Brillestyrken og bygningsfejlen står i dokumentet.

Those endings mark the definite form in Danish.

• brillestyrke = eyeglass strength / lens strength

• brillestyrken = the eyeglass strength

• bygningsfejl = building defect / construction error

• bygningsfejlen = the building defect

• dokument = document
• dokumentet = the document

Unlike English, Danish usually adds the definite article to the end of the noun instead of putting a separate word like the in front.

Very roughly:

• common gender nouns often take -en in the definite singular
• neuter nouns often take -et in the definite singular

So here:

• brillestyrken → common gender
• bygningsfejlen → common gender
• dokumentet → neuter

You need to know the noun’s gender.

Danish has two genders:

• common gender: takes en as the indefinite article, and usually -en in the definite form
• neuter: takes et as the indefinite article, and usually -et in the definite form

Examples from the sentence:

• en brillestyrke → brillestyrken
• en bygningsfejl → bygningsfejlen
• et dokument → dokumentet

So learning a noun together with its article is very helpful:

• en brillestyrke
• en bygningsfejl
• et dokument

In Danish, stå is often used in the sense of be written, appear, or be stated somewhere.

So:

• Det står i dokumentet = It says so in the document / It is written in the document

That is a very common Danish expression.

In this sentence, står i dokumentet means something like:

• is stated in the document
• is written in the document
• appears in the document

Using er would usually just mean is, which is less natural if the point is that the information is written down in a text.

Because Danish verbs in the present tense do not change according to singular or plural subjects.

So:

• jeg står
• du står
• han står
• vi står
• de står

The verb form stays står.

Even though the subject contains two nouns joined by og, the present-tense verb is still just står.

Yes. The subject is the whole coordinated noun phrase:

• brillestyrken og bygningsfejlen

The verb is:

• står

And the prepositional phrase telling where is:

• i dokumentet

So the structure is:

• Subject: brillestyrken og bygningsfejlen
• Verb: står
• Prepositional phrase: i dokumentet

Because Danish normally uses i with something like a document, text, report, book, or letter when the meaning is in the document/text.

Examples:

• Det står i bogen = It is written in the book
• Det står i rapporten = It is written in the report
• Det står i dokumentet = It is written in the document

Using på would usually suggest something more physical, like being on the surface of something, and it would not sound natural here for written content.

Yes. Danish forms compound nouns very freely, much like German.

brillestyrken

This is built from:

• brille = glasses
• styrke = strength / power

Together, brillestyrke means the strength or prescription of glasses/lenses.

bygningsfejlen

This is built from:

• bygning = building
• fejl = error / defect / fault

Together, bygningsfejl means a building defect, construction defect, or structural fault, depending on context.

In Danish compounds, the last part is usually the main noun, and the earlier part modifies it.

That -s- is a common linking element in Danish compounds.

• bygning
  • fejl → bygningsfejl

This inserted -s- does not usually have a separate meaning; it just helps form the compound in a natural way.

You will see this in many Danish compounds, though not all of them. It is something learners gradually get used to rather than something that always follows a simple rule.

It usually refers to the optical strength or prescription strength of glasses or lenses.

Depending on context, an English translation could be:

• eyeglass prescription
• lens strength
• glasses strength

A Danish speaker would normally understand it as the corrective strength associated with glasses.

Literally, yes, because står basically means stands. But in natural English, that would usually sound wrong here.

A better translation would be:

• is stated in the document
• is written in the document
• appears in the document

This is a good example of where a literal word-for-word translation is less useful than learning the Danish expression as a whole.

A careful approximate pronunciation is:

BRIL-leh-styr-ken og BYG-nings-fylen står i do-ko-MEN-ted

A few notes:

• styr contains the Danish y, which English does not really have
• bygnings- begins with byg-, where y again is a Danish vowel
• står has the Danish letter å, pronounced somewhat like the vowel in thought in many English accents
• dokumentet is often pronounced with a soft final -et, not with a strong English-style t

If you want to sound more natural, it helps to learn the whole sentence as one rhythm unit rather than one word at a time.

Yes, but the structure and emphasis would change.

For example:

• Brillestyrken og bygningsfejlen står i dokumentet.
• Der står brillestyrken og bygningsfejlen i dokumentet.

The first version is the more straightforward one here: the subject comes first.

Using der står is possible in some contexts, but it often feels more like introducing or presenting information, and it may not be the most neutral version here.

So the given sentence is a normal, clear main-clause structure.

Yes. It is a standard Danish main clause.

The basic pattern is:

• Subject + verb + other elements

So here:

• Brillestyrken og bygningsfejlen = subject
• står = finite verb
• i dokumentet = adverbial/prepositional phrase

This is exactly the kind of word order you would expect in a simple statement.

Yes, because Danish main clauses follow the V2 rule: the finite verb stays in the second position.

So if you front i dokumentet, you get:

• I dokumentet står brillestyrken og bygningsfejlen.

That is also correct.

Notice that the verb står still comes second. You do not say:

• I dokumentet brillestyrken og bygningsfejlen står ❌

So this sentence is a nice example of Danish V2 word order.
