You've learned the wonderfully simple Swedish present tense – great! Now, how do you talk about things that have already happened? Like English, Swedish uses different past tenses to convey nuances about when an action occurred and its connection to the present.

The two most common and essential past tenses you'll encounter are the Preteritum (often similar to the English Simple Past) and the Perfekt (often similar to the English Present Perfect). Understanding how they're formed and when to use each is key to discussing past events accurately. Let's dive in!

Preteritum (Simple Past)

The Preteritum is used to talk about actions that were **completed in the past**, often at a specific, finished time. Think of it like the English Simple Past ("I walked," "She ate," "They visited").

How to Form the Preteritum:

Forming the Preteritum involves different endings depending on the verb group (similar patterns to the present tense, but different endings). Again, the form is the **same for all subjects** (jag, du, han, hon, etc.).

• Group 1 (Infinitive ends in -a): Often adds -ade. att tala (to speak) -> talade (spoke) att arbeta (to work) -> arbetade (worked)
• Group 2 (Often ends in consonant or short vowel): Often adds -te or -de (depending on the final consonant sound). att stänga (to close) -> stängde (closed) att ringa (to call) -> ringde (called) att köpa (to buy) -> köpte (bought)
• Group 3 (Short verbs, often ending in vowel other than -a): Often adds -dde. att bo (to live) -> bodde (lived) att må (to feel) -> mådde (felt)
• Group 4 (Strong/Irregular verbs): These change significantly, often with a vowel shift (omljud), and don't follow a simple ending rule. They must be memorized. att dricka (to drink) -> drack (drank) att skriva (to write) -> skrev (wrote) att vara (to be) -> var (was/were) att ha (to have) -> hade (had) att gå (to go/walk) -> gick (went/walked)

When to Use Preteritum:

• Completed actions at a specific past time: Jag arbetade igår. (I worked yesterday.)
• Past events in a story or sequence: Han vaknade, åt frukost och gick till jobbet. (He woke up, ate breakfast, and went to work.)
• States or situations that were true in the past but aren't anymore: Hon bodde i London förut. (She lived in London before.)

Perfekt (Present Perfect)

The Perfekt describes actions that happened in the past but have a **connection to the present**, or happened at an **unspecified past time**. It often translates to the English Present Perfect ("I have spoken," "She has eaten").

How to Form the Perfekt:

The Perfekt is a compound tense formed with the **present tense of the auxiliary verb har (to have)** plus a special form of the main verb called the **Supinum**.

har + Supinum

The Supinum Form:

The Supinum is a verb form used almost exclusively to form the Perfekt (and the Pluskvamperfekt, past perfect). Luckily, for most verbs, it's often formed by adding -t to the verb stem (the infinitive minus -a), similar to how neuter adjectives are formed.

• Group 1: Infinitive tala -> Stem tal -> Supinum talat
• Group 2: Infinitive stänga -> Stem stäng -> Supinum stängt
• Group 3: Infinitive bo -> Stem bo -> Supinum bott (Note the double 't')
• Group 4 (Irregular): Supinum forms are irregular and must be learned. dricka -> Supinum druckit skriva -> Supinum skrivit vara -> Supinum varit gå -> Supinum gått

When to Use Perfekt:

• Actions completed at an unspecified time in the past: Jag har läst den boken. (I have read that book. - When doesn't matter).
• Actions that started in the past and continue to the present (often with i [for duration] or sedan [since]): Vi har bott här i fem år. (We have lived here for five years.)
• Past actions with results in the present: Jag har tappat mina nycklar! (I have lost my keys! - Implication: I don't have them now).
• Life experiences: Har du varit i Sverige? (Have you been to Sweden?)

Preteritum vs. Perfekt: Key Differences

Choosing between them can sometimes be tricky, as usage can overlap or differ slightly from English.

• Focus on Finished Time? If the action happened at a definite, finished past time (igår - yesterday, förra veckan - last week, år 2000 - year 2000), **Preteritum** is usually preferred. Jag besökte min vän igår. (I visited my friend yesterday.)
• Focus on Present Relevance/Result? If the past action has a connection or result now, or the time is unspecified, **Perfekt** is often used. Jag har besökt Stockholm många gånger. (I have visited Stockholm many times. - Experience, unspecified when). Han har brutit benet. (He has broken his leg. - Result: his leg is broken now).
• Conversation vs. Narrative: Perfekt is very common in conversation for recent past events, while Preteritum is more common for storytelling or recounting a sequence of finished events.

Start Talking About Yesterday!

Learning the Preteritum and Perfekt forms opens up your ability to share past experiences and stories in Swedish. Focus on memorizing the past forms (especially irregular ones!) and the Supinum form used with har. Practice distinguishing when an action is seen as purely finished (Preteritum) versus having relevance now (Perfekt).
