Verbal Nouns in -anje / -enje

Verbal nouns such as branje and učenje name activities and behave as neuter nouns. Their complements need the construction required by the noun rather than automatically preserving a verb's accusative object.

Branje is a noun, so branje knjig means reading of books with a genitive complement. It can become a subject with singular agreement, as in Plavanje je zdravo. An infinitive names an action too, but it does not follow this noun declension pattern.
