Støvsugeren står i skabet, men i dag bruger jeg den ikke, fordi gulvet kun er lidt beskidt.

Because Danish usually puts the definite article on the end of the noun instead of using a separate word like the.

• en støvsuger = a vacuum cleaner
• støvsugeren = the vacuum cleaner
• et skab = a cupboard / closet
• skabet = the cupboard / closet
• et gulv = a floor
• gulvet = the floor

The ending depends on the noun’s gender:

• common gender nouns usually take -en
• neuter nouns usually take -et

So this sentence is a good example of how Danish builds definiteness directly onto the noun.

Because støvsuger is a common gender noun: en støvsuger. Common gender nouns are referred to with den.

• en støvsuger → den
• et skab → det
• et gulv → det

So jeg bruger den ikke means I don’t use it, where it refers back to støvsugeren.

Danish often uses more specific location verbs where English would just use is.

Here, står is natural because the vacuum cleaner is thought of as being stored upright or in a standing position.

Common Danish location verbs include:

• stå = stand
• ligge = lie
• sidde = sit
• hænge = hang

So:

• Støvsugeren står i skabet is more natural than just using a general verb like er.

In English, The vacuum cleaner is in the closet is enough, but Danish often prefers the more physical description.

i means in / inside, so i skabet means in the cupboard / closet.

The definite form skabet is used because we are talking about a specific cupboard, not just any cupboard.

Compare:

• i et skab = in a cupboard
• i skabet = in the cupboard

So the sentence points to a known or specific place.

This is because Danish main clauses follow the V2 rule: the finite verb normally comes in the second position.

If i dag is placed first, the verb must still stay second, so the subject comes after the verb:

• I dag bruger jeg den ikke.

If the subject comes first, then the verb follows it:

• Jeg bruger den ikke i dag.

Both are possible, but the first version gives extra focus to today.

In Danish, short object pronouns like den, det, ham, hende often come before ikke in a main clause.

So:

• Jeg bruger den ikke. = correct and natural

With a full noun phrase, the position is often different:

• Jeg bruger ikke støvsugeren.

So this is a very common pattern:

• pronoun object → before ikke
• full noun object → often after ikke

That is why den ikke sounds natural here.

Danish does not have a separate present continuous form like English am using.

The simple present bruger can mean:

• use
• am using

The time phrase i dag makes the meaning clear.

So:

• I dag bruger jeg den ikke
  can naturally mean
• Today I’m not using it

This is completely normal in Danish.

Because fordi introduces a subordinate clause, and subordinate clauses usually have different word order from main clauses.

In a main clause, you would normally say:

• Gulvet er kun lidt beskidt.

After fordi, Danish typically uses subordinate-clause order:

• fordi gulvet kun er lidt beskidt

So the adverb kun comes before the finite verb er.

This is a very important pattern to notice:

• main clause: Gulvet er kun lidt beskidt
• subordinate clause: fordi gulvet kun er lidt beskidt

They do different jobs:

• kun = only / just
• lidt = a little / slightly

So:

• lidt beskidt = a little dirty
• kun lidt beskidt = only a little dirty

In the sentence, kun limits the amount of dirt, and lidt modifies the adjective beskidt.

Together they make the reason sound mild: the floor is not very dirty, so vacuuming is unnecessary.

The comma before men is standard because men joins two main clauses:

• Støvsugeren står i skabet
• men i dag bruger jeg den ikke

The comma before fordi marks the start of a subordinate clause:

• fordi gulvet kun er lidt beskidt

In Danish, this comma is part of the traditional grammatical comma system. In modern Danish, some writers omit this kind of comma, but many texts still include it. So the punctuation in your sentence is normal and common.
