-nje and -ost: a noun from a verb, a noun from an adjective

Grown-up speech leans on nouns the language did not start with: they are made out of verbs and adjectives. Two suffixes do that work, and both behave without surprises. For example: “Ажурирање је стигло ноћас и променило подешавања” — The update arrived overnight and changed the settings. A rule from the Serbian course: worked out on examples, not memorized as a wording.

How it works

Grown-up speech leans on nouns the language did not start with: they are made out of verbs and adjectives. Two suffixes do that work, and both behave without surprises.

From a verb comes -nje: ažurirati → ažuriranje (an update), ponašati se → ponašanje, saosećati → saosećanje. All of them are neuter and bend like polje.

From an adjective comes -ost: usamljen → usamljenost (loneliness), pouzdan → pouzdanost, moguć → mogućnost. All of them are feminine: bez mogućnosti, o usamljenosti.

Why that is worth knowing. Meeting an unfamiliar uverenje, you know straight away it is neuter. Meeting pouzdanost, you know it is feminine and gives pouzdanosti.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
