Глаголски вид
Overview
Almost every Serbian verb carries a grammatical category called вид (aspect): whether the action is a single, complete whole (свршени вид, perfective) or ongoing, repeated, or habitual (несвршени вид, imperfective). Most verbs come in pairs, one of each aspect, built on related but distinct forms: писати (impf., to write) / написати (pf., to write-and-finish).
This lesson introduces the concept and the handful of pairs you already half-know from past-tense-perfekat-a2 and future-tense-futur-a2; a systematic look at how pairs are built (prefixes, stem changes) comes later.
Perfective vs. imperfective - what changes
Imperfective describes an action in progress, repeated, or habitual, with no comment on whether it finished: „Читам књигу.“ (I am reading / I read a book - ongoing or habitual.) Perfective describes one single, whole action, usually with a result: „Прочитао сам књигу.“ (I have read the whole book - finished.)
The clearest test is a time phrase: цео дан (all day) or сваки дан (every day) forces imperfective, since a duration or a habit is not one bounded event; за сат времена (within an hour) or a flat statement of completion forces perfective.
Perfective verbs have no true present tense
This is the single most important fact in this lesson: a perfective verb's present-tense-shaped conjugation (напишем, купим, прочитам…) never means I am doing X right now - instead, it carries future or conditional meaning, most often inside a subordinate clause: „Кад прочитам књигу, рећи ћу ти шта мислим.“ (When I finish reading the book, I'll tell you what I think.)
Only imperfective verbs have a genuine, everyday present tense - the ongoing, right-now meaning belongs to imperfective alone.
Building pairs, and verbs with only one aspect
The most common pattern adds a prefix to an imperfective base to make it perfective - see the table below for the full list. Some pairs instead use two related but distinct stems: куповати (impf., already met in a1-shopping) / купити (pf.).
A few verbs are biaspectual, like ручати (to have lunch) and телефонирати (to phone); others exist in one aspect only, like имати (to have, from verb-imati-present-a1).
Tables
| Imperfective | Perfective | Meaning |
|---|---|---|
| писати | написати | to write |
| читати | прочитати | to read |
| радити | урадити | to do/work |
| гледати | погледати | to watch |
| куповати | купити | to buy |
Examples
Compared with…
English has no grammatical aspect marked on the verb itself; it leans on tense periphrasis instead (simple I wrote vs. progressive I was writing) or on separate words (finished writing, used to write). Serbian's choice between two entirely different verb forms - писати vs. написати - is a genuinely new category to notice, not just a new ending on a familiar idea.
Common mistakes
Tips & exceptions
- Ask one question first: is this a single, complete, whole action (often with a result), or something ongoing, repeated, or habitual? The first calls for perfective, the second for imperfective.
- Perfective verbs have no genuine present tense - their present-tense-shaped form (напишем, купим, прочитам…) always means future or once X happens, never right now.
- Learn a new verb together with its aspectual partner from day one (писати/написати, читати/прочитати) - the pairing is as fundamental as a noun's gender, not an optional extra.
- Biaspectual verbs (ручати, телефонирати) use one identical form for both aspects; only context tells them apart.
- Some pairs change the stem rather than just adding a prefix (куповати/купити, говорити/рећи) - learn these case by case rather than expecting a single rule.
- A handful of verbs exist in one aspect only with no natural partner: имати describes a state, not an event, so it has no perfective counterpart.
