Forkleet er rent.

Because Norwegian usually puts the definite article at the end of the noun instead of using a separate word like the.

• forkle = an apron / apron
• forkleet = the apron

So in this sentence, forkleet is the definite singular form.

The base form is forkle, which means apron.

In dictionary form, you would normally look up the noun as:

• et forkle = an apron

Then the definite singular becomes:

• forkleet = the apron

In Norwegian, definiteness is often built into the noun itself by adding an ending.

English:

• the apron

Norwegian:

• forkleet

This is one of the biggest differences from English. Instead of writing a separate article before the noun, Norwegian often uses a suffix.

Because the adjective has to agree with the noun.

Forkle is a neuter noun, and when an adjective describes a neuter singular noun, the adjective often gets -t.

Here, the adjective is ren = clean.

Its forms include:

• ren for common gender singular
• rent for neuter singular
• rene for plural and many definite uses

So:

• en ren bil = a clean car
• et rent forkle = a clean apron
• Forkleet er rent = The apron is clean

Yes. In Norwegian, adjectives often still agree with the noun even when they come after to be (er).

So although English says:

• The apron is clean

and clean never changes, Norwegian says:

• Forkleet er rent

because rent must match the neuter noun forkleet.

This is called predicate adjective agreement.

Forkle is a neuter noun.

That is why you say:

• et forkle = an apron
• forkleet = the apron
• rent = clean in the neuter singular form

If it were not neuter, the forms would be different.

The word order is very straightforward:

• Forkleet = subject
• er = verb
• rent = adjective/complement

So the structure is:

Subject + verb + adjective

This matches English quite closely:

• The apron is clean
• Forkleet er rent

The indefinite version would be:

• Et forkle er rent.

That means An apron is clean or A(n) apron is clean, depending on context.

Compare:

• et forkle = an apron
• forkleet = the apron

So the sentence you were given is definite: it refers to a specific apron.

A rough English-friendly guide would be:

• forkleet ≈ FOR-kleh-et
• rent ≈ rent but with a clear short e, not like English rained

A few notes:

• The r is Norwegian, so it may sound different from many English accents.
• The final t in rent is pronounced.
• The two vowels in forkleet can feel a little longer than an English speaker might expect.

If you are learning pronunciation, it is best to listen to native audio, since Norwegian vowel quality is important.

In standard Bokmål, no. The expected form here is rent because forkle is neuter.

• Forkleet er rent = correct
• Forkleet er ren = not standard in this context

Ren would be used with a common-gender singular noun, not a neuter one.
