Når opgaven er rettet, lægger jeg kladden i papirkurven.

Here Når means when in the sense of once/at the time that.

In this sentence, Når opgaven er rettet sets up the situation for the main action:

• When the assignment has been corrected / once the assignment is corrected...

A useful comparison:

• når = when (for something that happens generally, repeatedly, or in the future)
• da = when (for a specific event in the past)
• hvis = if

So here når is natural because the sentence is talking about what happens once that condition is met.

Opgaven means the assignment, while en opgave means an assignment.

Danish often uses the definite ending directly on the noun:

• en opgave = an assignment
• opgaven = the assignment

So:

• opgave = noun stem
• -n = the definite ending for this common-gender noun

The speaker is talking about a specific assignment, not just any assignment.

Er rettet is a very common Danish pattern. It can be understood as is corrected or has been corrected, depending on context.

Here:

• er = is
• rettet = past participle of rette

So opgaven er rettet literally looks like the assignment is corrected, but in natural English the sense is often:

• when the assignment has been corrected
• once the assignment is corrected

This is a standard way in Danish to describe a completed result or a passive idea.

In this context, rette means to correct, mark, or grade, especially for schoolwork.

So opgaven er rettet means the assignment has been checked/corrected by a teacher or reviewer.

Depending on context, English could translate it as:

• corrected
• marked
• graded

The exact English word depends on the school system and context, but the Danish is very natural.

This is one of the most important Danish word-order rules.

The sentence begins with a subordinate clause:

• Når opgaven er rettet

After that clause, the main clause starts. In Danish main clauses, the finite verb normally comes in second position. So after the initial clause, the verb comes before the subject:

• Når opgaven er rettet, lægger jeg kladden i papirkurven.

Not:

• Når opgaven er rettet, jeg lægger ...

This is often called the V2 rule:

• first element: Når opgaven er rettet
• second element: lægger
• then subject: jeg

English does not do this in the same way, so it often feels unusual to learners.

Danish often uses the present tense to talk about the future, especially when the future action is clear from context.

So:

• lægger jeg kladden i papirkurven can mean
• I put the draft in the wastepaper basket or more naturally in context:
• I’ll put the draft in the wastepaper basket

Because the sentence begins with Når and clearly refers to a later moment, Danish does not need a separate future form here.

Kladden means the draft, the rough copy, or the scribbled version.

It comes from:

• en kladde = a draft / rough version
• kladden = the draft

This usually refers to something unfinished, messy, or temporary, as opposed to a final clean version.

In school contexts, it can mean:

• rough notes
• a first draft
• a scrap version before the final copy

Yes. A close alternative is udkastet, which also means the draft.

But there is a slight nuance:

• kladden often suggests a rough, messy, scribbled version
• udkastet often sounds a bit more neutral or formal, like a draft version of a text

So kladden feels very natural if the speaker means a rough working copy that is going in the bin afterward.

Danish uses i because something goes into the wastepaper basket.

• i papirkurven = in/into the wastepaper basket

Compare:

• lægge noget i = put something in
• lægge noget på = put something on

So if the draft is being thrown away, i papirkurven is the natural choice.

Papirkurven literally means the paper basket or wastepaper basket.

It can be:

1. a real bin/wastepaper basket in a room
2. in some contexts, the computer recycle bin/trash

In this sentence, the most natural reading is the physical wastepaper basket.

Breakdown:

• papir = paper
• kurv = basket
• papirkurven = the wastepaper basket

Because Danish usually adds the definite article as an ending on the noun instead of using a separate word like English the.

So:

• en papirkurv = a wastepaper basket
• papirkurven = the wastepaper basket

This is the same pattern as:

• en opgave → opgaven
• en kladde → kladden

English learners often expect a separate word for the, but in Danish it is often attached to the noun.

Yes, but the tone changes slightly.

• lægger ... i papirkurven = put ... in the wastepaper basket
• smider ... i papirkurven = throw ... in the wastepaper basket

So smider sounds a bit stronger or more physical.
Lægger is more neutral and can sound slightly tidier or less forceful.

Both are possible, but lægger is perfectly natural here.

A rough pronunciation guide:

• Når ≈ nor
• opgaven ≈ OP-gay-vn or OP-gah-vn depending on accent
• er ≈ a very light air / a
• rettet ≈ RED-ed with a soft Danish d/t feel
• lægger ≈ LEH-ger
• jeg ≈ yai / yaih in careful speech, often reduced in fast speech
• kladden ≈ KLAD-en
• papirkurven ≈ pa-PEER-kur-ven

A few important pronunciation points:

• Danish g in opgaven is not always pronounced like a hard English g
• er is often very reduced in normal speech
• jeg is often much softer than learners expect
• rettet may sound less sharply pronounced than its spelling suggests

If you want to sound natural, the rhythm matters a lot:

• Når opgaven er rettet, lægger jeg kladden i papirkurven.

Because Når opgaven er rettet is a subordinate clause, and it is followed by the main clause.

So the comma separates:

• subordinate clause: Når opgaven er rettet
• main clause: lægger jeg kladden i papirkurven

This also helps you see the structure and understand why the word order in the main clause is lægger jeg rather than jeg lægger.
