Tidsperioden står i boganmeldelsen.

Both can be definite, but they work a little differently.

• tidsperioden = the time period using the definite ending -en
• den tidsperiode can also mean that time period or the time period, but Danish usually prefers the suffixed definite form when the noun stands alone.

So in a simple sentence like this, tidsperioden is the most natural choice.

Also note that tidsperiode is a common gender noun, so its definite singular ending is -en:

• en tidsperiode
• tidsperioden

Because Danish, like German, commonly forms compound nouns by writing them as a single word.

So:

• tid = time
• periode = period

Together:

• tidsperiode = time period

The -s- in the middle is a common linking element in Danish compounds. It does not have to mean possession here; it just helps connect the parts naturally.

Other examples of this kind of compounding are very common in Danish.

Yes, står literally means stands, but Danish often uses stå in a broader way than English does.

In this sentence, står means something like:

• is written
• appears
• is stated

So Tidsperioden står i boganmeldelsen is not saying the time period is physically standing somewhere. It means the information is found in the book review.

This is a very common Danish usage:

• Det står i avisen = It says so in the newspaper
• Det står i bogen = It is written in the book

Because Danish normally uses i for something written in a text, document, book, article, review, and so on.

So:

• i bogen = in the book
• i artiklen = in the article
• i boganmeldelsen = in the book review

English sometimes says in and sometimes uses other phrasing, but in Danish i is the natural preposition here.

Using på would usually not sound right for the meaning written in the review.

Because the sentence refers to a specific book review: the book review.

Compare:

• en boganmeldelse = a book review
• boganmeldelsen = the book review

The definite ending -en shows that the review is known or specific in context.

Also, boganmeldelse is another compound noun:

• bog = book
• anmeldelse = review

So:

• boganmeldelse = book review
• boganmeldelsen = the book review

No, this is standard Danish main-clause word order:

• Tidsperioden = subject
• står = verb
• i boganmeldelsen = prepositional phrase

So it follows the normal pattern: Subject + verb + other elements

Danish main clauses usually place the finite verb in second position, and this sentence fits that rule naturally.

Grammatically, maybe in some very unusual context, but it would usually sound wrong for this meaning.

• står i boganmeldelsen means is written/stated in the book review
• er i boganmeldelsen would sound more like is in the book review in a very literal or physical sense

When talking about information contained in a text, Danish strongly prefers står rather than er.

Yes, står is present tense, but in Danish this is perfectly normal even if the review was written earlier.

The present tense is often used for facts that are still true now, such as what a text says:

• Det står i anmeldelsen = It says / It is written in the review

So even if the review was published years ago, the sentence can still use present tense because the text still contains that information.

A rough English-friendly guide might be:

TIDS-peh-ree-oh-den stor ee BOH-an-mel-del-sen

A few useful points:

• d is often softer than English learners expect
• står has the Danish å, somewhat like aw/o in English, but not exactly
• Danish pronunciation is often much less phonetic than spelling suggests

If you are learning pronunciation, it helps to listen to native audio because Danish vowel sounds and soft consonants can be tricky from spelling alone.

Yes. Even if the general meaning is clear, tidsperioden can refer to different kinds of time spans depending on context, for example:

• the historical period discussed in the book
• the period when the story takes place
• the period covered by the review or book

So the sentence itself is grammatically straightforward, but the exact reference of tidsperioden depends on the surrounding context.
