Jeg kender betalingsmodtageren slet ikke.

It breaks down like this:

• Jeg = subject
• kender = finite verb, present tense of kende
• betalingsmodtageren = direct object
• slet ikke = emphatic negation, meaning not at all

So the sentence structure is basically:

Subject + verb + object + emphatic negation

Because Danish usually separates these two ideas:

• kende = to know someone or be familiar/acquainted with someone or something
• vide = to know a fact or piece of information

Here, betalingsmodtageren is treated like a person, company, or recipient that the speaker is not familiar with, so kender is the natural choice.

Compare:

• Jeg kender betalingsmodtageren ikke / Jeg kender ikke betalingsmodtageren = I do not know the payee / I am not familiar with the payee
• Jeg ved ikke, hvem betalingsmodtageren er = I do not know who the payee is

English uses know for both ideas, but Danish usually does not.

Yes. Kender is the present tense of kende.

A few useful forms are:

• infinitive: kende
• present: kender
• past: kendte
• past participle: kendt

So Jeg kender ... means I know ... or I am familiar with ... in the present.

It is a very typical Danish compound noun.

It is made from:

• betaling = payment
• modtager = recipient
• -en = the definite ending

So the core compound is betalingsmodtager = payment recipient / payee, and betalingsmodtageren = the payment recipient / the payee.

Danish loves compound nouns, much more than English. Where English often uses several separate words, Danish often joins them into one.

That s is a linking element inside the compound.

So:

• betaling
• linking -s-
• modtager

This linking s is very common in Danish compounds, but it is not always predictable from English. In many cases, you simply learn the compound as a whole.

So betalingsmodtager is the standard form, not betalingmodtager.

Because Danish usually marks definiteness by adding it to the noun itself.

For a common-gender noun:

• en modtager = a recipient
• modtageren = the recipient

In compounds, only the last part takes the definite ending:

• en betalingsmodtager
• betalingsmodtageren

That is why you do not say en the-recipient type structures. Danish normally attaches the definite article to the noun.

Slet ikke is stronger than plain ikke.

• ikke = not
• slet ikke = not at all / absolutely not

So slet ikke adds emphasis. It makes the denial stronger and clearer.

Compare:

• Jeg kender ikke betalingsmodtageren = I do not know the payee
• Jeg kender betalingsmodtageren slet ikke = I do not know the payee at all

A good learning tip is to treat slet ikke as a fixed chunk.

Yes, you could also say Jeg kender ikke betalingsmodtageren.

That version is a very straightforward negative sentence and is probably the safest pattern for a learner.

The given sentence, Jeg kender betalingsmodtageren slet ikke, is also natural, but it gives extra punch to slet ikke by placing it at the end. It sounds more emphatic, a bit like ending on not at all in English.

So the difference is mostly about focus and style:

• Jeg kender ikke betalingsmodtageren = neutral
• Jeg kender betalingsmodtageren slet ikke = stronger, more emphatic

Then Danish usually puts the pronoun before the negation:

• Jeg kender ham ikke
• Jeg kender ham slet ikke

That is very common word order.

So with a full noun phrase, Danish has a bit more flexibility, but with short unstressed pronouns like ham, hende, den, det, the pronoun normally comes earlier.

It is understandable, but it sounds fairly formal and administrative, especially in banking, payments, apps, or official messages.

In everyday conversation, people might more often use:

• a name
• ham / hende
• firmaet
• a simpler description depending on context

So this sentence sounds like something you might see in a banking or fraud-check context rather than casual small talk.

Yes. Kende does not only apply to people. It can also mean be familiar with a company, place, name, system, or concept.

So if betalingsmodtageren is a company or organization, Jeg kender betalingsmodtageren slet ikke can still mean that the speaker is not familiar with that recipient at all.

In other words, kende is broader than just personal acquaintance.
