Jeg tager et billede af whiteboardet, før hun sender sin præsentation til os.

In Danish, the present tense is very often used for future actions when the context makes the time clear.

So Jeg tager et billede ... før hun sender ... can mean something like:

• I take/am taking a picture ...
• I’ll take a picture ...

The word før already shows the time relationship, so Danish does not need a special future form here.

Tager is the present tense of tage, which means to take.

A very common pattern in Danish is:

• infinitive: tage
• present tense: tager

That -r ending is the normal present-tense ending for many Danish verbs.

Because billede is a neuter noun in Danish.

Danish nouns are mainly either:

• common gender: take en
• neuter: take et

So:

• et billede = a picture

You simply have to learn the gender with the noun.

Because tage et billede af noget/nogen is the normal Danish expression for take a picture of something/someone.

So:

• et billede af whiteboardet = a picture of the whiteboard

Even though af often means of, here it is just part of the standard Danish structure used with billede.

The -et ending makes the noun definite, so whiteboardet means the whiteboard.

Danish usually adds the definite article to the end of the noun instead of putting a separate word in front:

• et whiteboard = a whiteboard
• whiteboardet = the whiteboard

So there is no separate the word here.

Yes. Danish uses many loanwords from English, and they often take normal Danish endings.

So even though whiteboard comes from English, Danish can still treat it like a regular Danish noun:

• et whiteboard
• whiteboardet

That is very normal.

Because før hun sender sin præsentation til os is a subordinate clause, and many Danes write a comma before subordinate clauses.

However, this is a point where you may see variation. In modern Danish, many writers also omit that comma in this kind of sentence.

So both styles may be seen, depending on the comma system being used.

Because før introduces a subordinate clause.

In a main clause, Danish often has verb-second word order, but subordinate clauses do not work the same way. After før, the normal order is:

• hun sender

So the subject hun comes before the verb sender.

Because sin is the reflexive possessive form, and it is used when the possession belongs to the subject of the same clause.

In før hun sender sin præsentation til os, the subject of that clause is hun, so sin præsentation means her own presentation.

If you said hendes præsentation, it would usually suggest someone else’s presentation, not the subject’s own.

Also, sin/sit/sine agrees with the thing possessed:

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

Since præsentation is a common-gender singular noun, sin is the correct form.

Danish often uses til to mark the recipient:

• sende noget til nogen = send something to someone

So:

• sender sin præsentation til os = sends her presentation to us

You can also say:

• hun sender os sin præsentation

That is also correct. The version with til os is just another normal way to express the recipient.
