Bli-Passive
Bli-passiv
Bli-Passive in Swedish
Overview
Swedish has two main ways to form the passive voice: the s-passive (byggas) and the bli-passive (bli byggd). At the B2 level, understanding the difference between them is essential for nuanced expression. While the s-passive emphasizes processes and general truths, the bli-passive highlights the action, the change, or the specific event.
The bli-passive is formed with bli (become) + past participle and is more common in spoken Swedish than the s-passive. It feels more dynamic and concrete, making it the natural choice when you want to emphasize that something happened to someone or something.
Learning when to choose the bli-passive over the s-passive -- and understanding the additional vara-passive (for states/results) -- gives you the full toolkit for expressing passive meaning in Swedish with precision.
How It Works
Formation
Bli (conjugated for tense) + past participle (agreeing in gender and number):
| Tense | Bli Form | + Past Participle | Example |
|---|---|---|---|
| Present | blir | byggd/byggt/byggda | Huset blir byggt. |
| Past | blev | byggd/byggt/byggda | Huset blev byggt. |
| Perfect | har blivit | byggd/byggt/byggda | Huset har blivit byggt. |
| Future | ska bli | byggd/byggt/byggda | Huset ska bli byggt. |
Past participle agreement
The past participle must agree with the subject in gender and number:
| Subject | Participle Form | Example |
|---|---|---|
| En-word singular | -d | Bilen blev stulen. (The car was stolen.) |
| Ett-word singular | -t | Fönstret blev krossat. (The window was smashed.) |
| Plural | -da/-de | Böckerna blev sålda. (The books were sold.) |
Common past participle patterns:
| Verb Group | Infinitive | En-form | Ett-form | Plural |
|---|---|---|---|---|
| Group 1 | stänga | stängd | stängt | stängda |
| Group 2 | läsa | läst | läst | lästa |
| Group 4 | skriva | skriven | skrivet | skrivna |
| Group 4 | välja | vald | valt | valda |
| Irregular | göra | gjord | gjort | gjorda |
When to use bli-passive
1. Specific events and actions (something happened):
- Fönstret blev krossat av en sten. (The window was smashed by a stone.)
- Han blev överraskad. (He was/got surprised.)
2. Change of state (becoming):
- Hon blev vald till ordförande. (She was elected chairperson.)
- Vi blev inbjudna till festen. (We were invited to the party.)
3. When the agent is important:
- Boken blev läst av alla. (The book was read by everyone.)
- Huset blev byggt av ett lokalt företag. (The house was built by a local company.)
Three passives compared
| Construction | Form | Focus | Example |
|---|---|---|---|
| S-passive | verb + s | Process, general truth | Huset byggs nu. (being built - process) |
| Bli-passive | bli + participle | Event, change | Huset blev byggt förra året. (was built - event) |
| Vara-passive | vara + participle | State, result | Huset är byggt. (is built - completed state) |
Key distinctions:
| Scenario | Best Choice | Example |
|---|---|---|
| Sign/general rule | S-passive | Dörren stängs kl. 22. |
| Specific past event | Bli-passive | Dörren blev stängd av vinden. |
| Current state/result | Vara-passive | Dörren är stängd. |
Agent phrase
Use av (by) for the agent:
- Boken blev skriven av en svensk författare. (The book was written by a Swedish author.)

Common Mistakes
Wrong: Han blev överraska. Right: Han blev överraskad. Why: The past participle must be in the correct form. For en-word subjects, use the -d form (överraskad), not the infinitive.
Wrong: Fönstren blev krossat. Right: Fönstren blev krossade. Why: The past participle must agree in number. Fönstren (the windows) is plural, so use the plural participle krossade.
Wrong: Huset blev byggt. (when you mean it is currently built/standing) Right: Huset är byggt. (state) or Huset blev byggt 1920. (event) Why: For the current state or result, use vara + participle. Bli emphasizes the action/change, not the resulting state.
Wrong: Bilen blev säljd igår. Right: Bilen blev såld igår. Why: The past participle of sälja is såld/sålt/sålda (irregular). Use the correct irregular form, not a regular derivation.
Wrong: Using bli-passive for general truths: Kaffe bli druckit i Sverige. Right: Kaffe dricks i Sverige. (S-passive for general truths) Why: General truths and processes call for the s-passive. The bli-passive is for specific events and changes.
Usage Notes
The bli-passive is more common in spoken Swedish than the s-passive. When Swedes narrate events, describe what happened, or report news, the bli-passive is the natural choice. In contrast, the s-passive dominates in signs, instructions, and formal writing about processes.
The emotional or experiential bli-passive (blev förvånad, blev besviken, blev glad) blurs the line between passive voice and a bli + adjective construction (meaning "to become"). In practice, the distinction does not matter much -- the pattern is the same.
The vara-passive (result state) is important to distinguish from the bli-passive. Compare: Dörren blev stängd klockan tio (The door was closed at ten -- event) vs. Dörren var stängd när vi kom (The door was closed when we arrived -- state).
No significant regional variation exists in bli-passive usage across Sweden or Finland-Swedish.
Practice Tips
Three-passive drill -- take a verb like stänga (close) and write three sentences using all three passive forms: s-passive (Dörren stängs kl. 22), bli-passive (Dörren blev stängd av vinden), vara-passive (Dörren var stängd). Repeat with five different verbs.
News narration -- describe a recent news event using bli-passive: Mannen blev gripen. Pengarna blev hittade. Brottslingen blev dömd. This practices the most natural register for bli-passive.
Participle agreement practice -- write the past participle of ten common verbs in all three forms (en/ett/plural) and use each in a sentence with bli. This locks in the agreement patterns.
