Academic Finnish is a distinct register with three defining habits: it is precise, impersonal, and above all nominal — it prefers to talk about the reliability of the method rather than how reliable the method is. Where English can lean on an "I" that argues and shows, Finnish scholarly prose dissolves the author into the passive and packs its content into abstract nouns. This page covers the machinery: nominalization, the impersonal passive, dense clause embedding, and hedging — with the orthographic traps that trip learners up.
Nominalization I: turning verbs into things with -minen
The most productive nominalizer is -minen, which turns almost any verb into an action noun: tutkia "to research" → tutkiminen "researching, investigation", kerätä "to collect" → kerääminen "collecting". Academic prose reaches for these constantly, because a -minen noun can be the subject or object of a sentence and can carry its own genitive complement (aineiston kerääminen "the collecting of the data"). See nominalization for the full mechanics.
Aineiston kerääminen kesti kolme kuukautta.
Collecting the data took three months. (the -minen noun kerääminen is the subject; aineiston is its genitive complement — very typical of methods sections)
Ilmiön mallintaminen edellyttää tarkkoja lähtötietoja.
Modelling the phenomenon requires precise input data. (mallintaminen from mallintaa 'to model'; edellyttää 'presupposes, requires' is itself a register marker)
Nominalization II: the -uus/-yys abstracts — the backbone
If -minen turns verbs into nouns, the suffix -uus/-yys turns adjectives into abstract qualities, and this is the true backbone of the register. Speech barely uses these; academic prose stacks them: luotettava "reliable" → luotettavuus "reliability", mahdollinen "possible" → mahdollisuus "possibility", pätevä "sound, competent" → pätevyys "validity, soundness", todennäköinen → todennäköisyys "probability", toistettava → toistettavuus "repeatability". Their stems shift to -uude-/-yyde- in the cases you will use most — genitive luotettavuuden, partitive luotettavuutta.
Menetelmän luotettavuus ja tulosten yleistettävyys ovat keskeisiä käsitteitä.
The reliability of the method and the generalisability of the results are central concepts. (luotettavuus takes back-harmonic -uus, yleistettävyys front-harmonic -yys — the two allomorphs side by side)
Menetelmän luotettavuutta arvioitiin toistettavuuden avulla.
The reliability of the method was assessed by means of repeatability. (the -uude-/-yyde- stems in action: partitive luotettavuutta, genitive toistettavuuden)
The impersonal passive for objectivity
Finnish scholarly writing removes the author from view with the impersonal passive. Where English writes "I examine" or "we found", Finnish writes tarkastellaan "is examined / one examines" and todettiin "it was found". There is no agent; the finding stands on its own. This is not optional politeness — it is the default voice of the genre.
Tässä artikkelissa tarkastellaan luottamuksen ja luotettavuuden välistä suhdetta verkkokaupassa.
This article examines the relationship between trust and reliability in online commerce. (present passive tarkastellaan replaces 'I/we examine'; note the genitive chain and the stacked abstracts luottamus, luotettavuus)
Kyselyyn vastasi 312 henkilöä; vastauksia analysoitiin tilastollisesti.
312 people responded to the survey; the responses were analysed statistically. (past passive analysoitiin — the analyst is deliberately invisible)
Dense embedding: participles and että-clauses
Academic prose compresses subordinate content. Alongside ordinary että-clauses, it uses the referatiivi — a present participle in -vAn that reports "that X is/does" without a finite verb. Tutkimus osoittaa menetelmän olevan luotettava "the study shows the method to be reliable" is denser and more formal than the että-clause version.
Todettiin, että ryhmien välillä ei ollut merkitsevää eroa.
It was found that there was no significant difference between the groups. (passive todettiin plus a plain että-clause)
Tutkimus osoittaa varhaisen puuttumisen olevan ratkaisevaa.
The study shows early intervention to be decisive. (the referatiivi olevan — a -vAn participle — replaces an että-clause; note the nominalization puuttuminen and the partitive predicate ratkaisevaa)
Hedging: the caution of the register
Scholarly Finnish states claims cautiously. The key hedges are the modal saattaa "may, might", the impersonal näyttää siltä, että "it appears that" and vaikuttaa siltä, että "it seems that", and adverbs like mahdollisesti "possibly" and ilmeisesti "apparently". A results section that reads erot johtuvat X:stä ("the differences are due to X") asserts too much; erot saattavat johtua X:stä claims exactly as much as the data supports.
Erot saattavat johtua otoksen valikoitumisesta.
The differences may stem from sample self-selection. (the hedge saattavat 'may' + the nominalization valikoituminen in the elative)
Näyttää siltä, että vaikutus on väliaikainen.
It appears that the effect is temporary. (näyttää siltä, että — the standard impersonal hedge)
A worked abstract, feature by feature
Here is a single thesis-abstract sentence with its register features labelled, so you can see the machinery working together:
Tässä tutkimuksessa tarkastellaan kaksikielisyyden vaikutusta lasten kielelliseen kehitykseen, ja tulosten perusteella varhainen altistus näyttää edistävän sanaston laajuutta.
This study examines the effect of bilingualism on children's linguistic development, and on the basis of the results early exposure appears to promote breadth of vocabulary. Features: impersonal passive (tarkastellaan, no author); -yys/-us abstracts (kaksikielisyys, laajuus); -minen/-us nominalizations (kehitys, altistus); genitive chains (kaksikielisyyden vaikutusta, tulosten perusteella); and a hedge (näyttää edistävän — 'appears to promote', with the referatiivi edistävän).
Common Mistakes
❌ Minä väitän tässä työssä, että kaksikielisyys hyödyttää lapsia.
Wrong register — the overt minä 'I' is too personal for scholarly prose.
✅ Tässä työssä väitetään, että kaksikielisyys hyödyttää lapsia.
In this work it is argued that bilingualism benefits children. (impersonal passive)
❌ Menetelmän luotettavus on hyvä.
Wrong — the abstract suffix is -uus with two vowel letters; luotettavus drops one.
✅ Menetelmän luotettavuus on hyvä.
The reliability of the method is good.
❌ Argumentin pätevuus on kyseenalainen.
Harmony error — pätevä is a front-vowel word, so it takes -yys, not -uus.
✅ Argumentin pätevyys on kyseenalainen.
The soundness of the argument is questionable.
❌ Tässä luvussa tarkastellaan luottamuksen ja luotettavuuden suhde.
Wrong case — tarkastella governs the partitive object; a total-form object is ungrammatical here.
✅ Tässä luvussa tarkastellaan luottamuksen ja luotettavuuden suhdetta.
In this chapter the relationship between trust and reliability is examined. (partitive object suhdetta)
❌ Mun mielest toi menetelmä on aika epäluotettava.
Spoken register leaking into a paper — mun, mielest, toi, aika belong in chat, not scholarship.
✅ Menetelmää voidaan pitää suhteellisen epäluotettavana.
The method can be considered relatively unreliable. (impersonal, hedged, nominal)
Key Takeaways
- Academic Finnish is precise, impersonal and nominal — it names qualities and actions rather than describing them with finite verbs.
- -minen nominalizes verbs (kerääminen, mallintaminen); -uus/-yys turns adjectives into abstract qualities (luotettavuus, pätevyys) and is the register's backbone, with genitive/partitive stems in -uude-/-yyde-.
- Two suffix traps: keep the double vowel (luotettavuus, not luotettavus) and let harmony choose (-uus for back words, -yys for front — pätevyys, never pätevuus).
- Use the impersonal passive (tarkastellaan, todettiin), not an overt minä, to argue and report.
- Compress content with että-clauses and the referatiivi (-vAn: olevan, edistävän), and state claims cautiously with hedges (saattaa, näyttää siltä että).
