The past tense in Serbian is incredibly straightforward to learn.

You only need to know one past tense to talk about anything that happened before right now.

This tense is called the perfekt in Serbian.

Unlike English, you don’t have to learn a dozen different past tenses.

I’ll show you exactly how to form the Serbian past tense using two simple steps.

What is the Serbian past tense?

The Serbian past tense is a compound tense.

This simply means that you need two different words to create it.

You need a helping verb and a main action verb.

This is very similar to how we say “I have worked” in English.

You just combine the short form of the verb “to be” with a special past tense version of your action verb.

Step 1: the helping verb

The first piece of the puzzle is the helping verb.

In Serbian, we use the short forms of the verb biti (to be) as our helping verbs.

You must choose the correct helping verb based on who is doing the action.

Here’s the table of the helping verbs you need to memorize.

Step 2: the action verb

The second piece of the puzzle is the main action verb.

This is called the L-participle, but you can just think of it as the “past tense action word”.

To create this word, you take the infinitive form of a verb and remove the final -ti.

For example, the verb raditi (to work) becomes radi-.

Then, you add a specific ending to that root word.

The ending you choose depends on the gender and the number of the person doing the action.

Here are the endings you need to add to the verb root.

If a man wants to say he worked, he adds -o to get radio.

If a woman wants to say she worked, she adds -la to get radila.

Sentence structure and word order

Now we just put the pieces together.

The basic sentence structure is: Pronoun + Helping Verb + Action Verb.

Here’s how a man says “I worked”.

Here’s how a woman says “I worked”.

Here’s how you say “We read”, using the verb čitati (to read).

However, there’s a very important word order rule in Serbian.

Serbians almost always drop the pronouns (ja, ti, on, mi, vi, oni) when speaking.

But short helping verbs (sam, si, je…) are never allowed to be the first word in a sentence.

If you drop the pronoun, the action verb and the helping verb must swap places.

This reversed word order is the most natural and common way to speak in the Serbian past tense.

Making sentences negative

To say that someone didn’t do something, you need the negative forms of the helping verb.

You don’t use sam, si, je, smo, ste, su.

Instead, you use the negative forms: nisam, nisi, nije, nismo, niste, nisu.

Unlike the positive helping verbs, these negative words are allowed to sit at the front of a sentence.

You don’t need to flip the word order when dropping the pronoun.

Asking questions in the past tense

Asking a question about the past is also very simple.

You just put the phrase da li at the beginning of your sentence.

The word da is followed immediately by the short helping verb, and then your action verb.

This da li structure is the easiest and most reliable way to ask past tense questions in Serbian.
