De verzekering dekt de herstelkosten.

Dekt is the third-person singular present tense of the verb dekken.

• dekken = to cover
• ik dek = I cover
• jij dekt = you cover
• hij/zij/het dekt = he/she/it covers

In De verzekering dekt de herstelkosten, the subject is de verzekering (the insurance), which is singular, so the verb must be dekt.

They use de for two different reasons:

1. de verzekering
   Verzekering is simply a noun that takes the article de. You have to learn this with the noun.

2. de herstelkosten
   Herstelkosten is plural, and all plural nouns in Dutch take de.

So even if the singular form of the second noun were a het word, the plural would still be de.

It is plural.

• de kost = the cost (less common in everyday Dutch)
• de kosten = the costs / expenses

So de herstelkosten means the repair costs or the cost of repairs. In practice, Dutch often uses kosten in the plural where English might sometimes use singular cost.

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

It is made from:

• herstel = repair, recovery, restoration
• kosten = costs

So:

• herstel + kosten = herstelkosten

A useful rule for Dutch compounds:

• the last part is the main part of the word

That means:

• the whole word is a kind of kosten
• its article and grammatical behavior follow kosten
• and because kosten is plural, the whole compound is plural too

This is standard Dutch main clause word order:

• subject: De verzekering
• verb: dekt
• object: de herstelkosten

Dutch main clauses usually put the finite verb in second position. Here the subject comes first, so the verb comes right after it.

Structure:

• De verzekering | dekt | de herstelkosten

That is very normal Dutch sentence structure.

Usually verzekering means insurance, insurance cover, or insurance policy, depending on context.

In this sentence, De verzekering dekt de herstelkosten most naturally means:

• The insurance covers the repair costs
• or The insurance policy covers the repair costs

If you specifically want to say the insurer / insurance company, Dutch often uses de verzekeraar.

So:

• de verzekering = the insurance / policy / coverage
• de verzekeraar = the insurer

Yes, often you could.

• reparatiekosten = repair costs
• herstelkosten = repair/restoration costs

In many contexts they are very close. But there can be a slight nuance:

• reparatie often focuses on fixing something broken
• herstel can sound a bit broader, like restoration or bringing something back into proper condition

In insurance or formal contexts, herstelkosten sounds very natural.

Here de herstelkosten refers to specific repair costs, so the article is natural.

• De verzekering dekt de herstelkosten.
  = The insurance covers the repair costs.

If you omit the article, the sentence becomes less specific and may sound incomplete or unnatural in this context.

Dutch can use bare plurals in some general statements, but with a concrete sentence like this, de herstelkosten is the normal choice.

Dekt is pronounced roughly like dehkt, with a short e sound.

A few points:

• the e is short, like in English bed
• the k is clearly pronounced
• the final t is also pronounced

So it is a short, crisp one-syllable word: dekt.

The dictionary form is exactly verzekering. It is a singular noun.

Useful related words:

• verzekeren = to insure
• de verzekering = the insurance / insurance policy
• de verzekeraar = the insurer
• verzekerd = insured

So this sentence is built from a very common insurance-related word family.

It sounds neutral and very natural. It would fit well in:

• everyday conversation
• insurance documents
• customer service language
• written explanations

It is not especially informal, but it is also not overly formal. It is exactly the kind of straightforward sentence you would expect in practical Dutch.
