Verb Aspect

Level 2Sounds Like glagolski vid: nesvršeni i svršeni

In Serbian, every verb has an inherent aspect (glagolski vid). The imperfective aspect (nesvršeni vid) describes ongoing processes, repetitions, or general facts. The perfective aspect (svršeni vid) describes an action viewed as a completed whole, a single boundary, or an achieved result.

How It Works

Verbal aspect (глаголски вид) is an essential part of the Serbian verbal system. Whenever you speak, you choose whether to view the action as an ongoing process or as a completed whole.

1. Imperfective Aspect (Несвршени вид)
Used for:

  • Actions happening right now: Сада пишем писмо. (I am writing a letter right now.)
  • Continuous processes: Цео дан сам читао књигу. (I was reading a book all day.)
  • Habitual or repeated events: Сваког јутра пијем кафу. (Every morning I drink coffee.)
  • Complements after phasal verbs like почети, наставити, престати (which strictly forbid perfective verbs: Почео сам да читам, never *да прочитам).

2. Perfective Aspect (Свршени вид)
Used for:

  • A single completed action with a definite result: Написао сам домаћи. (I finished my homework.)
  • Instantaneous or punctual events: лупнути (to knock once), купити (to buy).
  • Actions viewed within a time boundary (за + accusative): Прочитао сам чланак за десет минута. (I read the article in ten minutes.)

3. Biaspectual Verbs (Двовидски глаголи)
Not all Serbian verbs exist in distinct morphological pairs. Some verbs can function as either imperfective or perfective depending entirely on context:

  • Common everyday native verbs: видети (to see), чути (to hear), ручати (to have lunch), вечерати (to have dinner). For example, Сада ручам (imperfective: I am having lunch now) vs. Кад ручам, идемо у град (perfective: Once I finish lunch, we will go to town).
  • Many borrowed verbs ending in -овати and -ирати: организовати (to organise), информисати (to inform), телефонирати (to telephone).

4. How Aspect Pairs Are Formed
Serbian paired verbs are typically created through:

5. Present Tense Nuances and Modal Complements
While imperfective verbs express the real-time 'here-and-now' present, perfective present forms cannot describe an ongoing event happening right before your eyes. They are used mainly in dependent clauses (e.g., чим стигнем – as soon as I arrive) and habitual or narrative contexts.

Importantly, while phasal verbs exclusively take imperfective verbs, modal verbs freely combine with both aspects based on your goal: Морам да радим (imperfective: I have to work / spend time working) versus Морам да урадим домаћи (perfective: I have to finish my homework).

  1. Целог поподнева сам писао извештај и коначно сам га написао.

    I was writing the report all afternoon, and I finally finished writing it.

    Word by Word: All afternoon AUX wrote report and finally AUX it wrote-finish.

    Shows the contrast in past tense: imperfective 'писао' marks the long ongoing process, while perfective 'написао' marks the finished result.

  2. Тренутно гледам филм, а чим га погледам, јавићу ти се.

    I am currently watching a movie, and as soon as I finish watching it, I will get in touch with you.

    Word by Word: Currently watch movie, and as-soon-as it watch-finish, will-call to-you self.

    The real-time present uses imperfective 'гледам'. The subordinate clause introduced by 'чим' uses the perfective present 'погледам' to mark prior completion.

  3. Сваког дана пијем чај, али сада ћу брзо попити ову шољу.

    Every day I drink tea, but now I will quickly drink up this cup.

    Word by Word: Every day drink tea, but now will quickly drink-up this cup.

    Imperfective 'пијем' marks a daily habit, whereas perfective 'попити' indicates consuming a single specific drink completely.

  4. Почео је да чита нову књигу јутрос.

    He began reading a new book this morning.

    Word by Word: Began AUX to read new book this-morning.

    Phasal verbs like 'почети' (to begin) require an imperfective verb complement ('чита'), because an event must have duration to have phases.

Common Mistakes

  • Using a perfective present verb for an action happening right now in an independent clause

    Сада напишем поруку пријатељу.
    Сада пишем поруку пријатељу.

    The perfective present cannot describe an ongoing event in real time. To express what you are doing right now, use the imperfective form 'пишем'.

  • Using a perfective verb after phasal verbs like 'begin', 'continue', or 'stop'

    Почео је да прочита књигу.
    Почео је да чита књигу.

    Phasal verbs (почети, наставити, престати) describe a stage of an unfolding action and strictly take imperfective complements.

  • Pairing a perfective verb directly with durative time periods instead of 'за' + accusative

    Урадио је домаћи два сата.
    Урадио је домаћи за два сата.

    A simple duration like 'два сата' measures how long a continuous process lasted (requiring imperfective 'радио је'). For a completed outcome, use 'за два сата' (in two hours).
