Hun opdaterer sit cv, før hun sender det til firmaet.

Because sit is the reflexive possessive form. It is used when the possessor is the subject of the same clause.

In Hun opdaterer sit cv:

• Hun = the subject
• sit cv = her own CV

So sit shows that she is updating her own CV.

Compare:

• Hun opdaterer sit cv = She updates her own CV.
• Hun opdaterer hendes cv = She updates another woman’s CV.

Also, sit is used here because cv is treated as a neuter singular noun. The reflexive possessive forms are:

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

So:

• sin bil = his/her own car
• sit cv = his/her own CV
• sine papirer = his/her own papers

Det refers back to cv.

In Danish, pronouns must match the grammatical gender and number of the noun they replace. Since cv is normally treated as a neuter singular noun (et cv), the correct pronoun is det.

So:

• et cv
• cv’et
• det

That is why the sentence says:

• før hun sender det til firmaet

not den.

Because Danish usually adds the definite article to the end of the noun.

So:

• et firma = a company
• firmaet = the company

This is one of the biggest differences from English. Instead of a separate word like the, Danish often attaches definiteness directly to the noun.

Examples:

• en bil = a car

• bilen = the car

• et hus = a house

• huset = the house

• et firma = a company
• firmaet = the company

Because før means before, while for is a completely different word.

• før = before
• for = for, too, too much, because of, etc., depending on context

So in this sentence, only før makes sense:

• før hun sender det = before she sends it

The letter ø matters. It changes both the spelling and the meaning.

No. After før, you get a subordinate clause, and subordinate clauses in Danish normally keep the order:

• subject + verb + other elements

So:

• før hun sender det

This is normal subordinate clause word order.

Compare with a main clause:

• Hun sender det til firmaet.

If another element is moved to the front in a main clause, Danish usually has inversion:

• Nu sender hun det til firmaet.

But after a subordinating conjunction like før, at, fordi, hvis, når, you do not use that kind of inversion:

• før hun sender det
• fordi hun sender det
• hvis hun sender det

Because Danish needs a full clause after før here.

So før hun sender det literally means:

• before she sends it

Danish normally requires the subject to be expressed in that clause. English can sometimes shorten things, for example:

• before sending it

But Danish much more naturally uses the full clause:

• før hun sender det

Both are present tense forms.

• opdaterer = updates / is updating
• sender = sends / is sending

In Danish, the present tense is used quite broadly. Depending on context, it can express:

• a general/habitual action
• something happening now
• a near-future or planned action

So this sentence could describe:

• a routine: she updates her CV before sending it
• what she is doing now
• a planned next step

Danish often uses the present tense where English might choose either simple present or present progressive.

Because før hun sender det til firmaet is a subordinate clause.

In Danish, many writers place a comma before a subordinate clause, as in:

• Hun opdaterer sit cv, før hun sender det til firmaet.

You should know, though, that Danish comma usage has some variation depending on the comma system being followed. So you may also see:

• Hun opdaterer sit cv før hun sender det til firmaet.

Both can occur, but the version with the comma is very common and clear for learners.

Because the verb sende often takes a destination introduced by til when you are saying where something is being sent.

So:

• sende det til firmaet = send it to the company

Here:

• det = the thing being sent
• til firmaet = the destination

Without til, the meaning and structure would be different.

Yes, you may see both cv and CV.

This word is borrowed from another language and is an abbreviation, so capitalization can vary in real usage. In modern Danish, cv in lowercase is very common, especially in ordinary running text, but CV is also seen.

Grammatically, it behaves like a noun:

• et cv
• cv’et
• mit cv
• sit cv

So even though it is an abbreviation, it still fits into normal Danish grammar.

You can say it grammatically, but it usually means something different.

• Hun opdaterer sit cv = She updates her own CV.
• Hun opdaterer hendes cv = She updates another woman’s CV.

So in this sentence, sit is the natural choice because the woman is updating her own CV before sending it.

This difference is very important in Danish, because Danish distinguishes clearly between:

• reflexive possession: sin/sit/sine
• non-reflexive possession: hans/hendes/deres

Because cv is a neuter noun.

The choice between sin, sit, and sine depends on the noun being possessed, not on the person who owns it.

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

Examples:

• Hun vasker sin bil.
• Hun opdaterer sit cv.
• Hun finder sine papirer.

So the form changes to match cv, which is et cv.

Yes, firmaet means the company, so it refers to a specific company that is known from the context.

If you wanted to mean a company, you would say:

• et firma

So:

• til firmaet = to the company
• til et firma = to a company

The sentence as written suggests she is sending it to a particular company, not just any company.
