Hun glemte at vedhæfte filen, så hendes chef bad om den igen.

Glemte is the simple past of glemme (to forget).

A few useful forms:

• glemme = to forget
• glemmer = forgets / is forgetting
• glemte = forgot
• glemt = forgotten

So Hun glemte at vedhæfte filen means She forgot to attach the file.

Because at is the normal infinitive marker in Danish, like to in English.

After verbs such as glemme (forget), Danish usually uses:

• glemme at + infinitive

So:

• glemte at vedhæfte = forgot to attach
• huskede at sende = remembered to send
• forsøgte at ringe = tried to call

Vedhæfte means to attach, especially in contexts like email attachments, files, or documents.

So in this sentence:

• vedhæfte filen = attach the file

It is a very natural verb in office or email language.

Related ideas:

• en vedhæftet fil = an attached file / attachment
• at sende en fil = to send a file
• at vedhæfte en fil = to attach a file

Because Danish usually puts the definite article at the end of the noun.

So:

• en fil = a file
• filen = the file

This is one of the big differences from English.

More examples:

• en chef = a boss
• chefen = the boss
• en e-mail = an email
• e-mailen = the email

This is a very common question.

Danish uses sin/sit/sine for a reflexive possessor, meaning the possession belongs to the subject of the same clause.

Here, in the second clause:

• hendes chef bad om den igen

the subject is chefen (the boss), not hun.

So if you said sin chef, it would refer back to the subject of that clause, which would create the wrong meaning. It could sound like the boss’s own boss rather than her boss.

So:

• hendes chef = her boss
• sin chef would not work here for her boss

A useful comparison:

• Hun talte med sin chef. = She spoke with her own boss.
  Here hun is the subject, so sin works.
• Hendes chef ringede. = Her boss called.
  Here the subject is chef, so you use hendes, not sin.

Here så means so, therefore, or as a result.

It connects the two ideas:

• She forgot to attach the file,
• so her boss asked for it again.

In this sentence, så is a coordinating conjunction linking two main clauses.

Because the sentence contains two main clauses:

1. Hun glemte at vedhæfte filen
2. så hendes chef bad om den igen

In standard Danish punctuation, a comma is commonly used to separate clauses like this.

So the comma helps show the structure:

• first event
• result/consequence

Bad is the past tense of bede (to ask / to request), and bede om means to ask for something.

So:

• bede om noget = ask for something
• bad om den = asked for it

Useful forms:

• bede om = to ask for
• beder om = asks for
• bad om = asked for
• bedt om = asked for

This is an important pattern:

• Hun bad om hjælp. = She asked for help.
• Han bad om filen. = He asked for the file.

Because Danish uses the fixed expression bede om for ask for/request.

English says:

• ask for the file

Danish says:

• bede om filen

So the om is not optional here. It belongs to the verb pattern.

Compare:

• Han bad om vand. = He asked for water.
• Chefen bad om rapporten. = The boss asked for the report.

Because fil is an en-word in Danish:

• en fil

When you refer back to an en-word, you usually use den:

• filen → den

If the noun were a et-word, you would use det instead.

Examples:

• en fil → den
• et dokument → det

So:

• bad om den igen = asked for it again
  because it refers to filen.

Yes, the sentence leaves out the person being asked, because it is obvious from context.

A fuller version could be:

• hendes chef bad hende om den igen
  = her boss asked her for it again

But Danish often omits that part if it is already clear who the boss asked.

So the shorter sentence is natural and efficient.

Because that is the most natural position here for igen (again).

The phrase:

• bad om den igen

means:

• asked for it again

In Danish, short object pronouns such as den often come before adverbs like igen, so the end position sounds very natural.

Compare:

• Han gjorde det igen. = He did it again.
• Hun sendte den igen. = She sent it again.

After så used as a conjunction meaning so, Danish keeps normal main clause word order:

• så hendes chef bad om den igen

That is:

• så
  • subject + verb

So:

• hendes chef = subject
• bad = verb

This is different from cases where another element is moved to the front and causes inversion.

For example:

• Derfor bad hendes chef om den igen. = Therefore, her boss asked for it again.

Here derfor is first, so the verb comes before the subject:

• Derfor bad hendes chef...

But with conjunction så here, you get:

• så hendes chef bad...

No. In Danish, chef means boss/manager, not the English cook meaning.

It is pronounced more like:

• shef

So in this sentence, chef means:

• boss
• manager
• supervisor depending on context

That often surprises English speakers because the spelling looks familiar but the meaning is different.
