a group)
- Tulkaa! — Come! (to a group)
Infinitive Forms
Finnish has several infinitive forms beyond the basic puhua-type:
- 1st infinitive (puhua): the dictionary form
- 2nd infinitive (stem + -e- + case): used in various grammatical structures
- 3rd infinitive (stem + -ma/-mä- + case): indicates manner or location of an action
- olen syömässä — I am (in the act of) eating
- menen syömään — I'm going to eat (lit. going into eating)
These advanced infinitive forms are a rich part of Finnish grammar that repay study once you're comfortable with the basic conjugation.
Truly Irregular Verbs
Finnish has very few truly irregular verbs. The most important are:
olla (to be):
- minä — olen, olin
- sinä — olet, olit
- hän — on, oli
- me — olemme, olimme
- te — olette, olitte
- he — ovat, olivat
Negative: en ole, et ole, ei ole, etc.
käydä (to visit/go to) and a few others have minor irregularities but are learnable as individual items.
Summary
- Verb types — 6 types based on infinitive ending
- Personal endings — -n, -t, doubled vowel, -mme, -tte, -vat/-vät
- Negative — Conjugated negative verb (en/et/ei...) + connective form
- Past tense — -i- infix + personal endings
- Conditional — -isi- + personal endings
- Singular imperative — Bare stem
- Consonant gradation — Consonants alternate between strong and weak grades
Finnish verb conjugation rewards methodical learning. Start with Type 1 verbs in the present tense, add negatives, then move to past tense, and build from there. The system is more regular than it first appears, and each new pattern you learn applies consistently across hundreds of verbs. Onnea opiskeluun!
