Forming the Past: Regular Cases

Not every past tense is a puzzle. A large group of Finnish verbs takes the past marker -i- with no fuss at all: you find the stem, add -i-, and attach the endings. This page covers that clean baseline — the verbs where nothing surprising happens — so that the genuinely tricky stems (on the stem-changes and Type-2 pages) stand out clearly against it.

Two situations are regular in this sense: stems ending in u, y, o, or ö, which simply gain an -i- and form a diphthong; and stems ending in a consonant + e, where the e drops out before -i-. The endings after the marker are always the familiar six: -n, -t, -(nothing), -mme, -tte, -vat/-vät.

Stems in u, y, o, ö: just add -i-

If the stem ends in u, y, o, or ö, the -i- lands straight after it, producing a -ui-, -yi-, -oi-, or -öi- diphthong. Nothing is deleted, nothing changes quality.

Here is puhua (stem puhu-) in full:

PersonEndingPast formEnglish
minä-inpuhuinI spoke
sinä-itpuhuityou spoke
hän-ipuhuihe/she spoke
me-immepuhuimmewe spoke
te-ittepuhuitteyou (pl.) spoke
he-ivatpuhuivatthey spoke

The same treatment applies to any u/y/o/ö stem:

VerbStemPast 1sgPast 3sg
asua (live)asu-asuinasui
sanoa (say)sano-sanoinsanoi
kysyä (ask)kysy-kysyinkysyi
myöhästyä (be late)myöhästy-myöhästyinmyöhästyi

Asuin lapsena maalla, ihan metsän keskellä.

As a child I lived in the countryside, right in the middle of the forest.

Hän sanoi vain hei eikä pysähtynyt.

She just said hi and didn't stop.

Kysyin tietä, mutta kukaan ei osannut vastata.

I asked for directions, but nobody could answer.

💡
The front–back pairs behave identically: -ivat after a back stem (puhuivat, asuivat, sanoivat) and -ivät after a front stem (kysyivät, myöhästyivät). Only the harmony changes; the -i- marker is the same. See vowel harmony.

Consonant + e stems: the e drops

The other clean case is stems ending in a consonant + e, most famously the Type 3 verbs tulla (stem tule-) and mennä (stem mene-). Before -i-, the stem e simply disappears — tule- → tul- → tuli- — and then the endings attach.

Persontulla → tul-mennä → men-
minätulinmenin
sinätulitmenit
häntulimeni
metulimmemenimme
tetulittemenitte
hetulivatmenivät

The everyday verb olla ("to be") belongs here too — stem ole-, past olin, olit, oli, olimme, olitte, olivat — as does panna (stem pane-, past panin).

Tulin kotiin myöhään ja menin heti nukkumaan.

I came home late and went straight to bed.

Olimme silloin vielä nuoria emmekä pelänneet mitään.

We were young then and weren't afraid of anything.

Mihin sinä menit eilen illalla?

Where did you go last night?

The e-dropping reaches beyond Type 3. The -tse- verbs like tarvita (stem tarvitse-) also end in e, so the e drops and you get tarvitsin, tarvitsit, tarvitsi, tarvitsimme, tarvitsitte, tarvitsivat.

Tarvitsin apua muutossa, ja ystävät tulivat heti.

I needed help with the move, and my friends came right away.

The famous tuli trap

Tuli is a small word carrying a big load, so it is worth pausing on. It is:

  • the past 3sg of tulla, "(he/she/it) came";
  • the noun tuli, "fire";
  • and a close neighbour of the present tulee, "comes."

Only context tells the first two apart. Length, however, keeps tuli clearly separate from its look-alikes tuuli ("wind," long uu) and tulli ("customs," long ll) — three different words distinguished purely by which sound is held.

Hän tuli ovelle juuri, kun tuli sammui takassa.

She came to the door just as the fire went out in the fireplace.

💡
Finnish minimal pairs live and die on length. Tuli (came / fire), tuuli (wind) and tulli (customs) are three distinct words; get the short and long sounds right and there is no confusion.

What is NOT on this page

Two big groups are deliberately left for the next pages, because their stems reshape:

  • a/ä stems split unpredictably — antaa → antoi (a → o) but ostaa → osti (a drops). These are on stem changes.
  • Type-2 long-vowel stems contract — saada → sai, syödä → söi. These are on the Type-2 contraction page.

Everything on this page is safe to form by the simple recipe: add -i- (dropping a final consonant + e), then the ending.

Common Mistakes

❌ Minä puhuuin eilen suomea.

Incorrect — don't keep the present's double vowel; the past is puhuin.

✅ Puhuin eilen suomea koko päivän.

I spoke Finnish all day yesterday.

❌ Hän tulee kotiin myöhään eilen.

Incorrect — 'tulee' is present; the past of tulla is 'tuli'.

✅ Hän tuli kotiin myöhään eilen.

He came home late yesterday.

❌ Me menimme did nukkumaan aikaisin.

Incorrect — there is no 'did' auxiliary in Finnish; the past lives in the verb itself.

✅ Menimme nukkumaan aikaisin.

We went to bed early.

❌ He kysyivat saman kysymyksen kahdesti.

Incorrect — kysyä is a front-vowel verb, so the plural is -ivät: kysyivät.

✅ He kysyivät saman kysymyksen kahdesti.

They asked the same question twice.

Key Takeaways

  • u/y/o/ö stems: add -i- to make a diphthong — puhu- → puhuin, sano- → sanoin, kysy- → kysyin.
  • Consonant + e stems: the e drops — tule- → tulin, mene- → menin, ole- → olin, tarvitse- → tarvitsin.
  • The endings after -i- are the ordinary -n, -t, -(∅), -mme, -tte, -vat/-vät, harmonising as always.
  • Tuli (came), tuuli (wind), tulli (customs) differ only by length — a reminder that length is meaning in Finnish.
  • The reshaping stems (antoi, otti, sai) come next; this page is the reliable baseline.
