Det er forkert at stjæle.

Here, det is a dummy subject, similar to English it in It is wrong to steal.

It does not refer to a specific thing. It is just used because Danish sentences usually need a subject. So:

• Det er forkert = It is wrong
• at stjæle = to steal

Together: It is wrong to steal.

Er is the present tense of at være (to be), so det er forkert means it is wrong.

You use er because the sentence describes a general fact or judgment.

• Det er forkert at stjæle = It is wrong to steal

Bliver means becomes or is getting, so it would change the meaning:

• Det bliver forkert = It becomes wrong / It turns out wrong

That is not what this sentence means.

Forkert usually means wrong, incorrect, or mistaken, depending on context.

In this sentence, it means morally wrong.

Compare:

• Det er forkert at stjæle = It is wrong to steal
• Svaret er forkert = The answer is wrong / incorrect

So forkert can describe both:

• moral wrongness
• factual incorrectness

At is the infinitive marker, like English to in to steal.

So:

• at stjæle = to steal

This is the basic infinitive form of the verb. After adjectives like forkert, Danish often uses this structure:

• Det er + adjective + at + infinitive

Examples:

• Det er svært at forstå = It is difficult to understand
• Det er vigtigt at lytte = It is important to listen

No, stjæle is an irregular verb.

Its basic forms are:

• at stjæle = to steal
• stjæler = steals / am stealing / are stealing
• stjal = stole
• har stjålet = have/has stolen

Examples:

• Han stjæler penge = He steals money
• Han stjal pengene = He stole the money
• Han har stjålet pengene = He has stolen the money

Yes, you can, but the tone is a little different.

• forkert = wrong
• galt = wrong, bad, sometimes a bit stronger or more idiomatic in certain contexts

Det er forkert at stjæle is very clear and neutral. Det er galt at stjæle is also natural and means something like It is wrong/bad to steal.

A learner should probably start with forkert, because it is very straightforward.

Because standard Danish main clause word order is:

• subject + verb + complement

So:

• Det = subject
• er = verb
• forkert = complement
• at stjæle = infinitive phrase

That gives:

• Det er forkert at stjæle

Det forkert er at stjæle is not normal Danish word order.

Yes. At stjæle er forkert is grammatically correct and means the same thing: To steal is wrong.

The difference is mainly style:

• Det er forkert at stjæle = more common, natural, everyday
• At stjæle er forkert = a bit more direct or formal

Both are correct.

Stjæle can be tricky for English speakers because of the consonant cluster stj and the vowel æ.

A rough guide:

• stj sounds somewhat like sty at the beginning, but smoother
• æ is like the vowel in English cat, though not exactly the same
• the final -e is a weak sound

So a rough approximation is something like STYEH-luh, but that is only approximate.

The best thing is to listen to native audio, because Danish pronunciation is often less phonetic than spelling suggests.

It is functioning as an adjective here.

In Det er forkert at stjæle, forkert describes the action at stjæle as being wrong.

Danish often uses the neuter singular form of adjectives in sentences with det er:

• Det er godt = It is good
• Det er svært = It is difficult
• Det er forkert = It is wrong

So even though it may look a bit adverb-like to an English speaker, it is best understood here as the adjective form used with det.

Yes, in a way. Det is the grammatical subject, while at stjæle gives the real content of what is being judged.

So the structure is a bit like:

• It is wrong to steal

English works the same way. It is the formal subject, and to steal expresses the actual action being discussed.

You usually put ikke after the verb:

• Det er ikke forkert at stjæle

But be careful: this means It is not wrong to steal, which changes the meaning completely.

Basic pattern:

• Det er forkert = It is wrong
• Det er ikke forkert = It is not wrong

In a yes/no question, Danish usually puts the verb before the subject:

• Er det forkert at stjæle? = Is it wrong to steal?

This is a very common pattern:

• Det er svært → Er det svært?
• Det er vigtigt → Er det vigtigt?
• Det er forkert at stjæle → Er det forkert at stjæle?
