Hvor hyggeligt at se dig igen!

In this sentence, hvor means how, not where.

So Hvor hyggeligt! means How nice/cozy!

This is a common Danish pattern in exclamations:

• Hvor flot! = How beautiful!
• Hvor dejligt! = How lovely!
• Hvor spændende! = How exciting!

So here hvor introduces an emotional reaction.

Hyggeligt is the neuter singular form of the adjective hyggelig.

In this kind of exclamation, Danish often uses the neuter form because the adjective is being used in a general way, similar to English How nice! rather than describing a specific common-gender noun.

Compare:

• en hyggelig café = a cozy café
• et hyggeligt sted = a cozy place
• Hvor hyggeligt! = How nice/cozy!

So hyggeligt is the natural form in this expression.

Danish often allows short exclamations without an explicit verb, just like English:

• How lovely to see you again!
• How nice!

So Hvor hyggeligt at se dig igen! is a perfectly normal exclamatory phrase. A fuller version could be something like:

• Det er hyggeligt at se dig igen. = It is nice to see you again.

But in spontaneous speech, the shorter exclamation sounds warmer and more natural.

At se dig igen is an infinitive phrase meaning to see you again.

It explains what is nice:

• Hvor hyggeligt = How nice
• at se dig igen = to see you again

So the structure is basically:

• How nice + to see you again

This is very similar to English grammar.

Because dig is the object form of you, while du is the subject form.

• du = you, as the subject
• dig = you, as the object

In at se dig, you is the object of to see, so Danish uses dig.

Compare:

• Du er her. = You are here.
• Jeg ser dig. = I see you.

Here igen means again, and it naturally comes after dig:

• at se dig igen = to see you again

This is the most normal word order.

You may sometimes see adverbs move in other sentence types, but in this infinitive phrase, at se dig igen is the standard and idiomatic order.

Not really. Although hyggelig/hyggeligt often gets translated as cozy, in this sentence that can sound too literal in English.

Here it is better understood as something like:

• nice
• lovely
• pleasant
• so nice

So Hvor hyggeligt at se dig igen! is more like How lovely to see you again! than How cozy to see you again!

This is a good example of how hyggelig can describe a warm, pleasant social feeling, not just physical coziness.

It is friendly and natural, and it works well in both informal and moderately polite situations.

The sentence uses dig, which is the ordinary singular you, so it is directed at one person in the normal modern Danish way. Since modern Danish generally uses the informal du-form in most situations, this sentence is appropriate with friends, family, colleagues, and many everyday encounters.

It sounds warm and personal.

Yes, absolutely. It sounds natural and idiomatic.

A Dane might say it when meeting someone again after some time, especially in a warm or friendly context. Depending on tone and personality, you might also hear similar expressions such as:

• Hvor dejligt at se dig igen! = How lovely to see you again!
• Det er hyggeligt at se dig igen. = It’s nice to see you again.

Your sentence is very natural as an enthusiastic greeting.

A rough learner-friendly guide is:

vor HOO-guh-leet at see die i-GEN

A few notes:

• Hvor sounds roughly like vor
• hyggeligt is tricky; the y sound does not exist in English, and the word is often pronounced quite softly
• dig in connected speech may sound softer than you expect
• igen has stress on the second syllable: i-GEN

If you want to sound natural, the most important thing is the warm, enthusiastic intonation of the whole sentence.
