Oppsigelsen må ha en utflyttingsdato.

Here, oppsigelsen means the notice of termination or simply the notice. In housing contexts, it often refers to a notice ending a rental agreement.

The base noun is en oppsigelse = a termination / a notice of termination.
With the ending -n, it becomes definite: oppsigelsen = the termination / the notice.

Depending on context, a natural English translation could be:

• The notice must have a move-out date.
• The termination notice must include a move-out date.

Because Norwegian often puts the definite article at the end of the noun.

• en oppsigelse = a notice / a termination
• oppsigelsen = the notice / the termination

This is very common in Norwegian:

• en bil → bilen = the car
• en dato → datoen = the date

So -en here works like English the.

Because the sentence is talking about a move-out date, not the move-out date.

• en utflyttingsdato = a move-out date
• utflyttingsdatoen = the move-out date

So the sentence says that the notice must have some move-out date specified, not necessarily one already known to both speaker and listener.

må means must and ha means have.

So må ha literally means must have.

In this sentence, ha can also feel like contain or include in English:

• Oppsigelsen må ha en utflyttingsdato.
• The notice must have / include a move-out date.

That use of ha is very natural in Norwegian.

Because må is a modal verb, and modal verbs in Norwegian are followed by the infinitive without å.

So you say:

• må ha = must have
• kan komme = can come
• vil spise = want to eat / will eat
• skal dra = will / shall leave

Not:

• må å ha ❌

This is similar to English, where we say must have, not must to have.

It is a compound noun, which is extremely common in Norwegian.

It can be broken down like this:

• utflytting = moving out
• dato = date

Together:

• utflyttingsdato = move-out date

The -s- in the middle is a linking sound often used in compounds. It does not always directly translate into anything; it just helps connect the parts.

So this is similar to how English builds nouns like:

• move-out date
• rental contract
• bedroom door

The structure is:

• Oppsigelsen = subject
• må = finite verb
• ha = infinitive
• en utflyttingsdato = object

So the sentence follows the normal Norwegian main-clause order:

Subject + verb + rest

That gives:

Oppsigelsen må ha en utflyttingsdato.

This is very standard and natural word order.

No. Oppsigelse can be used in several kinds of termination contexts.

For example, it can refer to:

• ending a job contract
• canceling or terminating an agreement
• ending a tenancy or lease

So the exact English translation depends on context. In a housing context, oppsigelsen is usually something like:

• the notice
• the notice of termination
• the lease termination notice

Both main nouns here are common-gender nouns introduced with en:

• en oppsigelse
• en dato
• therefore en utflyttingsdato

Because utflyttingsdato ends with dato, and the last part of a Norwegian compound usually determines the grammatical gender, the whole compound is also common gender:

• en utflyttingsdato
• utflyttingsdatoen

Yes, absolutely. That is often one of the most natural English translations.

Literal translation:

• The notice must have a move-out date.

Natural English in context:

• The notice must include a move-out date.

Norwegian often uses ha where English might prefer have, contain, or include, depending on context.

Not exactly.

• må ha = must have
  This expresses necessity or requirement.

• skal ha can mean is supposed to have, is to have, or sometimes will have, depending on context.

In a rule or requirement, må ha is stronger and clearer:

• Oppsigelsen må ha en utflyttingsdato.
  = It is required that the notice include a move-out date.

So må is the better choice if the meaning is a firm requirement.

A few natural options are:

• The notice must include a move-out date.
• The termination notice must include a move-out date.
• The notice has to state a move-out date.

The best choice depends on context, but grammatically they all match the Norwegian sentence well.

A rough pronunciation guide for an English speaker could be:

• oppsigelsen ≈ OP-si-gel-sen
• må ≈ a long vowel somewhat like moh but rounded
• ha ≈ hah
• en ≈ short en
• utflyttingsdato ≈ OOT-flyt-ingz-dah-too

A few important notes:

• å in må is not the same as English o. It is a rounded vowel.
• y in flytting is a front rounded vowel, which many English speakers find difficult.
• Norwegian compounds are usually spoken as one word: utflyttingsdato.

If you want to sound more natural, the biggest challenges here are usually må and the y sound in utflytting.
