Hun overtalte medlåntakeren.

Hun is the third-person singular pronoun she.

A few useful notes:

• It is used for a female person.
• In Norwegian, pronouns are only capitalized at the start of a sentence, so Hun here is capitalized because it comes first.

Because overtalte is the past tense of the verb å overtale, meaning to persuade.

So:

• å overtale = to persuade
• overtaler = persuades / is persuading
• overtalte = persuaded

The -te ending is a common past-tense ending for many Norwegian verbs.

The base form is å overtale.

This is the infinitive form, the one you would find in a dictionary. In Norwegian, infinitives usually include å before the verb, similar to English to:

• å spise = to eat
• å skrive = to write
• å overtale = to persuade

Medlåntakeren is a noun in the definite singular form.

It can be broken down like this:

• med- = co- / with
• låntaker = borrower
• -en = the

So:

• medlåntaker = co-borrower
• medlåntakeren = the co-borrower

This is very typical in Norwegian: words are often built by combining smaller parts into one compound noun.

Because Norwegian usually marks definiteness by adding an ending to the noun.

Compare:

• en medlåntaker = a co-borrower
• medlåntakeren = the co-borrower

This is one of the biggest differences from English. Instead of putting the before the noun, Norwegian often adds a definite ending:

• en bil = a car
• bilen = the car

This is the normal Norwegian word order for a simple main clause:

subject + verb + object

So here:

• Hun = subject
• overtalte = verb
• medlåntakeren = object

This is the same basic order as in English:

• She persuaded the co-borrower.

Norwegian main clauses also follow the verb-second rule, and this sentence fits that pattern perfectly because the subject comes first and the verb comes second.

In the present tense, it would be:

Hun overtaler medlåntakeren.

That means She persuades or She is persuading the co-borrower, depending on context.

Compare:

• Hun overtaler medlåntakeren. = present
• Hun overtalte medlåntakeren. = past

A rough English-friendly guide would be:

• Hun ≈ hoon (with a rounded vowel, not exactly like English hoon)
• overtalte ≈ OH-ver-tal-te
• medlåntakeren ≈ MED-loan-ta-ke-ren

A few pronunciation notes:

• å in låntaker sounds roughly like the vowel in British law
• the stress in compounds often falls strongly on the first part, so MED-låntakeren
• Norwegian pronunciation varies somewhat by dialect, so exact sound can differ

In Bokmål, medlåntaker is commonly treated as a masculine noun, which is why you see:

• en medlåntaker
• medlåntakeren

In practice, many job/person nouns in Bokmål use en and -en regardless of the actual gender of the person being talked about.

So grammatical gender here is about the noun form, not necessarily the real-life sex of the person.

Yes, but the meaning changes.

• Hun overtalte medlåntakeren. = She persuaded the co-borrower.
• Hun overtalte en medlåntaker. = She persuaded a co-borrower.

So the original sentence refers to a specific co-borrower already known from context, while en medlåntaker would introduce one that is not specifically identified.

Yes, this sentence is standard Bokmål.

A possible Nynorsk version would be:

• Ho overtalte medlåntakaren.

Differences:

• Hun → Ho
• medlåntakeren → medlåntakaren

The verb overtalte can stay the same. For a beginner, it is usually enough just to recognize that the given sentence is perfectly normal Bokmål.
