Hun har det ikke med at klage, men i dag siger hun, at mødet var alt for langt.

Har det med at is an idiomatic expression meaning to tend to or to have a habit of doing something.

So:

• Hun har det med at klage = She tends to complain
• Hun har det ikke med at klage = She doesn’t tend to complain

It is more natural and idiomatic than translating word by word.

In this expression, det is part of a fixed idiom. It does not have a strong independent meaning here.

So you should learn have det med at + infinitive as one whole pattern:

• jeg har det med at glemme ting = I tend to forget things
• hun har det ikke med at klage = she doesn’t tend to complain

A learner often wants to translate det directly as it, but in this expression that does not work well. It is just part of the structure.

Because after have det med at, Danish normally uses at + infinitive.

So the pattern is:

• have det med at sige
• have det med at glemme
• have det med at klage

This is similar to English structures like to tend to complain, where another verb follows the main phrase.

In a normal Danish main clause, the finite verb usually comes early, and ikke often appears after that verb and after certain sentence elements.

Here:

• Hun = subject
• har = finite verb
• det = part of the idiom
• ikke = negation

So Hun har det ikke med at klage is the natural word order.

You should think of ikke as negating the whole tendency: she is not the kind of person who usually complains.

Danish main clauses follow the V2 rule, meaning the finite verb usually comes in the second position.

When the sentence begins with i dag, that counts as the first element, so the verb must come next:

• I dag siger hun ...

This causes hun to come after the verb.

Compare:

• Hun siger i dag, at ...
• I dag siger hun, at ...

Both are possible, but the second version puts more focus on today.

Men means but. It connects two contrasting ideas:

• She does not usually complain
• But today she does complain about something

So the contrast is important: her behavior today is unusual for her.

Mødet is the definite form of møde, meaning the meeting.

In Danish, definiteness is often shown by adding an ending to the noun:

• et møde = a meeting
• mødet = the meeting

So here the speaker is referring to a specific meeting that both speaker and listener can identify.

Var is the past tense of er.

It is used here because the meeting is understood as a completed event in the past. She says today that the meeting was too long.

So the timing is:

• siger = present, what she says now
• var = past, describing the meeting that already happened

English does something very similar:

• She says that the meeting was too long

Alt for means far too or much too.

So:

• for langt = too long
• alt for langt = far too long

It strengthens the complaint. It is more emphatic than just saying the meeting was a little too long.

Examples:

• Det er alt for dyrt = It is far too expensive
• Bogen er alt for svær = The book is far too difficult

Because langt is the t-form of the adjective lang.

The noun mødet comes from et møde, and nouns with et often take the -t form of the adjective when the adjective is used predicatively:

• en dag er lang
• et møde er langt

So:

• dagen var lang
• mødet var langt

That is why the sentence says mødet var alt for langt.

The part at mødet var alt for langt is a subordinate clause: that the meeting was far too long.

Danish often uses a comma before subordinate clauses, especially in standard written Danish.

So:

• hun siger, at mødet var alt for langt

The comma helps show that the second part depends on siger.

Yes. It is very normal.

Sige at ... means to say that ...:

• Han siger, at han kommer = He says that he is coming
• Hun siger, at mødet var alt for langt = She says that the meeting was far too long

In everyday speech, Danish sometimes drops at, just as English sometimes drops that, but with a full learner sentence like this, keeping at is very natural and clear.

No. It usually means she doesn’t usually complain or is not the type to complain.

That is softer than saying she never complains.

So the sentence suggests:

• complaining is not normal for her
• today is an exception

That makes the second half stronger: if even she says the meeting was too long, it probably really was too long.
