If you have been studying Serbian for a little while, you already know that verbs change their form depending on tense. The jump from present to past can feel like a big leap at first - but with a little practice it quickly becomes second nature. This gap-fill exercise is designed to make that jump feel natural and even a little fun.
Below you will find everything you need: a short explanation, a video to listen along with, a reference table, and a practical tip. Work through it at your own pace and do not worry about making mistakes - that is exactly what exercises are for.
What is this exercise?
This is a present and past tense conjugation gap-fill with instant feedback. You hear or read a Serbian sentence, decide whether the verb belongs in the present or the past, and fill in the correct form. The focus is on first-person and second-person forms because those are the ones you reach for most often in everyday conversation - talking about yourself and asking about someone else.
The exercise works best when you say each answer aloud before writing it. Your ear will often catch a wrong form before your grammar knowledge does, so trust both together.
Hear it (carried forward)
Watch the original companion video below. Listen carefully to how each verb form sounds - Serbian pronunciation is very consistent, so what you hear is exactly what you write.
Present vs past at a glance
The table below shows three common verbs side by side in the present and the simple past (the perfective past formed with the auxiliary sam/si/je and the verbal adjective). Study the pattern, then try the gap-fill with the video.
| Infinitive | Present (I ...) | Past (I ...) | Meaning |
|---|---|---|---|
| raditi | radim | radio sam / radila sam | I work / I worked |
| govoriti | govorim | govorio sam / govorila sam | I speak / I spoke |
| pevati | pevam | pevao sam / pevala sam | I sing / I sang |
Notice how the present tense ending for first person is always -m. The past tense is a two-word construction: the short form of the verb biti (to be) plus the verbal adjective. The verbal adjective is the part that changes according to gender and number.
A tip about participle endings
The verbal adjective (sometimes called the past participle in textbooks) ends in -o for masculine singular, -la for feminine singular, and -lo for neuter singular - so a man says radio sam while a woman says radila sam. Once you remember those three little endings, the past tense of almost every Serbian verb suddenly becomes predictable and manageable. It is one of the most satisfying "click" moments in learning the language, so look out for it.
Gap-fill: try it yourself
Read each sentence and fill in the blank with the correct present or past form. The verb you need is given in brackets. Say the answer aloud before you check.
- Svaki dan ______ srpski. (uciti - present, I)
- Juče ______ ceo dan. (raditi - past, I, masculine)
- Ti ______ veoma lepo. (pevati - present, you singular)
- Ona ______ o tome ceo sat. (govoriti - past, she)
- Mi ______ zajedno svako jutro. (trčati - present, we)
Answers: (1) ucim, (2) radio sam, (3) pevaš, (4) govorila je, (5) trcimo. How did you do? Do not worry if you missed one - go back to the table and try again.
Frequently asked questions
Do I always need the auxiliary verb in the past tense?
Yes, in everyday speech you always use the short-form auxiliary (sam, si, je, smo, ste, su) together with the verbal adjective. The only exception is in older literary or poetic style, where the auxiliary can sometimes be omitted in third-person forms.
What if I am a woman - do I always use the -la ending?
Yes. If you are a woman, you say radila sam, govorila sam, pevala sam. Serbian verbal adjectives agree with the grammatical subject, so your gender determines the ending every time.
Is the verbal adjective the same as the past participle in English?
It plays a similar role but it is not identical. In Serbian it can only be used to form the past tense together with the auxiliary; it cannot be used alone as an adjective the way English past participles sometimes can. Think of it as its own category and you will avoid confusion.
Can I practise this kind of exercise with other verbs?
Absolutely. Take any infinitive you know, drop the -ti ending, add the correct present-tense suffix, or build the past tense with the auxiliary plus the verbal adjective. The more verbs you run through this process with, the more automatic it becomes.
How long does it take before verb forms feel automatic?
Most learners find that two to three weeks of daily short practice - even just five minutes - is enough for the most common verbs to feel natural. Consistency matters far more than long study sessions.
I hope this exercise gives you a clear, satisfying sense of how present and past tenses work side by side in Serbian. You are building something real with every sentence you practise, and that is worth celebrating. Keep going - it gets easier every day.
