Formal Croatian — the Croatian of law, administration, journalism, and academic prose — runs on nominalization: the habit of recasting whole clauses as noun phrases. Where casual speech says nakon što je došao "after he arrived", a written report says nakon dolaska "after the arrival"; where you would say važno je da čitamo "it's important that we read", a textbook prefers važnost čitanja "the importance of reading". The two engines are the verbal noun in -nje (čitanje "reading") and the abstract noun in -ost (mogućnost "possibility"). The effect is denser, more impersonal, more formal text. This page is about using nominalization as a register and condensation strategy; the morphology of how each noun is built lives on verbal nouns (-nje), abstract nouns (-ost), and noun-forming suffixes.
The verbal noun and its genitive object
The verbal noun in -nje turns an action into a thing: čitati "to read" → čitanje "(the) reading". The catch that trips every English speaker is what happens to the verb's object. A finite verb takes its object in the accusative — čitam knjigu "I read the book". But the verbal noun is a noun, and a noun cannot govern an accusative object; instead the former object goes into the genitive, exactly as English uses "of": čitanje knjige "the reading of the book".
| Clause (finite) | Nominalized phrase | English |
|---|---|---|
| čitam knjigu (acc.) | čitanje knjige (gen.) | "the reading of the book" |
| gradili su most (acc.) | gradnja mosta (gen.) | "the building of the bridge" |
| rješavamo problem (acc.) | rješavanje problema (gen.) | "the solving of the problem" |
Čitanje knjige oduzelo mi je cijeli vikend.
Reading the book took me the whole weekend. — verbal noun 'čitanje' with its object in the genitive, 'knjige'.
Izgradnja nove škole počinje na jesen.
Construction of the new school begins in the autumn. — 'izgradnja' + genitive 'nove škole'; the headline-and-report register.
Abstract -ost nouns: turning a quality into a noun
Where -nje nominalizes an action, -ost nominalizes a quality — it builds an abstract noun from an adjective. Moguć "possible" → mogućnost "possibility"; odgovoran "responsible" → odgovornost "responsibility"; siguran "safe/certain" → sigurnost "safety, certainty". This is how formal Croatian converts "it is possible that X" into "the possibility of X".
| Adjective | Abstract noun (-ost) | English |
|---|---|---|
| moguć | mogućnost | "possibility" |
| odgovoran | odgovornost | "responsibility" |
| spreman | spremnost | "readiness, willingness" |
Postoji mogućnost da odgodimo sastanak.
There's a possibility we'll postpone the meeting. — 'mogućnost' nominalizes 'it's possible'; here it still heads a da-clause.
Spremnost na suradnju ovdje je ključna.
Willingness to cooperate is key here. — abstract 'spremnost' carries the whole quality as a subject noun.
Condensing a clause into a noun phrase
The real power of nominalization is condensation: an entire subordinate clause collapses into a single noun phrase, which makes the sentence shorter, denser, and more impersonal. The classic case is a temporal clause. Spoken Croatian says nakon što je došao "after he came", with a full finite clause; written Croatian condenses it to nakon dolaska "after the arrival", where the verbal noun dolazak absorbs the verb and the conjunction disappears.
| Clause (spoken) | Nominalized (formal) | English |
|---|---|---|
| nakon što je došao | nakon dolaska | "after (his) arrival" |
| prije nego što su otišli | prije odlaska | "before (their) departure" |
| zato što su odlučili | zbog odluke | "because of the decision" |
Nakon dolaska gostiju počela je svečana večera.
After the guests' arrival the formal dinner began. — the clause 'after the guests arrived' condensed into 'nakon dolaska gostiju'.
Zbog kašnjenja vlaka propustili smo vezu.
Because of the train's delay we missed our connection. — 'because the train was late' compressed into 'zbog kašnjenja vlaka'.
Donošenje odluke odgođeno je do sljedećeg tjedna.
The making of the decision has been postponed until next week. — doubly nominal: 'donošenje' (verbal noun) + genitive 'odluke' (itself an -a noun).
Notice how each condensed version stacks genitives — dolaska gostiju, kašnjenja vlaka — which is the visual signature of formal Croatian: a chain of "of" relationships where speech would have used verbs and conjunctions.
The register effect — and its limits
Nominalization is what makes a text read as formal, dense, and impersonal. Because the action becomes a noun, the doer can quietly vanish (nakon dolaska names no one), tense and aspect blur, and the sentence acquires the flat, official tone of a regulation or an abstract. This is precisely why you want it in a report — and precisely why you should not overdo it in ordinary writing. A pile-up of -nje nouns and stacked genitives is the hallmark of bad bureaucratic prose, and Croatian style guides warn against the so-called imenički stil ("nominal style") just as English ones warn against nominalese.
Provedba mjera ovisi o suradnji svih sudionika.
The implementation of the measures depends on the cooperation of all participants. — heavily nominal: idiomatic in an official document, leaden in a friendly email.
Bilo je teško jer je padala kiša.
It was hard because it was raining. — the natural spoken version; nominalizing this ('zbog padanja kiše') would sound absurdly stiff.
Common Mistakes
❌ čitanje knjigu
Incorrect — the verbal noun cannot take an accusative object; the object must be genitive.
✅ čitanje knjige
the reading of the book — genitive object 'knjige'.
❌ Nakon dolaska gosti počela je večera.
Incorrect — the noun governing 'dolaska' needs its possessor in the genitive: 'gostiju', not nominative 'gosti'.
✅ Nakon dolaska gostiju počela je večera.
After the guests' arrival the dinner began. — genitive 'gostiju'.
❌ Mogućost da dođe je mala.
Misspelling — the abstract suffix is '-ost' on the full stem: 'mogućnost', with the 'n'.
✅ Mogućnost da dođe je mala.
The possibility that he'll come is small. — correct '-nost'.
❌ Hvala na pozivanju mene na zabavu.
Stilted — nominalizing a casual thank-you is unidiomatic; speech keeps the finite verb.
✅ Hvala što si me pozvao na zabavu.
Thanks for inviting me to the party. — natural finite clause; save the verbal noun for formal text.
Key Takeaways
- Nominalization recasts clauses as noun phrases and is the engine of formal Croatian (law, science, journalism).
- The verbal noun in -nje turns an action into a noun, and its former object becomes genitive (čitanje knjige, never knjigu) — read it as English "the …-ing of".
- The abstract noun in -ost turns a quality into a noun (moguć → mogućnost), converting "it is possible that" into "the possibility of".
- An entire subordinate clause can condense into a noun phrase: nakon što je došao → nakon dolaska, zato što su odlučili → zbog odluke — note the stacked genitives.
- Nominalization is a register dial: dense and impersonal when you want formality, leaden and bureaucratic when you don't — keep finite clauses for speech and warm prose.
