Den långa texten ska innehålla alla svar, åtminstone enligt läraren.

Swedish usually uses double definiteness when a noun is definite and has an adjective in front of it.

So you get three pieces working together:

• den = the definite article for a common-gender noun
• långa = the adjective in its definite form
• texten = text with the definite ending -en

So Den långa texten means the long text.

Compare:

• en lång text = a long text
• texten = the text
• den långa texten = the long text

den lång texten is wrong because the adjective must be in the definite form långa, not lång.

Because adjectives in Swedish change form depending on grammar.

Here, texten is:

• common gender: en text
• definite: texten

When an adjective comes before a definite noun, it usually takes -a:

• en lång text = a long text
• den långa texten = the long text

So långa is the form used with definite nouns.

In Swedish, definiteness is often shown by attaching an ending directly to the noun.

• en text = a text
• texten = the text

Since text is a common-gender noun, its definite singular form is texten.

This is very different from English, where you normally just add the in front.

Because text is a common-gender noun, not a neuter noun.

In Swedish:

• common gender nouns use en / den
• neuter nouns use ett / det

Since it is en text, the definite article is den:

• en text
• den långa texten

If the noun were neuter, you would use det instead.

ska is a modal verb. It often means things like:

• will
• is supposed to
• is to
• should, depending on context

In this sentence, it suggests that the text is supposed to contain all the answers, or is expected to contain them.

So ska innehålla is something like:

• is supposed to contain
• should contain
• will contain

The exact best translation depends on context, but the grammar is the same.

After a modal verb such as ska, kan, vill, måste, Swedish uses the infinitive form of the main verb.

So:

• ska innehålla = is supposed to contain

Not:

• ska innehåller ❌

This is similar to English:

• will contain
• not will contains

So innehålla stays in the infinitive after ska.

Innehålla means to contain.

It is an infinitive ending in -a, which is very common in Swedish.

Some useful forms are:

• innehålla = infinitive, to contain
• innehåller = present tense, contains / is containing
• innehöll = past tense, contained
• innehållit = supine/past participle-related form, depending on construction

In your sentence, it appears in the infinitive because it follows ska.

Both can exist, but they mean slightly different things.

• alla svar = all answers
• alla svaren = all the answers

In Swedish, alla can be followed by either an indefinite plural noun or a definite plural noun, depending on the meaning.

Here, alla svar is a natural general expression meaning all answers.

If you said alla svaren, it would sound more specifically like a particular known set of answers.

Because svar is one of those Swedish nouns whose singular and plural forms are the same.

So:

• ett svar = an answer
• två svar = two answers
• alla svar = all answers

Only the article or surrounding words tell you whether it is singular or plural.

This is similar to some English words where the form does not change much, though Swedish has several nouns like this.

Åtminstone means at least.

It adds a kind of limitation or qualification:

• The long text is supposed to contain all the answers, at least according to the teacher.

So the speaker is not fully guaranteeing that it really does contain all the answers; they are saying that this is true at least from the teacher’s point of view.

It can appear in different places in Swedish sentences, but here it introduces the phrase enligt läraren.

Literally, it means according to the teacher.

• enligt = according to
• läraren = the teacher

So åtminstone enligt läraren means:

• at least according to the teacher

This is a very useful expression in Swedish:

• enligt honom = according to him
• enligt henne = according to her
• enligt boken = according to the book

Läraren is the definite form: the teacher.

• en lärare = a teacher
• läraren = the teacher

Using läraren suggests a specific teacher that both speaker and listener can identify from context.

That is why enligt läraren means according to the teacher, not just according to a teacher.

Not always. Swedish punctuation is often a little more flexible here than learners expect.

The comma in this sentence helps mark off the final comment:

• åtminstone enligt läraren

It makes that part feel a bit like an added aside: at least according to the teacher.

Without the comma, the sentence would still usually be understandable:

• Den långa texten ska innehålla alla svar åtminstone enligt läraren.

But the comma can make the structure clearer and the tone slightly more natural in writing.

The basic structure is:

• Den långa texten = subject
• ska = finite verb
• innehålla alla svar = rest of the verb phrase/object
• åtminstone enligt läraren = adverbial/comment phrase

So the sentence follows normal Swedish main-clause word order, where the finite verb comes in second position:

Den långa texten + ska + innehålla alla svar, åtminstone enligt läraren

This is standard Swedish V2 word order. Because the subject comes first, the verb comes right after it.
