Leieavtalen er klar.

It is a compound noun:

• leie = rent, rental, hiring
• avtale = agreement

Together, leieavtale means rental agreement or lease agreement.

Then the noun is made definite, so leieavtalen means the rental agreement.

In Norwegian, the definite article is usually attached to the end of the noun instead of being a separate word.

So:

• en leieavtale = a rental agreement
• leieavtalen = the rental agreement

That is why Norwegian does not need a separate the here.

In Norwegian compounds, the last part is the main noun, and that is the part that carries the grammatical ending.

So:

• leieavtale = rental agreement
• leieavtalen = the rental agreement

The first part, leie-, stays the same. This is very common in Norwegian compound nouns.

Er is the present tense of å være, which means to be.

So:

• Leieavtalen er klar = The rental agreement is ready

If you changed the tense, you would get things like:

• Leieavtalen var klar = The rental agreement was ready
• Leieavtalen blir klar = The rental agreement is becoming ready / will be ready

Norwegian adjectives often agree with the noun.

With klar, the usual pattern is:

• klar for singular non-neuter nouns
• klart for singular neuter nouns
• klare for plural

So:

• Leieavtalen er klar
• Huset er klart = The house is ready
• Dokumentene er klare = The documents are ready

Here, leieavtalen is singular and not neuter, so klar is the correct form.

It can mean either ready or clear, depending on context.

In Leieavtalen er klar, it normally means ready. The idea is that the rental agreement has been prepared and is now ready to sign, send, or use.

In other contexts, klar can mean clear or obvious.

This is a normal Norwegian main clause with the basic order:

subject + verb + complement

So:

• Leieavtalen = subject
• er = verb
• klar = complement

This is the standard way to make a simple statement in Norwegian.

A rough English-style guide would be:

• Leieavtalen ≈ LYE-eh-av-TAH-len
• er ≈ ehr
• klar ≈ klahr

A few helpful notes:

• ei in leie sounds roughly like the vowel in eye
• a in klar is long and open
• pronunciation varies by dialect, so you may hear small differences

Because Norwegian does not capitalize ordinary nouns.

Only the first word of the sentence and proper nouns get capitals. So:

• Leieavtalen er klar. is correct
• not every noun is capitalized the way it is in German

That is a common difference for learners who know German or have seen other Germanic languages.
