The nominative is the form you meet first: the one printed in the dictionary, written on the flashcard, listed in the vocabulary. Talo, kylä, käsi, nainen — in the singular it has no ending at all. That bareness makes it feel like the "default," and mostly it is. But "no ending" hides two things worth knowing early: the nominative is not always the same as the inflectional stem, and it does more jobs than just marking the subject. Getting both straight now saves a great deal of confusion later.
The subject
The core job of the nominative is to mark the subject — the doer or the thing the sentence is about.
Talo on iso ja valoisa.
The house is big and bright.
Naapuri soitti eilen ja kysyi kuulumisia.
The neighbor called yesterday and asked how things are going.
Auto ei käynnisty tässä pakkasessa.
The car won't start in this cold.
Whenever a noun is the one performing or undergoing the action as the grammatical subject, it stands in the nominative — singular with no ending, plural with -t.
The predicate noun (after olla)
When you equate two things with olla ("to be"), the noun on the other side of the equals sign is also nominative. English does the same ("She is a teacher"), so this one is intuitive.
Hän on opettaja isossa lukiossa.
She/He is a teacher at a big high school.
Isäni on insinööri ja äitini on lääkäri.
My father is an engineer and my mother is a doctor.
Helsinki on Suomen pääkaupunki.
Helsinki is Finland's capital.
(Some predicates take the partitive instead — with masses or open-ended qualities, maito on hyvää, "milk is good." But for a plain "X is a Y" equation, the predicate noun is nominative.)
The surprising one: nominative as a total object
Here is the part textbooks introduce too quietly. Normally a whole, definite object takes the accusative, which for most words is shaped like the genitive: ostan auton ("I buy the car"). But in three specific constructions the singular total object appears in the nominative instead:
| Construction | Example | Object form |
|---|---|---|
| Imperative | Osta auto! — Buy a/the car! | auto (nominative) |
| Necessive (must/have to) | Minun täytyy ostaa auto. — I have to buy a car. | auto (nominative) |
| Passive | Auto ostettiin eilen. — The car was bought yesterday. | auto (nominative) |
Why? These constructions have no ordinary nominative subject — an imperative addresses "you" without naming it, the necessive puts the person in the genitive (minun), and the passive names no doer at all. With the nominative "subject slot" standing empty, the total object steps into it. This is a genuinely tricky corner of Finnish, and it trips up learners for months — so it is worth flagging honestly rather than smoothing over. The full account is on the accusative page.
Sulje ovi, ole hyvä — ulkona on kylmä.
Close the door, please — it's cold outside.
Meidän pitää maksaa lasku tänään.
We have to pay the bill today.
Talo myytiin viime viikolla kolmessa päivässä.
The house was sold last week in three days.
The nominative plural: -t
The basic (nominative) plural adds -t to the plural stem. For many words that stem is the weak grade, so gradation shows up alongside the ending:
| Singular | Nominative plural | Note |
|---|---|---|
| talo (house) | talot | plain -t |
| kissa (cat) | kissat | plain -t |
| kirja (book) | kirjat | plain -t |
| käsi (hand) | kädet | stem käde-, t→d |
| nainen (woman) | naiset | stem naise- |
This -t plural marks the subject and the total object in the plural. It is not the "some / indefinite" plural — that is the partitive plural (formed with -j-/-i-, e.g. taloja, "some houses"), which comes later. For now, hold onto the contrast: talot = the houses / all the houses (nominative), versus taloja = some houses (partitive).
Kaupat ovat kiinni sunnuntaisin.
The shops are closed on Sundays.
Lapset menivät jo nukkumaan.
The children already went to sleep.
Kädet olivat aivan kylmät kävelyn jälkeen.
My hands were completely cold after the walk.
The nominative is not the stem
This is the single most important warning on the page, and the reason the whole chapter is built around stems rather than the dictionary form. The nominative frequently is not the base you add endings to.
- käsi looks like it should give *käsin, but the stem is käde-/kät-: genitive käden, partitive kättä, inessive kädessä.
- nainen has the stem naise-: genitive naisen, plural naiset.
- The nominative can even hide the gradation direction. Opas ("guide") shows the weak grade in the nominative (single p), but its stem is strong: genitive oppaan, ablative oppaalta.
Käsi on kipeä, mutta käden liikuttaminen auttaa.
My hand hurts, but moving the hand helps.
Opas kertoi kaupungin historiasta, ja kysyin oppaalta lisää.
The guide talked about the city's history, and I asked the guide for more.
So never assume "nominative + ending." First find the stem — the whole two-stem story is on the stem concept page — and only then attach the case endings.
Common Mistakes
❌ Ostan auto huomenna.
Incorrect — an ordinary total object is not the nominative; it takes the accusative/genitive form auton.
✅ Ostan auton huomenna.
I'm buying a/the car tomorrow.
❌ Osta auton!
Incorrect — after an imperative the singular total object IS the nominative: auto.
✅ Osta auto!
Buy a/the car!
❌ Minun täytyy ostaa auton.
Incorrect — the necessive total object is nominative: auto.
✅ Minun täytyy ostaa auto.
I have to buy a car.
❌ Käsit olivat kylmät.
Incorrect — the plural of käsi is kädet (stem käde- + t, t→d), not käsit.
✅ Kädet olivat kylmät.
My hands were cold.
❌ Hän on opettajaa.
Incorrect — a plain predicate noun after olla is nominative, not partitive: opettaja.
✅ Hän on opettaja.
She/He is a teacher.
Key Takeaways
- The nominative is the bare dictionary form — no ending in the singular, -t in the plural.
- It marks the subject and the predicate noun after olla (Hän on opettaja).
- It is also the total object after an imperative, necessive, or passive (Osta auto!, minun täytyy ostaa auto, auto ostettiin) — a genuinely tricky corner.
- The plural -t is the subject/total-object plural (talot), not the "some" plural — that is the partitive (taloja), covered later.
- The nominative is often not the stem (käsi → käde-, opas → oppaa-); always find the stem before adding endings.

- Two Stems: Dictionary Form vs Inflectional StemA1 — Finnish case endings attach to an inflectional stem, not to the dictionary form — and the genitive reliably reveals that stem (talon→talo-, käden→käde-).
- Nominative: Subject and Basic PredicateA1 — The endingless nominative marks the subject and the predicate noun after olla — and, surprisingly, the total object after imperatives, passives and necessives.
- The Plural Marker -t (Nominative)A1 — The nominative plural adds -t to the stem (talo→talot, käsi→kädet). It marks plural subjects and total objects — and no other case uses it.
- The Accusative: A Case Without Its Own EndingA2 — Finnish marks the total object with a borrowed ending — genitive -n, nominative, or -t; only pronouns keep a true accusative (minut, sinut, hänet).
- Finnish Nouns: No Gender, No ArticlesA1 — The big picture: Finnish nouns have no gender and no articles; one word inflects for around fifteen cases and two numbers by adding suffixes to a stem.
