Hvis jeg havde husket vaskekurven, ville jeg have taget tøjet med ned med det samme.

Because this sentence describes an unreal situation in the past: the speaker did not remember the laundry basket.

In Danish, that kind of idea is usually expressed with:

• hvis + past perfect in the if-clause
• ville have + past participle in the result clause

So:

• Hvis jeg havde husket ... = if I had remembered ...
• ville jeg have taget ... = I would have taken ...

By contrast, Hvis jeg huskede would normally sound more like an unreal or hypothetical situation in the present or as a less precise past-style phrasing, depending on context. In this sentence, havde husket is the standard and clear choice.

They belong to two different verb phrases:

• havde husket = had remembered
• ville have taget = would have taken

So:

1. havde is the auxiliary used to form the past perfect
2. have is the infinitive used after ville in the conditional perfect

This is very similar to English:

• if I had remembered
• I would have taken

Because Danish uses verb-second word order in main clauses.

The full sentence begins with the if-clause:

• Hvis jeg havde husket vaskekurven

After that, the main clause begins:

• ville jeg have taget tøjet med ned med det samme

In Danish main clauses, the finite verb usually comes in second position. Since the if-clause takes the first position, the finite verb ville must come immediately after it, before the subject jeg.

So Danish says:

• Hvis ..., ville jeg ...

not:

• Hvis ..., jeg ville ...

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

Tage ... med is a very common Danish verb expression meaning take ... along / bring ... with you.

In this sentence:

• have taget tøjet med ned = have taken the clothes down with me / downstairs

The particle med belongs with tage. Even though other words come in between, it still forms part of the verb expression.

This kind of split verb expression is common in Danish:

• tage noget med
• komme tilbage
• gå ud
• sætte sig ned

So taget ... med should be understood as one unit.

They do different jobs:

• med belongs to the verb phrase tage med = take along
• ned shows the direction down/downstairs

So:

• tage tøjet med = take the clothes along
• tage tøjet med ned = take the clothes down with you

The two particles are not redundant. One expresses accompaniment/bringing, and the other expresses direction.

Ned means down, often physically downward or downstairs depending on context.

In a sentence like this, it often suggests moving the clothes from one place in the home to a lower place, for example:

• from an upstairs room
• down to the laundry room
• down to a washing area

Danish often uses short directional adverbs like:

• op = up
• ned = down
• ind = in
• ud = out
• hen = over there

These are very common and often sound more natural than using a longer phrase.

Vaskekurven means the laundry basket, while en vaskekurv means a laundry basket.

The definite form is used because the speaker has a specific basket in mind, not just any basket. In everyday Danish, that is very natural when talking about familiar household objects.

Also, Danish often expresses definiteness by attaching it to the noun:

• en kurv = a basket
• kurven = the basket

And in compounds:

• en vaskekurv = a laundry basket
• vaskekurven = the laundry basket

It is a compound noun, which Danish uses very often.

It breaks down like this:

• vaske = wash / washing
• kurv = basket
• vaskekurv = laundry basket / washing basket
• vaskekurven = the laundry basket

Danish compounds are usually written as one word, unlike English, which may use one word, two words, or a hyphen depending on the expression.

This is something English speakers often need to get used to.

Tøjet is a very common collective noun meaning the clothes / clothing as a mass or set.

So here:

• tøjet = the clothes

By contrast, tøjerne would mean something more like the individual garments/items of clothing, and it is less natural in a sentence like this.

In everyday Danish, tøjet is usually the normal choice when talking about laundry, getting dressed, washing clothes, and so on.

Med det samme means immediately / right away / at once.

It is a fixed expression:

• med = with
• det samme = the same

But you should learn it as a whole phrase, because the literal pieces do not help much.

In this sentence, it tells you when the speaker would have taken the clothes down:

• ville jeg have taget tøjet med ned med det samme
  = I would have taken the clothes down immediately

In this sentence it comes naturally at the end:

• ... ville jeg have taget tøjet med ned med det samme

That final position is very common for time expressions and adverbial phrases in Danish.

You may hear adverbials in other positions too, but for learners, putting phrases like med det samme near the end is often a safe and natural choice.

Yes. This is the standard way to form the conditional perfect in Danish:

• ville have + past participle

Examples:

• ville have taget = would have taken
• ville have gjort = would have done
• ville have sagt = would have said

So the pattern is very close to English.

The verb is tage = to take.

Its principal forms are:

• tage = infinitive
• tog = past tense
• taget = past participle

It is an irregular verb, so the participle must simply be learned as taget.

This is one of the most common Danish irregular verbs, so it is worth memorizing early.

Not if you want the same meaning.

That version would sound more like:

• If I had remembered the laundry basket, I had taken the clothes down immediately

That does not work well as a normal English-style counterfactual result, and it is not the standard Danish way to express this meaning either.

For an unreal past result, Danish normally uses:

• Hvis jeg havde husket ..., ville jeg have taget ...

So ville have taget is important here.

Yes. In this sentence, huske takes the direct object vaskekurven.

So:

• at huske noget = to remember something

Here the speaker means they failed to remember the laundry basket—probably meaning they forgot to bring it or think of it at the relevant moment.

Danish often uses huske in a very similar way to English remember.

It is completely natural everyday Danish.

Nothing in it is especially formal, literary, or old-fashioned. It is a normal spoken and written way to express a past unreal condition.

The only reason it may feel advanced is the grammar pattern:

• Hvis + havde + past participle
• ville + subject + have + past participle

But the sentence itself is very ordinary Danish.
