Plagget er flekkete.

Because plagget is the definite singular form.

• et plagg = a garment / an item of clothing
• plagget = the garment / the item of clothing

Plagg is a neuter noun, so its definite singular ending is -et.

Yes, but it is a bit more general and sometimes slightly more formal than the most natural everyday choice.

Native speakers often use:

• skjorta = the shirt
• buksa = the trousers/pants
• jakka = the jacket

They use plagg when they want to refer to a clothing item in a more general way, especially in:

• shops
• fashion
• laundry/care instructions
• descriptions where the exact type of clothing is not important

So Plagget er flekkete is correct, but in real life a speaker might often say something more specific if they know what the item is.

In Norwegian, the is often built into the noun as an ending.

So:

• et plagg = a garment
• plagget = the garment

English uses a separate article, but Norwegian very often uses a suffix instead.

A very useful thing to remember is:

• indefinite: et plagg
• definite: plagget

Er is the present tense of å være = to be.

So:

• jeg er = I am
• du er = you are
• det er = it is
• plagget er = the garment is

This sentence is just a basic description:

• subject: Plagget
• verb: er
• description: flekkete

So the structure is very similar to English: The garment is stained.

Flekkete is the adjective meaning stained / spotty / covered in spots or stains.

A key grammar point is that adjectives ending in -e often do not change much for gender or number. So you get:

• en flekkete skjorte
• et flekkete plagg
• flekkete klær

And after er, it also stays:

• Skjorta er flekkete
• Plagget er flekkete
• Klærne er flekkete

So here, flekkete is simply the correct adjective form.

It can mean both, depending on context.

Common shades of meaning include:

• stained
• spotty
• marked with spots/blotches

With clothing, flekkete often suggests something undesirable, like stains or dirty marks.

If you mean a deliberate pattern, Norwegian may use a more specific word, for example:

• prikkete = dotted / polka-dotted
• mønstret = patterned

So in Plagget er flekkete, the most natural interpretation is usually that the garment has stains or visible blotches.

Yes.

After the noun, it is predicative:

• Plagget er flekkete.

Before the noun, it is attributive:

• et flekkete plagg
• det flekkete plagget

Notice the last example:

• det flekkete plagget

When a noun is definite and has an adjective before it, Norwegian usually uses both:

1. a definite article: det
2. the noun’s definite ending: -et

That is a very common pattern in Norwegian.

They certainly could say it, and it is perfectly correct. But in everyday speech, people often prefer:

• a more specific noun if they know the item
• a more common general word if talking about clothes in general

For example:

• Skjorta er flekkete. = The shirt is stained.
• Buksa er flekkete. = The trousers/pants are stained.
• Klærne er flekkete. = The clothes are stained.

So plagget is natural when the exact type of clothing is unknown, unimportant, or being discussed in a general way.

A simple approximation is:

PLAHG-get er FLEK-ke-te

A few helpful notes:

• plagget has stress on the first syllable: PLAG-get
• flekkete also has stress on the first syllable: FLEK-ke-te
• the gg in plagg makes the vowel short
• er is often pronounced quite lightly in normal speech

You do not need to pronounce it exactly like English spelling suggests; just aim for clear stress on the first syllable of plagget and flekkete.

The sentence follows a very common Norwegian pattern:

subject + verb + adjective

So:

• Plagget = subject
• er = verb
• flekkete = adjective/complement

This is the normal, neutral word order for a simple statement. It matches English quite closely:

• The garment is stained.

That makes this sentence a good example of a basic descriptive sentence in Norwegian.
