Hun håber at slippe for at arbejde sent på fredag, så hun kan møde os.

They introduce two different infinitives:

• håber at slippe = hopes to avoid/get out of
• for at arbejde = part of the fixed expression slippe for at + infinitive

So the structure is:

• håbe at + infinitive
• slippe for at + infinitive

In English, you could think of it as:

• hope to avoid having to work late

Even though English does not always repeat to, Danish often keeps the infinitive marker at with each infinitive verb.

Slippe for means to avoid, to get out of, or to not have to do something unpleasant or inconvenient.

So:

• slippe for at arbejde sent = avoid working late / not have to work late

This is a very common Danish expression. You will often see:

• Jeg slap for at lave lektier. = I got out of doing homework.
• Vi slap for at vente længe. = We avoided waiting a long time.

It often implies relief.

Because the idiomatic expression is slippe for at + infinitive when the meaning is avoid having to do something.

• slippe for at arbejde sent = avoid having to work late

Using slippe at would not sound natural in this meaning. The for is part of the fixed phrase.

På fredag means on Friday, usually referring to the upcoming Friday in context.

Examples:

• Vi ses på fredag. = See you on Friday.
• Hun arbejder på fredag. = She is working on Friday.

It does not automatically mean every Friday. For repeated events, Danish would use something like:

• om fredagen = on Fridays / on Friday(s) generally

So here på fredag refers to one specific Friday.

In Danish, adverbs like sent usually stay close to the verb or verbal idea they describe.

• arbejde sent på fredag = work late on Friday

That is the natural order:

1. verb (arbejde)
2. manner/time-related adverb (sent)
3. larger time phrase (på fredag)

Putting på fredag before sent is possible in some contexts for emphasis, but the given version is the most neutral and natural here.

Here så means so (that) or so that. It introduces a result or purpose.

• Hun håber at slippe for at arbejde sent på fredag, så hun kan møde os.
• She hopes to avoid working late on Friday so that she can meet us.

So the second clause explains the reason or desired result.

Because så here is acting like a conjunction introducing a subordinate clause.

In Danish subordinate clauses, the subject usually comes before the finite verb:

• så hun kan møde os

Compare:

• Main clause: Hun kan møde os.
• Subordinate clause after conjunction: ... så hun kan møde os.

If you said så kan hun møde os, that would sound more like and then she can meet us in a main-clause structure, not a purpose/result clause.

It can mean either depending on context, but most naturally here it means:

• be able to meet us
• be free to meet us

Because the earlier clause is about her schedule, kan here is about possibility or availability, not physical ability.

So the idea is:

• if she does not have to work late, then she will be able to meet us

Because os is the object form of we/us.

• vi = subject form = we
• os = object form = us

In møde os, os is the object of møde:

• hun kan møde os = she can meet us

Just like in English, you would say meet us, not meet we.

Yes, in Danish møde usually takes a direct object, unlike English meet, which also takes a direct object.

So:

• møde os = meet us
• møde ham = meet him
• møde læreren = meet the teacher

You do not say møde med os for this meaning.
Møde med would suggest have a meeting with in certain contexts, which is different.

In standard written Danish, håber at slippe is the normal form.

In informal speech, some speakers may reduce or blur at, but for learners it is best to keep it:

• Hun håber at slippe ...

That is the safe, standard choice.

Because slippe is an infinitive, not a separate finite clause.

The subject hun belongs to the whole structure:

• Hun håber at slippe ...

This works like English:

• She hopes to avoid ...

You do not say:

• She hopes she to avoid ...

Likewise in Danish, hun is stated once, and slippe stays in the infinitive.

No. Håber shows hope, not certainty.

• Hun håber ... = She hopes ...
• It suggests that the situation is not decided yet.

She wants to avoid working late, but we do not know whether that will actually happen.

Not with the same meaning.

• så hun kan møde os = so that she can meet us / expressing purpose or result
• fordi hun kan møde os = because she can meet us / expressing cause

Those are different ideas.

Here, the intended meaning is:

• she hopes to avoid working late in order to be able to meet us

So så is the right choice.

It is not a completely fixed idiom, but it is a very common and natural combination.

• arbejde sent = work late
• komme sent = arrive late
• være sent på den = be late

Here sent is simply the adverb late, describing when the work happens.

A useful breakdown is:

• Hun håber = She hopes
• at slippe for at arbejde sent på fredag = to avoid having to work late on Friday
• så hun kan møde os = so that she can meet us

So the overall structure is:

1. main clause: Hun håber
2. infinitive phrase: at slippe for at arbejde sent på fredag
3. purpose/result clause: så hun kan møde os

This makes it much easier to understand the grammar.
