Aspect in the Future

Future time does not choose Serbian aspect for you. Future I accepts imperfective and perfective verbs: imperfective opens a future process, habit, or repeated effort; perfective presents one bounded result. Future-oriented present forms and future II add their own tense and clause meanings on top of that viewpoint choice.

This page assumes you already know how future I and future II are formed. For auxiliary paradigms and spelling, use Future I and Future II.

Future I: Process versus Result

Use the same lexical pair and change only the intended viewpoint:

Imperfective писати promises or predicts engagement in the activity; it does not assert that the final report will be ready. Perfective написати includes the relevant endpoint.

The contrast is not identical to English will be writing versus will write. English simple future can describe either process or completion:

Plans and Predictions Can Use Either Aspect

A plan does not automatically require perfective aspect. Compare two plans for the same afternoon:

Imperfective разговарати presents the future activity. Perfective поразговарати packages each conversation as a bounded encounter. The prefix also contributes a delimited-event nuance, so these are related members of a lexical network, not tense forms.

Predictions show the same choice:

Чекати presents duration; сачекати presents waiting through to a relevant point. Neither is selected merely because ћемо marks future time.

Habits, Repetition, and Repeated Attempts

An imperfective future is the default for an open recurring activity.

Perfective can appear inside a repeated frame when every occurrence reaches a boundary:

The distributive phrase по једно поглавље creates a series of bounded reading events. Repeated future effort often combines an imperfective attempt verb with a perfective target:

Покушаваћу presents repeated effort; perfective решим names the sought result. Two verbs in one clause can therefore carry different aspects for different reasons.

Future-Oriented Present in Subordinate Clauses

After temporal and conditional conjunctions such as кад, чим, ако, Serbian commonly uses a morphologically present form with future reference. A perfective present naturally marks a future boundary.

Perfective припремим/прочиташ is present in form but future-oriented in these subordinate clauses. This alone disproves the idea that perfective means past.

An imperfective present can occur when the clause describes an ongoing or habitual future frame:

Tense and aspect contribute separate information: present morphology is licensed by the subordinate construction; imperfective радиш presents an open activity.

In an ordinary future time clause, do not copy English will mechanically. Future I belongs in an embedded question, however:

The first кад introduces a temporal relation and uses perfective present стигнем. The second када asks for unknown future time inside an indirect question, so future I ћу стићи is normal.

Future II: A Future Situation Viewed Relatively

Future II occurs in subordinate clauses and locates a situation relative to another future event. Aspect still chooses the view inside that situation.

Imperfective future II presents an activity or state that will be in progress or hold under the stated condition:

The l-participles читао/радила agree with the subordinate subject. Perfective future II can emphasize that completion stands before the main future reference point:

In many temporal clauses, simpler кад прочитам is more idiomatic and sufficient. Future II is useful when the relative future frame or prior completion is being made explicit; it is not a mandatory future perfect translation.

A Four-Way Comparison with One Pair

The table is not an automatic translation chart. The conjunction and tense form frame the future relation; aspect tells whether the contract-reading is open or bounded.

Practice Tasks

Task 1: Change the Commitment

Promise future reading first as an activity, then as a completed result.

Task 2: Choose a Subordinate Future

Express simultaneous future activity, then a completion that triggers the next event.

Common Mistakes

Assuming future reference requires perfective

Treating perfective as past

Using future I in an ordinary temporal clause

Equating English progressive with Serbian imperfective in every future

Key Takeaways

• Future I takes both aspects: imperfective opens a process or pattern; perfective commits to a boundary.
• Future time does not turn perfective into a tense or make imperfective unavailable.
• Perfective present commonly carries future reference after кад, чим, ако.
• Future II supplies a relative future frame; aspect still distinguishes activity from completion.
• English simple, progressive, and perfect future forms do not map mechanically onto Serbian aspect.
