Om morgenen tænder hun bruseren og lægger sin tandbørste ved håndvasken.

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

So when the sentence starts with Om morgenen, that phrase takes the first position, and the verb tænder must come next:

• Om morgenen tænder hun bruseren.

If you start with the subject instead, then you get:

• Hun tænder bruseren om morgenen.

Both are correct, but the word order changes depending on what comes first.

Om morgenen means in the morning or in the mornings, depending on context.

Danish often uses om + a definite time-of-day noun in fixed expressions like:

• om morgenen = in the morning
• om aftenen = in the evening
• om natten = at night

So the definite form morgenen is normal here. It is not saying the morning in a strongly specific English sense; it is just the standard Danish expression.

Because Danish, like English, often uses the present tense for habitual actions.

So tænder hun and lægger can describe something she does regularly:

• Om morgenen tænder hun bruseren...
  = In the morning, she turns on the shower...

This can mean a general habit, not just something happening right now.

The verb at tænde often means to turn on, not only to light.

So it can be used for things like:

• tænde lyset = turn on the light
• tænde radioen = turn on the radio
• tænde bruseren = turn on the shower

In this sentence, tænder hun bruseren means she turns the shower on.

That -en ending marks the definite singular form for many common-gender nouns in Danish.

So:

• en bruser = a shower

• bruseren = the shower

• en håndvask = a sink
• håndvasken = the sink

Unlike English, Danish usually adds the definite article to the end of the noun instead of putting a separate word before it.

Because sin is the reflexive possessive, used when the owner is the same as the subject of the clause.

Here, the subject is hun, and the toothbrush belongs to her, so Danish uses sin:

• hun lægger sin tandbørste...

If you said hendes tandbørste, it would normally suggest someone else’s toothbrush, not the subject’s own.

Also note the forms:

• sin for common-gender singular nouns
• sit for neuter singular nouns
• sine for plural nouns

Because when a noun has a possessive like sin, min, din, hans, or hendes, Danish normally does not use an article as well.

So:

• sin tandbørste = her own toothbrush
• not sin en tandbørste
• not sin tandbørsten

This is similar to English, where we say her toothbrush, not the her toothbrush.

Ved usually means by, near, or next to.

So ved håndvasken means that she places the toothbrush by the sink or near the sink.

This is different from:

• i håndvasken = in the sink
• på håndvasken = on the sink

So ved is about location nearby, not necessarily inside or on top of it.

Because the sentence can keep the same subject for both verbs:

• Om morgenen tænder hun bruseren og lægger sin tandbørste ved håndvasken.

Here, hun is the subject of both tænder and lægger.

You could also say:

• Om morgenen tænder hun bruseren, og hun lægger sin tandbørste ved håndvasken.

That is also grammatical, but it is less compact. The original version is very natural.

At lægge means to lay or to put down, often with the idea that something ends up lying flat or simply being placed somewhere.

That works well with tandbørste, because a toothbrush is often placed down on a surface.

Danish also has related verbs:

• stille = place something standing upright
• sætte = set/place something in a seated or attached position
• lægge = lay/place something down

So lægger sin tandbørste is a natural choice here.

In everyday Danish, håndvask commonly means a washbasin or sink, especially in a bathroom context.

Because this sentence also mentions bruseren and tandbørste, the bathroom meaning is very clear.

In a kitchen, Danish can also use other words depending on context, but håndvasken here clearly refers to the bathroom sink.
