Padleåren har to åreblader.

Because -en is the definite singular ending for many masculine nouns in Norwegian.

• en padleåre = a paddle
• padleåren = the paddle

So Padleåren har to åreblader literally means The paddle has two paddle blades / The paddle has two blades.

In Norwegian, the is usually added to the end of the noun instead of being a separate word in front.

For example:

• en bil = a car
• bilen = the car

So:

• padleåren = the paddle

This is very common in Norwegian.

Padleåre is a compound noun:

• padle = to paddle
• åre = oar / paddle

Together, padleåre refers to a paddle, especially the kind used in kayaking or canoeing.

Norwegian uses compound nouns very often, so it is normal to see several ideas joined into one word.

Åreblader is the plural indefinite form of åreblad.

Breakdown:

• åre = oar / paddle
• blad = blade

So åreblad means paddle blade or oar blade, and:

• et åreblad = a paddle blade
• åreblader = paddle blades

In the sentence, to åreblader means two paddle blades.

After a number like to (two), Norwegian normally uses the indefinite plural form, not the definite plural.

So:

• to åreblader = two paddle blades
• årebladene = the paddle blades

You would only use årebladene if you specifically meant the blades.

Because numbers already determine the noun.

In English, we also say:

• two blades, not a two blades

Norwegian works the same way:

• to åreblader = two blades

So no article is needed there.

No, it is a very normal Norwegian sentence pattern:

• Padleåren = subject
• har = verb
• to åreblader = object

So it follows the basic pattern:

Subject + verb + object

This is the same basic order as in English:

The paddle + has + two blades

Har means has.

It is the present tense of å ha = to have.

Examples:

• Jeg har = I have
• Hun har = She has
• Padleåren har to åreblader = The paddle has two blades

You usually learn that from the indefinite form with the article:

• en padleåre

That tells you it is commonly treated as a noun that takes en in Bokmål.

Then the definite singular becomes:

• padleåren

For the other noun:

• et åreblad
• årebladet
• åreblader

So åreblad is neuter.

Many neuter nouns in Norwegian form the plural with -er, especially compound nouns like this one.

So:

• et åreblad = a paddle blade
• åreblader = paddle blades

This is something you often just learn together with the noun, because plural patterns are not always fully predictable.

The letter å is a separate Norwegian vowel. It is usually pronounced somewhat like the vowel in English more or law, though the exact sound depends on accent.

So:

• åre
• padleåren

both contain that å sound.

It is important not to confuse å with a, because they are different letters in Norwegian.

Not perfectly word-for-word, because Norwegian compound nouns often sound more natural if simplified in English.

A very literal translation is:

• The paddle has two paddle blades

A more natural English translation is often:

• The paddle has two blades

So the Norwegian is completely normal, even if English may choose a shorter wording.
