Finnish has no prepositions to speak of. Where English says in the house, from the house, to the house, on the table, for my friend, Finnish changes the end of the noun. Those changes are the cases. Fifteen exist; eight do the daily work.
The three forms to memorise
For every noun, learn the nominative, the genitive and the partitive. Everything else is built from them.
| talo (house) | kauppa (shop) | kieli (language) | lapsi (child) | |
|---|---|---|---|---|
| nominative | talo | kauppa | kieli | lapsi |
| genitive | talon | kaupan | kielen | lapsen |
| partitive | taloa | kauppaa | kieltä | lasta |
The genitive gives you the weak stem (talo-, kaupa-, kiele-, lapse-) that most cases attach to. Our noun pages show all three at the top and the full table below.
The grammatical cases
| Case | Question | Ending | Meaning | Example |
|---|---|---|---|---|
| Nominative | mikä? kuka? | – | subject, dictionary form | Talo on iso. |
| Genitive | minkä? kenen? | -n | owner, "of" | lapsen kirja, Suomen pääkaupunki |
| Partitive | mitä? ketä? | -a/-ä, -ta/-tä, -tta/-ttä | part of something, ongoing action, after numbers and negatives | juon kahvia, kolme lasta, ei ole aikaa |
| Accusative | -n or – | complete object | Ostin kirjan. Syön leivän. |
The partitive is the case that decides whether a Finn understands you as "I read the book" (luin kirjan, finished) or "I was reading the book" (luin kirjaa, unfinished). Learners overuse the nominative; when unsure with objects, the partitive is the safer error.
The six locative cases
Three for inside (containers, cities, buildings), three for on/at (surfaces, streets, people, events):
| "in / inside" (-s-) | "on / at" (-l-) | |
|---|---|---|
| where? (missä? millä?) | inessive -ssa/-ssä: talossa, Helsingissä, koulussa | adessive -lla/-llä: pöydällä, kadulla, Tampereella, minulla |
| from where? (mistä? miltä?) | elative -sta/-stä: talosta, Suomesta, kaupasta | ablative -lta/-ltä: pöydältä, kadulta, ystävältä |
| to where? (mihin? mille?) | illative -Vn / -hVn / -seen: taloon, Suomeen, maahan, huoneeseen | allative -lle: pöydälle, kadulle, ystävälle, minulle |
Useful facts:
- Having uses the adessive: Minulla on kissa (I have a cat, literally "on me is a cat").
- Giving to someone uses the allative: Annan avaimen sinulle.
- Cities are usually inessive (Helsingissä), but some take the adessive by tradition: Tampereella, Vantaalla, Rovaniemellä, Venäjällä. Every city guide tells you which.
- The illative has three endings. Doubled vowel + n for stems ending in one vowel (taloon, kaupunkiin), -hVn for one-syllable words ending in two vowels (maahan, työhön, tiehen), -seen for longer words ending in a long vowel (huoneeseen, Espooseen).
The remaining cases
| Case | Ending | Meaning | Example |
|---|---|---|---|
| Essive | -na/-nä | as something; on a day | opettajana (as a teacher), maanantaina (on Monday), jouluna |
| Translative | -ksi | becoming something; for a time | Minusta tulee lääkäriksi. Muutin Suomeen vuodeksi. |
| Abessive | -tta/-ttä | without | rahatta (without money), usually ilman rahaa instead |
| Comitative | -ine- + possessive | together with | vaimoineen (with his wife), formal |
| Instructive | -in | by means of | omin silmin (with one's own eyes), fixed phrases |
The last three you can recognise and ignore. Finns use ilman + partitive for "without" in speech.
Plural
Every case has a plural, built with -i- (or -j- between vowels): taloissa (in the houses), taloista, taloihin, taloilla, taloille, taloina, taloiksi. The plural nominative is -t: talot, kaupat, lapset. The plural partitive and genitive are the trickiest forms in the language (taloja, talojen; lapsia, lasten), which is why every noun page gives them explicitly.
