Det er ligesom i går.

In this sentence, det is a very common Danish dummy subject, similar to English it in sentences like It is cold or It is the same as yesterday.

It does not always point to a specific thing. Sometimes det refers to a situation, the weather, a general state, or something understood from context.

So in Det er ligesom i går, det can mean something like:

• it
• this situation
• things
• the way it is now

The exact reference depends on context.

Er is the present tense of at være (to be).

So:

• at være = to be
• er = am / is / are

Because the sentence is in the present tense, Danish uses er:

• Det er ... = It is ...

Danish verbs do not change for person the way English verbs do. So you say:

• jeg er = I am
• du er = you are
• det er = it is
• vi er = we are

The verb form stays er for all of them.

Here ligesom means like, just like, or similar to.

In this sentence, it compares the current situation to yesterday:

• Det er ligesom i går = It is like yesterday / It is just like yesterday

A useful thing to know is that ligesom can also have other uses in spoken Danish, where it may sound more like kind of, like, or a filler word in conversation. But in this sentence, it is clearly being used for comparison.

That is a very common question.

In many cases, som is the basic word for as or which/who/that, while ligesom often adds the idea of similarity or just like.

For example:

• Hun er som sin mor = She is like her mother
• Hun er ligesom sin mor = She is just like her mother / similar to her mother

In real Danish, the difference is not always huge, and sometimes both can work depending on style and context. But ligesom often feels a bit more like in the same way as or similar to.

In this sentence, ligesom emphasizes resemblance to yesterday.

Because the Danish expression for yesterday is i går.

You should learn it as a fixed time expression:

• i går = yesterday
• i dag = today
• i morgen = tomorrow

Even though i often means in, in these expressions it is just part of the phrase. So you normally do not translate word by word.

A rough guide is:

• i sounds somewhat like English ee in see
• går has a vowel sound that English does not match perfectly, and the å is pronounced roughly like the vowel in more for many learners, though that is only approximate

Also, går often has the soft Danish r, which may be difficult at first.

A very rough learner-friendly approximation might be:

• ee gor

But that is only approximate. If you want to sound natural, it is best to listen to native audio, especially for the vowel in går.

This is the normal Danish main-clause word order:

• subject
  • verb
    • other elements

So:

• Det = subject
• er = verb
• ligesom i går = complement/adverbial phrase

That gives:

• Det er ligesom i går

This is very similar to normal English word order:

• It is like yesterday

Yes, in some contexts you can say Det er som i går, and it can sound more direct or slightly more neutral.

But ligesom often gives a stronger feeling of similarity or just like. Depending on tone and context, ligesom may sound a bit more conversational.

So:

• Det er som i går = It is as/like yesterday
• Det er ligesom i går = It is just like yesterday / It is similar to yesterday

Both are understandable, but ligesom is perfectly natural here.

It is generally neutral to informal and very natural in everyday speech.

The word ligesom is common in spoken Danish, and it often feels conversational. The sentence itself is simple and natural, not especially formal.

If you needed a more formal or precise sentence, you might choose different wording depending on context, but Det er ligesom i går is completely normal in ordinary Danish.

Yes. In spoken Danish, ligesom can sometimes be used a bit like English like as a filler or hesitation word.

For example, in conversation someone might say something where ligesom does not contribute much concrete meaning but helps structure speech.

However, in Det er ligesom i går, it is not just a filler. It has a real meaning: like or similar to.

So learners should be aware of both uses:

• meaningful comparison: Det er ligesom i går
• spoken filler: common in casual speech

Yes, definitely.

Even if the basic meaning is clear, the sentence can suggest different things depending on what people are talking about. For example, it could mean:

• the weather is like yesterday
• the mood is like yesterday
• a problem has happened again
• the situation has not changed

So the literal structure is simple, but the practical meaning depends on context. That is very common with sentences beginning with det in Danish.
