Enten bruger hun appen, eller også går hun ind på hjemmesiden.

It sets up two alternatives, like either ... or ... in English.

• enten = either
• eller også = or / or else / alternatively

So the structure is:

• Enten
  • first option
• eller også
  • second option

This is a very common Danish pattern for presenting a choice.

Because Danish main clauses normally follow the V2 rule: the finite verb comes in the second position.

Here, enten is placed first in the clause, so the verb must come right after it:

• Enten bruger hun appen

Literally in terms of order:

• first position: Enten
• second position: bruger
• then the subject: hun

If the sentence started with the subject instead, you would get:

• Hun bruger appen

But once enten is moved to the front, inversion happens.

Not really in the usual English sense of also.

In eller også, the word også is part of a very common idiomatic way to introduce the second alternative. It often feels a bit like or else or alternatively.

So here, eller også should usually be learned as a chunk.

Yes, you can sometimes use just eller instead, but then the sentence structure usually changes a little, for example:

• Enten bruger hun appen, eller hun går ind på hjemmesiden.

So også is not just extra decoration; it affects how the clause is built.

For the same V2 reason as in the first clause.

In the second clause, også is effectively in the first position after eller, so the verb comes next:

• eller også går hun ind på hjemmesiden

Clause structure:

• first position: også
• second position: går
• then the subject: hun

That is why you get går hun.

No. In this context, går ind på hjemmesiden is an idiomatic digital expression meaning something like:

• go onto the website
• open the website
• visit the website
• access the website

Literally, gå ind på can sound like go in/on(to), but with websites it is a normal Danish way to talk about entering or opening a site online.

Because Danish usually puts the definite article at the end of the noun.

So:

• en app = an app
• appen = the app

and:

• en hjemmeside = a website
• hjemmesiden = the website

The ending -en shows that these nouns are definite. Both app and hjemmeside are common-gender nouns, so they take en in the indefinite form and -en in the definite form.

Because på is the normal preposition used with websites, pages, platforms, and similar digital spaces in Danish.

So Danish commonly says:

• på hjemmesiden = on the website
• på nettet = on the internet
• på Facebook

Also, the expression gå ind på specifically requires på here.

• til hjemmesiden would sound more like movement toward the website, not normal website usage.
• i hjemmesiden is not the usual choice for this meaning.

Yes, it is normal in standard written Danish here.

The sentence contains two full main clauses:

• Enten bruger hun appen
• eller også går hun ind på hjemmesiden

Since both parts are complete clauses, a comma before the second one is standard and a good habit for learners to follow.

Because the sentence is built as two full coordinated clauses, and each clause has its own subject and verb:

• Enten bruger hun appen
• eller også går hun ind på hjemmesiden

Repeating hun makes the structure clear and balanced.

You can sometimes avoid repeating the subject in Danish if the structure is tighter, but in this sentence the repeated hun is the most natural and straightforward choice.

Yes, definitely. Enten ... eller ... is very common.

For example:

• Enten bruger hun appen, eller hun går ind på hjemmesiden.

That said, eller også is also very common and often sounds especially natural when introducing the second full alternative. It gives the second option a slightly stronger alternative/otherwise feel.

So both patterns are useful:

• enten ... eller ...
• enten ... eller også ...
