Počeo je da radi: phase verbs, after which no to-form survives

The English "started to work" sounds bookish and rare in Serbian. Living Serbian says počeo je da radi. For example: “Почели смо да радимо у седам и завршили посао у пет” — We started working at seven and finished the job at five. A rule from the Serbian course: worked out on examples, not memorized as a wording.

How it works

The English "started to work" sounds bookish and rare in Serbian. Living Serbian says počeo je da radi.

The rule is one: after such a verb comes da plus the present. Počeo sam da radim, nastavio je da priča, prestali smo da čekamo.

And the person in the second half matches the first. Počeo sam da radim, never "da radi". That is the main source of first-year slips.

So behave početi, nastaviti, prestati, krenuti, uspeti and planirati. But prekinuti, obustaviti and završiti take a noun instead: prekinuo je razgovor, završili smo posao.

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.
