Kondicional - rečenice s „ako“

conditionals

Overview

Serbian marks hypothetical and counterfactual meaning with one mood, the кондиционал (also called потенцијал): би (бих, би, би, бисмо, бисте, би) plus the same радни глаголски придев (l-participle) already taught by past-tense-perfekat-a2 and participles-b1. Радио бих can mean either I would do or I would have done - Serbian builds no separate form for the two meanings.

Instead, which meaning is intended is signalled by the if-clause: a plain present (real/open condition), a би-conditional (hypothetical), or да + perfekat (counterfactual, something that did not happen). The rest of this lesson works through each in turn.

Real and potential conditions - ако + present

For a condition treated as realistic or likely, the ако-clause takes a plain present tense, and the result clause takes futur I or an imperative: „Ако имам времена, доћи ћу на журку.“ (If I have time, I'll come to the party.) This is by far the most common conditional pattern in everyday speech.

Ако + futur II (futur-ii-b1) is a genuine alternative to ако + plain present for the same real condition - it simply makes the future orientation more explicit: „Ако будеш имао времена, помоћи ћу ти.“ sits right next to „Ако имаш времена, помоћи ћу ти.“ with no change in meaning.

verb-aspect-pairs-b1's aspect choice still applies inside the ако-clause exactly as inside any other clause: „Ако купим карте на време, ићи ћемо на концерт.“ uses the perfective present-shaped купим for one bounded purchase, not the imperfective купујем.

Hypothetical and counterfactual conditions

For a condition seen as unlikely or purely hypothetical, both clauses switch to the би-conditional: „Ако бих имао времена, дошао бих на журку.“ (If I had time, I would come.) Once the if-clause commits to this register, the result clause has to match it - it cannot fall back to futur I.

For a genuine counterfactual - something that did not actually happen - Serbian replaces ако with да, and the if-clause takes perfekat instead of a би-form: „Да сам знао за журку, дошао бих.“ (Had I known about the party, I would have come.) Ако + perfekat here would instead read as an open question about the past („if it turns out I knew…“), not a closed, contrary-to-fact statement - да is what commits to the counterfactual reading.

Word order, aspect and the conditional passive

Би is itself an enclitic and follows word-order-enclitics-a2's rules exactly like сам or ће: second position, and it fronts directly with ли for yes/no questions just like they do - „Би ли дошао да те позовем?“ Би can also stand alone with no explicit ако-clause at all, as a general hedge or polite wish: „Она би волела да путује више.“ (She would like to travel more.)

Because the кондиционал is built from би + a participle, it combines with everything past-tense-perfekat-a2 and passive-voice-b1 already established: „Кућа би била продата да смо имали бољу понуду.“ (The house would have been sold if we'd had a better offer) stacks the counterfactual да-clause, the би-conditional, and the participial passive била продата in one sentence.

Examples

Ako imam vremena, doći ću na žurku.
If I have time, I'll come to the party.
Real/potential condition - plain present in the ако-clause, futur I in the result.
Ako bih imao vremena, došao bih na žurku.
If I had time, I would come to the party.
Hypothetical - би-conditional in both clauses.
Da sam znao za žurku, došao bih.
Had I known about the party, I would have come.
Counterfactual - да + perfekat, never ако, for something that did not happen.
Da nisam bio bolestan, otišao bih na posao.
If I hadn't been sick, I would have gone to work.
Negative counterfactual - same да + perfekat pattern.
Ona bi volela da putuje više.
She would like to travel more.
би standing alone with no ако-clause at all - a hedged, polite wish.
Kad bi svaki dan vežbao, bio bi u boljoj formi.
If he exercised every day, he'd be in better shape.
кад би substitutes for ако би in a general hypothetical; imperfective вежбао for a repeated action.
Ako kupim karte na vreme, ići ćemo na koncert.
If I buy the tickets on time, we'll go to the concert.
Perfective купим inside a real ако-clause - verb-aspect-pairs-b1's rule reapplied.
Kuća bi bila prodata da smo imali bolju ponudu.
The house would have been sold if we had had a better offer.
Conditional passive: би + била продата (passive-voice-b1), inside a counterfactual да-clause.
Da li bi došao da te pozovem?
Would you come if I invited you?
да ли + normal order is one way to ask this; би also fronts directly with ли - „Би ли дошао да те позовем?“.

Compared with…

English marks the real/hypothetical/counterfactual distinction with three different tense-shifted forms in the if-clause (if I have / if I had / if I had had) and two different result-clause forms (will / would / would have). Serbian needs only one result-clause form, би + participle, throughout - the ако/да-clause alone carries the distinction. Expect to translate both would and would have into the same Serbian би-form, disambiguated only by which if-clause construction it's paired with.

Serbian
Došao bih.
One Serbian form covers both English meanings - the if-clause (ако+present vs. да+perfekat) makes the distinction, not the result clause.
English
I would come. / I would have come.

Common mistakes

Wrong
Ako bih imao vremena, doći ću.
Right
Ako bih imao vremena, došao bih.
Once the if-clause commits to the hypothetical бих-conditional, the result clause must match it - it cannot switch to the real-conditional futur ћу.
Wrong
Ako sam znao, došao bih.
Right
Da sam znao, došao bih.
A genuine counterfactual (something that did not happen) needs да + perfekat; ако + perfekat instead reads as an open possibility about the past, contradicting the intended counterfactual meaning.
Wrong
Ona voli da putuje više.
Right
Ona bi volela da putuje više.
Plain present воли (likes) states a general fact; the hedged would like meaning needs the conditional би волела.
Wrong
Kuća bila bi prodata da smo imali bolju ponudu.
Right
Kuća bi bila prodata da smo imali bolju ponudu.
The enclitic би must sit in second position, right after кућа - not after the participle била.

Tips & exceptions

Tips
  • One би + participle form covers both would do and would have done - the ако/да-clause's own tense, not a different result-clause form, signals which meaning is intended.
  • Reach for да instead of ако specifically when the condition is contrary to what actually happened - real, open possibilities always keep ако.
  • Би behaves exactly like сам/ће in word-order-enclitics-a2's cluster: second position, and it fronts directly with ли for questions (Би ли...?) just like they do.
Exceptions
  • Ако + futur II (ако будем имао) is an ordinary, everyday alternative to ако + plain present for imperfective verbs - no register restriction, exactly as the section above already shows. The formal/written-register restriction (futur-ii-b1) applies only to perfective verbs, where futur II is the marked, less common option next to the default plain perfective present.
  • Кад би can substitute for ако би in hypothetical conditions with no real change in meaning, especially for general or habitual hypotheticals like „Кад би вежбао...“.

Summary

Serbian's кондиционал - би (бих/би/би/бисмо/бисте/би) + радни придев - covers both would do and would have done in one form. Real/potential conditions use ако + present (+ futur in the result); hypothetical conditions use ако + би-conditional in both clauses; counterfactual conditions switch to да + perfekat (+ би-conditional in the result). Би is an enclitic following word-order-enclitics-a2's rules, and it combines freely with verb-aspect-pairs-b1's aspect choices and passive-voice-b1's participial passive.
