Hils derhjemme.

Hils is the imperative form of the verb at hilse.

So the basic pattern is:

• at hilse = to greet / to say hello to
• hils! = greet! / say hello!

In this sentence, the speaker is telling someone to pass on greetings.

In Danish, the object can be left understood when the meaning is obvious from context.

So Hils derhjemme literally looks a bit like Greet at home, but what it really means is more like:

• greet the people at home
• say hello to everyone at home

Danish often leaves this unstated because native speakers automatically understand who is meant.

Derhjemme is an adverb meaning at home, back home, or at your/their home, depending on context.

In this sentence, it refers to the people who are at the listener’s home or back where they live.

So derhjemme does not name a person; it points to a place, and by extension the people there.

Both relate to home, but derhjemme often feels a little more specific: back home / over at home / at home where your people are.

In a phrase like Hils derhjemme, derhjemme is very natural and idiomatic. It suggests:

• the home situation of the person you are talking to
• the people back at their place

Using hjemme here would sound less natural in this fixed expression.

Yes. It is a very common, natural thing to say when ending a conversation with someone whose family, partner, or housemates you know about.

It is similar to saying:

• Say hello to everyone at home
• Give my regards to your family
• Say hi at home

It is friendly and everyday Danish.

It is generally informal to neutral.

You can say it in many everyday situations:

• to a friend
• to a colleague you know reasonably well
• to a relative
• to a neighbor

In a very formal situation, people might choose a fuller phrase, but Hils derhjemme is widely acceptable in normal speech.

Yes. Very often you will hear:

• Hils derhjemme fra mig

That means Say hello to everyone at home from me.

Adding fra mig makes it explicit that the greetings come from you. Without it, that idea is often still understood from context.

A rough guide is:

• Hils ≈ heels but shorter and crisper
• derhjemme ≈ dehr-YEM-uh

A more important thing than perfect sound-by-sound pronunciation is the rhythm:

• HILS der-HJEM-me

The main stress falls on hjem in derhjemme.

Usually Hils derhjemme is broad and general: it means the people at home as a group.

If you want to greet one specific person, Danish normally says so directly, for example:

• Hils din mor
• Hils din far
• Hils Peter

So Hils derhjemme is best when you mean everyone at home rather than one named person.

The sentence is very simple:

• Hils = imperative verb
• derhjemme = adverb

Imperatives in Danish often begin directly with the verb, just as in English:

• Come here
• Sit down
• Hils derhjemme

There is no subject written, because the subject is understood as you. So the full sense is:

• (You) greet everyone at home
