Vi hvisker i biblioteket, så de andre kan læse i ro.

Yes. hvisker is the present tense of at hviske.

In Danish, the present tense often covers both:

• simple present: We whisper
• present progressive: We are whispering

So Vi hvisker i biblioteket can mean either one, depending on context.

Because Danish usually forms the present tense by adding -r to the verb.

For example:

• at hviske → hvisker
• at læse → læser

So hvisker simply means whisper / am whispering / are whispering, depending on context.

i means in or inside.

biblioteket means the library:

• et bibliotek = a library
• biblioteket = the library

So i biblioteket means in the library.

That -et is the definite ending. Danish often puts the onto the end of the noun instead of using a separate word like English does.

With this noun:

• et bibliotek = a library
• biblioteket = the library

The word bibliotek is a neuter noun, which is why the definite singular ending is -et.

Here så means so or so that.

It introduces the idea of purpose or result:

• Vi hvisker i biblioteket, så de andre kan læse i ro.
• We whisper in the library so that the others can read in peace.

In other contexts, så can also mean then or so, but here the meaning is clearly so that.

Because så introduces a dependent clause here.

In this kind of clause, Danish normally keeps the subject before the finite verb:

• de andre kan læse

If you said kan de andre læse, that would sound like a question or a different main-clause structure.

So in this sentence, de andre kan læse is the normal word order.

de andre means the others or the other people.

• andre = other / others
• de here works like the in plural

So:

• de andre = the others

In this sentence, it most naturally means the other people in the library.

Because after a modal verb like kan, Danish uses the infinitive without at.

So:

• kan læse = can read
• not kan at læse

This is the same idea as in English, where we say can read, not can to read.

Other common Danish modal verbs work the same way:

• vil læse = want to read / will read
• skal læse = must / have to read
• må læse = may / be allowed to read

Here kan means something like can / are able to / have the opportunity to.

It is not mainly about formal permission. The idea is:

We whisper so that the others are able to read in peace.

So kan here expresses that whispering makes it possible for them to read comfortably and without disturbance.

i ro is a common expression meaning:

• in peace
• quietly
• without being disturbed

So læse i ro means read in peace or read without interruption.

Word-for-word, it is something like in calm, but the natural English meaning is in peace or quietly.

The comma separates the two parts of the sentence:

• Vi hvisker i biblioteket
• så de andre kan læse i ro

In Danish, commas are often used to mark clause boundaries clearly. Here the comma shows that the second part explains the purpose/result of the first part.

So the comma helps structure the sentence, even if English punctuation might not always match it exactly.

It can be either, depending on context.

Because Danish present tense is flexible, Vi hvisker i biblioteket can mean:

• We whisper in the library as a general rule or habit
• We are whispering in the library right now

This sentence sounds very natural as a general statement about polite behavior, but grammar alone does not force only that meaning.
