Nominalization and Heavy Noun Phrases

Academic and bureaucratic Finnish has a characteristic look: long, dense noun phrases where English would use a string of little clauses. Instead of "the government decided to postpone how the matter is handled, and that annoyed people", formal Finnish packs the whole thing into nouns: hallituksen päätös asian käsittelyn lykkäämisestä herätti kritiikkiä ("the government's decision to postpone the handling of the matter aroused criticism"). This is nominalization — turning verbs and clauses into noun phrases — and mastering it is what lets you read a Finnish statute or research abstract without drowning. This page shows the three engines that drive it and how the pieces stack.

Engine 1: the -minen verbal noun

Any verb can become a noun with the 4th infinitive -minen. It is completely productive — if you can conjugate the verb, you can nominalize it — and it names the act or process of doing something.

Verb-minen nounInflectional stem
uida (swim)uiminenuimise- (uimisen, uimista)
päättää (decide)päättäminenpäättämise-
käsitellä (handle)käsitteleminenkäsittelemise-
lykätä (postpone)lykkääminenlykkäämise-

Uiminen on terveellistä koko keholle.

Swimming is healthy for the whole body.

Päätöksen tekeminen vei odotettua kauemmin.

Making the decision took longer than expected.

Kielten opiskelu avartaa maailmankuvaa.

Studying languages broadens your worldview.

The verb's old arguments now become genitive modifiers in front of the noun: päätöstä tekemäänpäätöksen tekeminen ("the making of the decision").

Engine 2: -us / -uus / -os abstract nouns

Alongside the mechanical -minen, Finnish has lexicalized abstract nouns in -us, -uus, -os, -ys. These are result nouns — they name the product or outcome, not the ongoing act — and, crucially, they are not freely coinable: you learn them one by one, and each inflects on its own stem.

Act (-minen, process)Result (-us/-os, outcome)Stem
päättäminen (deciding)päätös (a decision)päätökse-
rakentaminen (building, act)rakennus (a building)rakennukse-
ratkaiseminen (solving)ratkaisu (a solution)ratkaisu-
kysyminen (asking)kysymys (a question)kysymykse-
vastaaminen (answering)vastaus (an answer)vastaukse-

Hallituksen päätös herätti laajaa kritiikkiä.

The government's decision aroused wide criticism.

Tähän kysymykseen ei ole helppoa vastausta.

There's no easy answer to this question.

💡
The process/result split is a real semantic fork. Rakentaminen is the activity of building; rakennus is the building that results. Päättäminen is deciding; päätös is the decision. When no lexicalized noun exists, -minen always works — it is the safe default for turning any verb into a noun. See abstract nouns for the full derivation patterns.

Engine 3: se, että — nominalizing a whole clause

To turn an entire clause into a noun phrase that can take any case, Finnish wraps it in se, että. The pronoun se is the grammatical noun; it inflects for whatever case the sentence needs, and the että-clause hangs off it.

Se, että olet täällä, riittää minulle.

The fact that you're here is enough for me.

Olen huolissani siitä, että et ole syönyt koko päivänä.

I'm worried about the fact that you haven't eaten all day.

En usko siihen, että hän muuttuisi.

I don't believe that he would change.

The case sits on sesiitä (elative, "about"), siihen (illative, "in") — while the content stays in the että-clause. This is the bridge between spoken and heavy written style: it keeps a finite clause but slots it into a nominal frame.

Stacking: the heavy left-branching NP

Because Finnish modifiers precede their head and link up through the genitive, nominalizations nest indefinitely without a single relative pronoun. Read the classic example from the outside in:

hallituksen päätös asian käsittelyn lykkäämisestä

LayerPieceFunction
headpäätös"decision"
gen. modifier of headhallituksen"the government's"
elative complement of päätöslykkäämisestä"about postponing"
gen. modifier of lykkääminenkäsittelyn"of the handling"
gen. modifier of käsittelyasian"of the matter"

Hallituksen päätös asian käsittelyn lykkäämisestä herätti kritiikkiä.

The government's decision to postpone the handling of the matter aroused criticism.

The same content as a spoken että-chain would run: Se, että hallitus päätti lykätä asian käsittelyä, herätti kritiikkiä. Grammatical, but conversational. The nominalized version is denser and unmistakably (academic / officialese).

Tutkimuksen tavoitteena on ilmastonmuutoksen vaikutusten arviointi metsien kasvuun.

The aim of the study is the assessment of the effects of climate change on the growth of forests.

Lain muuttumisen vuoksi verotus kiristyi vuoden alusta.

Due to the change in the law, taxation tightened from the start of the year.

The limit on nesting is readability, not grammar. Finnish will let you stack five genitive layers; a careful writer stops before the reader loses the thread. English speakers hit the opposite problem — they avoid heavy left-branching NPs entirely and keep everything as että-clauses, which reads as informal in a context that expects nominal density. For the register itself, see academic Finnish and non-finite register.

Common Mistakes

❌ Mahdollisuusen hyödyntäminen on tärkeää.

Incorrect stem — mahdollisuus inflects as mahdollisuude-: mahdollisuuden.

✅ Mahdollisuuden hyödyntäminen on tärkeää.

Making use of the opportunity is important.

❌ Hallituksen päätösen perustelut olivat heikot.

Incorrect stem — päätös inflects as päätökse-: päätöksen.

✅ Hallituksen päätöksen perustelut olivat heikot.

The reasoning behind the government's decision was weak.

❌ Asia käsittely vei liikaa aikaa.

Incorrect — the modifier must be genitive: asian käsittely.

✅ Asian käsittely vei liikaa aikaa.

The handling of the matter took too long.

❌ Olen huolissani se, että et ole syönyt.

Incorrect — huolissaan governs the elative, so the pronoun must be siitä: siitä, että.

✅ Olen huolissani siitä, että et ole syönyt.

I'm worried that you haven't eaten.

❌ Rakentaminen valmistui viime vuonna.

Wrong noun — a finished building is the result noun rakennus, not the act noun rakentaminen.

✅ Rakennus valmistui viime vuonna.

The building was completed last year.

Key Takeaways

  • -minen is the fully productive verbal noun (act/process) and inflects on -mise-: uiminen → uimisen.
  • -us / -uus / -os abstracts are lexicalized result nouns, each with its own stem: päätös → päätökse-, mahdollisuus → mahdollisuude-.
  • The act/result contrast is real: rakentaminen (building, act) vs rakennus (a building); when in doubt, -minen always works.
  • se, että nominalizes a whole clause; the case sits on se (siitä, siihen), the content on the että-clause.
  • Modifiers precede the head and stack through the genitive, so Finnish nests deeply without relative clauses — readability, not grammar, is the ceiling.
