Eers nadat aanspreeklikheid bevestig is, betaal die lugdiens vir die oornagverblyf.

Eers nadat means only after.

• nadat = after
• eers nadat = only after / not until after

So the sentence is more specific than a simple after. It means the airline will pay only once that condition has been met.

Compare:

• Nadat aanspreeklikheid bevestig is, betaal die lugdiens...
  = After liability has been confirmed, the airline pays...
• Eers nadat aanspreeklikheid bevestig is, betaal die lugdiens...
  = Only after liability has been confirmed does the airline pay...

So eers adds the idea of not before then.

That happens because nadat introduces a subordinate clause, and in Afrikaans subordinate clauses usually send the verb elements to the end.

Main clause:

• Aanspreeklikheid is bevestig.
  = Liability has been confirmed.

Subordinate clause after nadat:

• nadat aanspreeklikheid bevestig is
  = after liability has been confirmed

So the normal is bevestig order becomes bevestig is at the end of the clause.

This is a very common Afrikaans pattern:

• omdat hy moeg is = because he is tired
• as sy gekom het = if she had come
• nadat dit besluit is = after it has been decided

Aanspreeklikheid means liability or responsibility in a legal/financial sense.

In this sentence, it refers to the question of whether the airline is officially responsible for paying.

So it is not just general responsibility like taking care of something in an everyday way. It often has a more formal tone, especially in legal, insurance, travel, or business contexts.

Related word:

• aanspreeklik = liable / responsible

Example:

• Die maatskappy is aanspreeklik vir die skade.
  = The company is liable for the damage.

The comma separates the opening subordinate clause from the main clause:

• Eers nadat aanspreeklikheid bevestig is, = subordinate clause
• betaal die lugdiens vir die oornagverblyf. = main clause

In the main clause, Afrikaans follows the verb-second rule. That means the finite verb usually comes in the second position.

If the sentence starts with something other than the subject, the verb still stays second, and the subject moves after it.

Underlying basic order:

• Die lugdiens betaal vir die oornagverblyf.

But because the sentence starts with the time/condition part:

• Eers nadat aanspreeklikheid bevestig is, betaal die lugdiens vir die oornagverblyf.

So betaal comes before die lugdiens because the first position is already occupied by the opening clause.

In Afrikaans, betaal vir often means pay for something.

So:

• betaal vir die oornagverblyf = pay for the overnight accommodation

A useful distinction is:

• betaal iemand = pay someone
• betaal vir iets = pay for something

Examples:

• Ek betaal die hotel.
  = I pay the hotel.
  This sounds like paying the business/entity.
• Ek betaal vir die hotel.
  = I pay for the hotel.
  This focuses on covering the cost.

In your sentence, the idea is that the airline covers the cost of the overnight stay, so vir is natural.

Oornagverblyf means overnight accommodation or an overnight stay.

It is a compound noun, which is very common in Afrikaans.

It is built from:

• oornag = overnight
• verblyf = accommodation / stay / lodging

So literally it is something like overnight lodging.

Afrikaans often joins words together into one compound where English might use two or three words:

• lugdiens = airline
• treinstasie = train station
• reisversekering = travel insurance
• oornagverblyf = overnight accommodation

Yes. In this sentence, aanspreeklikheid bevestig is is passive.

It means:

• liability has been confirmed or
• liability is confirmed, depending on context

The important point is that aanspreeklikheid is receiving the action, not doing it.

Active:

• Hulle bevestig die aanspreeklikheid.
  = They confirm the liability.

Passive:

• Die aanspreeklikheid is bevestig.
  = The liability has been confirmed.

Inside the subordinate clause, that becomes:

• nadat aanspreeklikheid bevestig is

So yes, this is a passive structure.

Die lugdiens means the airline.

Afrikaans uses die as the definite article for all nouns, whether singular or plural in most ordinary contexts.

So:

• die lugdiens = the airline
• ’n lugdiens = an airline

In this sentence, a specific airline is meant, not just any airline in general, so die is used.

That is close word-for-word, but it sounds unnatural in English. A more natural English version would be:

• Only after liability has been confirmed does the airline pay for the overnight accommodation.
• or The airline only pays for the overnight accommodation after liability has been confirmed.

So the Afrikaans structure is fine, but English usually needs a slightly different structure to sound natural.

Yes, but moving eers can change the emphasis.

Your sentence:

• Eers nadat aanspreeklikheid bevestig is, betaal die lugdiens vir die oornagverblyf.

This strongly emphasizes only after that point.

Another possible wording:

• Die lugdiens betaal eers vir die oornagverblyf nadat aanspreeklikheid bevestig is.

That is also natural and means roughly:

• The airline only pays for the overnight accommodation after liability has been confirmed.

So both are possible, but the original sentence puts stronger focus on the condition right at the beginning.

A good way to break it down is this:

1. Main clause by itself:

   • Die lugdiens betaal vir die oornagverblyf.
   • The airline pays for the overnight accommodation.

2. Add the time/condition clause:

   • nadat aanspreeklikheid bevestig is
   • after liability has been confirmed

3. Add eers for only after:

   • eers nadat aanspreeklikheid bevestig is

4. Put that clause first:

   • Eers nadat aanspreeklikheid bevestig is, betaal die lugdiens vir die oornagverblyf.

So the sentence is basically:

• Only after + condition, + main action

That pattern is very common in Afrikaans formal writing.
