Legen ser arret.

Because Norwegian usually puts the definite article on the end of the noun.

• en lege = a doctor
• legen = the doctor

So -en here works like English the.
The noun lege is a common gender noun, which is why its definite singular form ends in -en.

For the same reason: it is the definite singular form of the noun.

• et arr = a scar
• arret = the scar

Here, arr is a neuter noun, so the definite ending is typically -et.

The double r is not an extra ending. It is already part of the word arr, and then -et gets added:

• arr
  • -et = arret

Ser is the present tense of å se (to see).

So:

• å se = to see
• ser = see / sees / am seeing / is seeing, depending on context

A very important point for English speakers: Norwegian verbs do not change for person.

• jeg ser = I see
• du ser = you see
• han ser = he sees
• vi ser = we see

It is always ser in the present tense.

Yes. This sentence follows the basic pattern:

subject + verb + object

• Legen = subject
• ser = verb
• arret = object

So Legen ser arret matches English The doctor sees the scar very closely.

However, Norwegian has a strong verb-second rule in main clauses. That means if you move something else to the front, the verb still stays in second position:

• I dag ser legen arret. = Today, the doctor sees the scar.

So the simple sentence looks English-like, but the wider word-order system is not always the same.

Because in Norwegian, the is often built into the noun as an ending instead of being a separate word.

In this sentence:

• legen = the doctor
• arret = the scar

That is one of the first big differences English speakers notice.

But separate words like den, det, and de do appear, especially when an adjective is added:

• legen = the doctor

• den flinke legen = the skilled doctor

• arret = the scar
• det store arret = the big scar

So Norwegian can use both a separate article and a noun ending together when adjectives are involved.

That would be:

En lege ser et arr.

Here:

• en lege = a doctor
• et arr = a scar

So the sentence changes from definite to indefinite like this:

• Legen ser arret. = The doctor sees the scar.
• En lege ser et arr. = A doctor sees a scar.

This also shows the gender difference:

• en for lege
• et for arr

It is not related to the English word leg.

Lege means doctor, and legen means the doctor.

A rough English-friendly pronunciation is:

• legen ≈ LAY-gen
• with a hard g, not like English j

A more important point than the exact accent is this: do not read legen as if it were the English word leg with -en added. It is a completely different word.

Not always. In many varieties of Norwegian, the ending -et is pronounced very lightly, and the final t may be weak or not clearly heard.

So arret may sound closer to:

• AR-re or
• AR-ret

depending on dialect and speaking style.

For a learner, the key thing is to recognize that the spelling -et marks the definite neuter form, even if the pronunciation is reduced in natural speech.
