In order to form the past tense in the Serbian language, you need to know how to conjugate the verb BITI – to be, in the present tense, and know the endings of verbs in the past tense that we will consider now.

The conjugation in the past tense depends on gender and number. There are 3 genders in the Serbian language: masculine, feminine, and neuter. In order to use a past tense ending, drop –TI and add an appropriate one:

Singular Plural
Masculine -O -LI
Feminine -LA -LE
Neuter -LO -LA

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 the past tense looks like this: BITI in the present tense + verb with the past tense ending.

Let’s consider it in practice:

Kupiti  – to buy

Ja sam kupio

Ja sam kupila

I bought (a man says)

I bought (a woman 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

He bought

She bought

It bought

Mi smo kupili

Mi smo kupile

We bought (m+m or m+w)

We bought (w+w)

Vi ste kupili

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 place the verb first and BITI after it. For example Kupio sam – I bought, Kupili smo – We bought, and so on. Notice: the short forms of BITI (sam, si, je, smo, ste, su) always stand in the second position in the sentence: with a pronoun we say Ja sam kupio, and without a pronoun Kupio sam — never Ja kupio sam.

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 past tense, use a form of BITI with the prefix NI-:

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

And in order to form the interrogative form, place DA LI at the beginning of the sentence:

Da li sam ja 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)
