Abstract nouns (-ost)

Abstract Nouns with -ost

In Croatian, you can easily turn adjectives into abstract nouns to discuss concepts, philosophy, and ethics. You do this by adding the suffix -ost to the adjective stem.

honesty
iskrenost

Crucially, all abstract nouns ending in -ost are feminine, even though they end in a consonant rather than the typical -a.

Honesty and the importance of truth are always connected.
Iskrenost i važnost istine su uvijek povezane.
If perfect equality existed, we would have justice.
Kad bi savršena jednakost postojala, imali bismo pravednost.

Many of these philosophical concepts come in contrasting pairs, giving you the vocabulary to debate existential topics.

Objectivity is hard, while subjectivity is completely natural.
Objektivnost je teška, dok je subjektivnost potpuno prirodna.

Because these are feminine nouns ending in a consonant, they follow a special declension pattern (often called the i-declension). When you need to use them in the genitive or locative cases, you will see the ending -i added to the word (for example, moralnost becomes moralnosti, and složenost becomes složenosti).

We often discuss the complexity of morality.
Često raspravljamo o složenosti moralnosti.
I am afraid of transience, and I dream of infinity.
Strah me je prolaznosti, a sanjam o beskonačnosti.

Adding -ost is a highly productive pattern in Croatian. If you know the underlying adjective, you can quickly form the abstract noun and elevate your discussions.

Is objectivity possible when we understand transience?
Je li objektivnost moguća kad razumijemo prolaznost?
