A Finnish dictionary gives you the infinitive — puhua, juoda, tulla, haluta, tarvita, vanheta — but you can conjugate almost nothing directly from it. Every ending, every tense, every possessive attaches to the stem, and the infinitive hides the stem behind an ending you must first strip off correctly. This page is the practical skill that ties the six verb types together: given any dictionary infinitive, work out its type and produce its present stem. It is the single most useful decoding habit in Finnish verb grammar.
The decision procedure
Read the infinitive from the end and ask these questions in order. The first "yes" gives you the type.
- Does it end in -da/-dä? → Type 2. Drop -da/-dä; the stem is a long vowel or diphthong. juoda → juo-, syödä → syö-, saada → saa-.
- Does it end in a consonant + -la/-lä, -na/-nä, -ra/-rä, or in -sta/-stä? → Type 3. Drop that ending and add -e-. tulla → tule-, mennä → mene-, pestä → pese-, nousta → nouse-.
- Does it end in a vowel + -ta/-tä? Then look at the vowel right before -ta/-tä:
- Otherwise it ends in two vowels, the last one -a/-ä → Type 1. Drop the final -a/-ä. puhua → puhu-, antaa → anta-, lukea → luke-.
Then, and only then, apply consonant gradation to the stem where the person requires it.
The whole system on one page
| Type | Infinitive ends in | Stem rule | Model verb | 1st person (minä) |
|---|---|---|---|---|
| 1 | two vowels + -a/-ä (puhua) | drop the final -a/-ä | puhua | puhun |
| 2 | -da/-dä (juoda) | drop -da/-dä | juoda | juon |
| 3 | cons. + -la/-na/-ra/-sta (tulla) | drop it, add -e- | tulla | tulen |
| 4 | vowel + -ta/-tä (haluta) | drop -ta/-tä, add -a-/-ä- | haluta | haluan |
| 5 | -ita/-itä (tarvita) | replace with -itse- | tarvita | tarvitsen |
| 6 | -eta/-etä (vanheta) | replace with -ene- | vanheta | vanhenen |
Puhun vähän suomea, mutta ymmärrän aika hyvin.
I speak a little Finnish, but I understand fairly well. (Type 1: puhua → puhun)
Juon aamulla aina kaksi kuppia kahvia.
In the morning I always drink two cups of coffee. (Type 2: juoda → juon)
Tulen kotiin vasta kuuden jälkeen.
I won't get home until after six. (Type 3: tulla → tulen)
Haluan oppia lisää ennen kesää.
I want to learn more before the summer. (Type 4: haluta → haluan)
Tarvitsen kunnon loman tämän projektin jälkeen.
I need a proper vacation after this project. (Type 5: tarvita → tarvitsen)
Vanhenen, mutta en aio hidastaa vielä.
I'm getting older, but I don't intend to slow down yet. (Type 6: vanheta → vanhenen)
Why -ta/-tä is the danger zone
Three of the six types can end in -ta/-tä, so that ending alone never tells you the type — you must look one letter deeper, at the vowel or consonant in front of it:
| Ends in … | What comes before -ta/-tä | Type | Example |
|---|---|---|---|
| -sta / -stä | a consonant (s) | 3 | nousta → nousen |
| -ata, -ätä, -ota, -uta … | a, ä, o, u (not i or e) | 4 | haluta → haluan |
| -ita / -itä | i | 5 | tarvita → tarvitsen |
| -eta / -etä | e | 6 | vanheta → vanhenen |
This is why surface similarity is such a trap. Halata (to hug) and valita (to choose) rhyme, but the first is Type 4 (halaan, "I hug") and the second Type 5 (valitsen, "I choose") — the difference is entirely in that pre-ta vowel.
How this differs from English
English verbs have essentially one stem, so a dictionary form and a conjugated form share the same core: speak → I speak, choose → I choose. There is no decoding step. Finnish makes the infinitive a slightly disguised object: the ending you strip is not always the same length, and for Types 3, 5 and 6 you add material (-e-, -itse-, -ene-) that was never visible in the dictionary form. So the mental model to drop is "the infinitive is the base and I inflect it directly." The infinitive is a derived form; the stem underneath is what you actually conjugate.
When in doubt, learn the 1st-person form
Every dictionary and word list can be second-guessed, but there is one form that resolves every ambiguity at once: the first-person singular (minä). It always shows the finished stem plus a clean -n, with gradation already applied. If you know tapaan, you never again wonder whether tavata is Type 1 or Type 4; if you know pakenen, the surprise k in paeta is already handled.
Nousen yleensä kuudelta, vaikka en ole aamuihminen.
I usually get up at six, even though I'm not a morning person. (Type 3: nousta → nousen)
Valitsen mieluummin ikkunapaikan lentokoneessa.
I'd rather choose a window seat on the plane. (Type 5: valita → valitsen)
Common Mistakes
❌ Nousaan aikaisin joka aamu.
Incorrect — nousta is Type 3 (-sta), not a Type 4 -ta verb: nousen, not nousaan.
✅ Nousen aikaisin joka aamu.
I get up early every morning.
❌ Haluen kupin teetä.
Incorrect — haluta is Type 4 (add -a-, not the Type 3 -e-): haluan, not haluen.
✅ Haluan kupin teetä.
I'd like a cup of tea.
❌ Tarvin lisää aikaa.
Incorrect — tarvita is Type 5 and its stem keeps -itse-: tarvitsen, not tarvin.
✅ Tarvitsen lisää aikaa.
I need more time.
❌ Vanhean, mutta se ei haittaa.
Incorrect — vanheta is Type 6, so the stem is vanhene-: vanhenen, not vanhean.
✅ Vanhenen, mutta se ei haittaa.
I'm getting older, but it doesn't matter.
Key Takeaways
- Read the infinitive from the end: test -da/-dä (Type 2) and consonant + -la/-na/-ra/-sta (Type 3) first, then the -ta/-tä cases, then default to Type 1.
- The -ta/-tä ending covers Types 3, 4, 5 and 6 — look at the letter before it: consonant → 3, i → 5, e → 6, any other vowel → 4.
- Each type has a fixed stem move: drop -a/-ä (1), drop -da/-dä (2), add -e- (3), add -a-/-ä- (4), -itse- (5), -ene- (6). Apply gradation last.
- When a word list is unclear, the first-person singular disambiguates everything — store every verb as infinitive + minä form.
