In order to conjugate a verb in the past tense, use the appropriate ending and add BITI (to be) in the appropriate form. The formula of past tense looks so: Verb in past tense + BITI is present.

Let’s consider it in practice:

Ja sam kupio

Ja sam kupila

I bought (a man says)

Ti si kupio

Ti si kupila

You bought (said to a man)

You bought (said to a woman)

On je kupio

Ona je kupila

Ono je kupilo

Mi smo kupile

We bought (m+m or m+w)

Vi ste kupile

You bought (m+m or m+w)

You bought (w+w)

Oni su kupili

One su kupile

They bought (m+m or m+w)

They bought (w+w)

Also, when/if we want to hide a personal pronoun, we can place BITI before the verb instead of after. For example Kupio sam – I bought, Kupili smo – We bought, and so on.

Irregular verbs:

Ići – to go, stem in past IŠA-

Doći – to come, stem in past DOŠA-

Reći – to say/to tell, stem in past REKA-

Negative and interrogative forms

In order to form the negative form of the Serbian present tense, use a form of BITI with the prefix –NI:

Ja nisam, ti nisi, on nije, mi mismo, vi niste, oni nisu;

And in order to form the interrogative form, place DA LI before the verb and pronoun:

Da li ja sam pevao? – Did I sing?

Da li smo mi putovali? – Did we travel?

Da li su radili? – Did they work? (notice, one can hide a pronoun, in this case – ONI)
