Bildet er utvalgt.

Because bilde is the indefinite form: a picture / an image.

Norwegian usually adds the definite article to the end of the noun instead of using a separate word like the. Since bilde is a neuter noun (et bilde), its definite singular form is bildet = the picture / the image.

Useful pattern:

• et bilde = a picture
• bildet = the picture
• bilder = pictures
• bildene = the pictures

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

So in Bildet er utvalgt, er links the subject (bildet) with the description/result (utvalgt).

Very literally, the structure is:

• Bildet = the picture
• er = is
• utvalgt = selected / chosen

Utvalgt is a past participle, and in this sentence it functions much like an adjective.

That means it describes the state or result affecting the picture: the picture is in a selected/chosen state.

This is very common in Norwegian:

• Døren er lukket = The door is closed
• Boken er skrevet = The book is written / has been written
• Bildet er utvalgt = The picture is selected / has been selected

So even though utvalgt comes from a verb, here it behaves like a descriptive word.

Because predicate adjectives/participles in Norwegian do not take the definite -e form just because the noun is definite.

Compare:

• det utvalgte bildet = the selected picture
  Here the word comes before the noun, so it takes the definite form utvalgte.

But:

• Bildet er utvalgt = The picture is selected
  Here it comes after er, so it stays in the predicate form utvalgt.

This is a very important pattern in Norwegian:

• den røde bilen = the red car
• Bilen er rød = The car is red

So bildet being definite does not force utvalgt to become utvalgte in this sentence.

It can suggest either one, depending on context.

In practice, er + past participle often expresses a resulting state:

• The picture is selected
• The picture has been selected

In English, those are slightly different, but Norwegian often allows the same form to cover both ideas.

If you want to focus more clearly on the event in the past, Norwegian can also use ble:

• Bildet ble utvalgt = The picture was selected

So a simple contrast is:

• er utvalgt = focuses on the current result/state
• ble utvalgt = focuses on the action/event

It is related to the idea to select / choose out.

A learner will often meet related forms such as:

• å velge = to choose
• å velge ut = to select / choose out
• utvalgt = selected / chosen

So utvalgt is not a random form you just have to memorize in isolation; it belongs to the same word family as velge.

A useful thing to notice is that Norwegian often has verbs and participles that do not look completely regular, so this is a form worth learning as a chunk:

• velge
• valgt
• utvalgt

Yes. That would also be correct, but it means something slightly different in emphasis.

• Bildet er utvalgt = the picture is selected / has been selected
  Focus: the current state or result

• Bildet ble utvalgt = the picture was selected
  Focus: the event happened

So if you are describing the present situation, er utvalgt is natural. If you are telling what happened at a particular time in the past, ble utvalgt is often better.

No, this is the normal basic word order for a simple statement in Norwegian:

• Subject + verb + complement

So:

• Bildet = subject
• er = verb
• utvalgt = complement

This is the same general pattern as in English:

• The picture is selected

So the sentence is very straightforward in word order.
