Det er typisk, at de ser fodbold i fjernsynet om søndagen.

Here det is a dummy subject, like English it in It is typical that....

So Det er typisk, at... means something like:

• It is typical that...
• It is typical for them to...
• That is typical

The word det does not refer to a specific thing here. It is just needed to make a normal Danish sentence structure.

At introduces a subordinate clause, in this case at de ser fodbold i fjernsynet om søndagen.

So the sentence is built like this:

• Det er typisk = main clause
• at de ser fodbold i fjernsynet om søndagen = subordinate clause

This is very similar to English that in It is typical that they watch football on Sundays, although English often leaves that out.

Because at de ser fodbold... is a subordinate clause, and Danish subordinate clauses normally keep the subject before the verb:

• de ser = they watch

So this is the normal order:

• at de ser fodbold

Compare that with main-clause word order, where Danish often has inversion after another element comes first. But here, after at, you usually just keep subject + verb.

In Danish, activities and sports are often used without an article, just as in English:

• ser fodbold = watch football
• spiller fodbold = play football

You would only add an article if you meant a specific football match, ball, or clearly defined instance. Here it means the general activity or kind of program, so fodbold appears without en or det.

Yes, literally i fjernsynet looks like in the television, but idiomatically it means on TV.

This is a fixed Danish way of speaking:

• i fjernsynet = on television, on TV

Learners often expect på fjernsynet because English uses on, but Danish commonly says i fjernsynet.

You may also hear:

• på tv
• i tv
• i fjernsynet

But in a sentence like this, i fjernsynet is a normal and natural phrasing.

Fjernsynet is the definite form: the television.

In Danish, some expressions use the definite form where English would not. So although English says on TV, Danish can say i fjernsynet, literally in the television.

This is something you often just learn as a set expression rather than translating word for word.

Om søndagen means on Sundays or on Sunday(s) in general.

The combination om + definite singular day is a common Danish way to talk about something that happens regularly on that day:

• om mandagen = on Mondays
• om fredagen = on Fridays
• om søndagen = on Sundays

So søndagen is definite singular, but the meaning is habitual or repeated, not just one specific Sunday.

Yes, om søndage is also possible, and it also means something like on Sundays.

Both can express repeated action, but there can be a slight difference in feel:

• om søndagen often sounds like a habitual pattern, something typical or usual
• om søndage can sound a little more neutral or general

In this sentence, om søndagen fits very well because the whole sentence is about what is typical.

Often yes, but the feeling can be slightly broader. Typisk can mean:

• characteristic
• usual
• just what you would expect
• a typical habit or pattern

So Det er typisk, at de ser fodbold i fjernsynet om søndagen suggests that this is a regular, characteristic thing for them to do.

In other contexts, Typisk! can also mean something like Typical!, especially when reacting to an annoying or predictable situation.

Yes. That version is also natural, and many learners find it easier to understand because it lines up well with English:

• Det er typisk for dem at se... = It is typical of them to watch...

The original sentence uses a that-clause structure:

• Det er typisk, at de ser...

The alternative uses for dem + infinitive:

• Det er typisk for dem at se...

Both are correct. The original sentence is slightly more focused on the fact that this happens; the alternative focuses a bit more directly on them.

Ser is the present tense of at se.

Here the present tense is used for a habitual action, just like in English:

• de ser fodbold om søndagen = they watch football on Sundays

So it does not mean they are necessarily watching football right now. It describes what they usually do.
