Two Finnish cases divide the labour of talking about states, and a family of verbs is attached to each. The translative -ksi marks the endpoint of a change — what something becomes, turns into, or is made to be. The essive -na/-nä marks a state or role held — what capacity someone acts in. The split is change vs stasis: are you describing an arrival at a new state, or a state that already holds? Get the verb wrong and you pick the wrong case; get the case wrong and the sentence says something you didn't mean. English blurs the two under "become," "as," and bare adjectives, so this pair is a persistent B2 stumbling block.
Translative verbs: arriving at a new state
The translative answers miksi? ("into what?") — the resulting state. Its signature verb is tulla = "to become," the everyday word for turning into a state where English would say "get," "grow," or "become."
Isoisä on tullut vanhaksi eikä enää aja autoa.
Grandpa has grown old and doesn't drive anymore.
Jos et pukeudu lämpimästi, tulet sairaaksi.
If you don't dress warmly, you'll get sick.
Alongside tulla, muuttua = "to change / turn into" describes a transformation, and ryhtyä + translative = "to become / take up (a role)":
Sää muuttui äkkiä kylmäksi, ja aloimme palella.
The weather suddenly turned cold, and we started to freeze.
Hän jätti vakituisen työn ja ryhtyi yrittäjäksi.
She left her permanent job and became an entrepreneur.
Two register notes on ryhtyä: with a translative it means "become (something)," but with an illative it means "set about (an activity)" — ryhtyä työhön "get down to work." Keep the two apart by the case.
Training into a profession: opiskella lääkäriksi
A very common flavour of "becoming" is growing into a role over time. The role you are heading toward takes the translative — with opiskella (study to become), valmistua (graduate / qualify as), kouluttautua (train as):
Poikani opiskelee lääkäriksi Turun yliopistossa.
My son is studying to become a doctor at the University of Turku.
Valmistuin insinööriksi viime keväänä.
I qualified as an engineer last spring.
Calling and considering: naming the result
A second translative group is the "naming" verbs — kutsua (call), sanoa (call / say to be), nimittää (name / appoint), valita (elect as). They assign a resulting label to someone, and that label is a translative:
Ystävät kutsuvat häntä Nipaksi, vaikka hänen nimensä on Niklas.
Friends call him Nippa, even though his name is Niklas.
Hänet valittiin puheenjohtajaksi yksimielisesti.
She was elected chair unanimously.
Essive verbs: a role held, not reached
The essive answers minä? — in what capacity, in what state. Its home verbs are toimia and työskennellä = "to work / act as," where the essive names the role you occupy while doing something. Crucially, this is a role you hold, not one you arrive at.
Työskentelen opettajana pienen kylän koulussa.
I work as a teacher at a small village school.
Hän toimii nykyään konsulttina isossa firmassa.
He now works as a consultant at a big company.
pysyä + essive = "to stay / remain (in a state)" — the state persists rather than changes:
Yritä pysyä rauhallisena, vaikka tilanne on stressaava.
Try to stay calm, even though the situation is stressful.
The tricky one: pitää jotakuta jonakin = "consider"
The verb pitää in the sense "to consider / regard as" takes an essive complement — even though the meaning ("come to regard as") sounds like a result. The person judged is partitive; the judgement is essive:
Pidän häntä luotettavana ihmisenä.
I consider her a trustworthy person.
Monet pitävät tätä elokuvaa vuoden parhaana.
Many regard this film as the best of the year.
This is a real trap because English "consider X to be Y" feels like assigning a result, which nudges learners toward the translative. In Finnish, pitää jotakuta jonakin is a held opinion — a stable state of regarding — so it takes the essive. (Note yet again how overloaded pitää is: pitää jostakin = like, pitää + infinitive = must, pitää jotakin jonakin = consider.)
The form: same stem, opposite gradation
Both endings attach to the inflectional stem, but they gradate differently — a compact contrast worth memorizing.
| Word | Essive (strong grade) | Translative (weak grade) |
|---|---|---|
| tyttö (girl) | tyttönä | tytöksi (tt → t) |
| äiti (mother) | äitinä | äidiksi (t → d) |
| sairas (sick) | sairaana | sairaaksi (-s → -aa-) |
The essive keeps the strong grade (äitinä, not äidinä); the translative gradates like the genitive to the weak grade (äidiksi). Both harmonize on the essive side (-na/-nä: opettajana, kätenä), but the translative -ksi is harmony-invariant — never -ksä (kylmäksi, not kylmäksä). And note the -s adjectives lengthen their stem: sairas → sairaaksi / sairaana, rakas → rakkaaksi / rakkaana.
Common Mistakes
❌ Työskentelen opettaja.
Incorrect — 'work as' needs the essive role marking: opettajana.
✅ Työskentelen opettajana.
I work as a teacher.
❌ Hän opiskelee lääkärinä.
Incorrect — studying to BECOME a doctor is a change: translative lääkäriksi (lääkärinä = already working as one).
✅ Hän opiskelee lääkäriksi.
She's studying to become a doctor.
❌ Sää muuttui kylmäksä.
Incorrect — the translative is harmony-invariant; there is no -ksä: kylmäksi.
✅ Sää muuttui kylmäksi.
The weather turned cold.
❌ Pidän häntä luotettavaksi.
Incorrect — pitää 'consider' takes the essive, not the translative: luotettavana.
✅ Pidän häntä luotettavana.
I consider her trustworthy.
❌ Yritän pysyä rauhalliseksi.
Incorrect — pysyä 'stay/remain' describes a state held, so essive: rauhallisena.
✅ Yritän pysyä rauhallisena.
I try to stay calm.
Key Takeaways
- Translative -ksi = the result of a change: tulla vanhaksi, muuttua kylmäksi, opiskella lääkäriksi, ryhtyä yrittäjäksi, valita puheenjohtajaksi.
- Essive -na/-nä = a role or state held: toimia / työskennellä opettajana, pysyä rauhallisena.
- The mnemonic pair: työskennellä opettajana (as, essive) vs opiskella opettajaksi (become, translative).
- pitää jotakuta jonakin = "consider" takes the essive (pidän häntä fiksuna), not the translative — it is a held opinion.
- Form: essive keeps the strong grade and harmonizes; translative gradates weak and is invariant (never -ksä); -s adjectives lengthen (sairaaksi / sairaana).

- tulla + Translative: tulla iloiseksiB1 — Finnish has no single verb 'to become' — it uses tulla plus a translative -ksi complement for change of state: tulla iloiseksi, tulla sairaaksi.
- Translative -ksi: 'becoming, into'B1 — The translative -ksi marks change into a new state — vanhaksi, opettajaksi, suomeksi. It gradates like the genitive and its vowel is invariant: never -ksä.
- Essive -na/-nä: 'as, in the role of'B1 — The essive -na/-nä marks a temporary role or state (opettajana, lapsena) and, unlike most cases, keeps the strong grade: äitinä, not äidinä.
- State vs Change: Essive vs TranslativeB1 — The essive -na/-nä marks a state you ARE in; the translative -ksi marks a state you CHANGE into — being sick vs becoming sick.
- Verb + Case: RectionB1 — Finnish verbs lexically fix the case of their complement — rakastan sinua, pidän kahvista, uskon Jumalaan — and it rarely matches the English preposition. Learn the case with the verb.
