Jeg arbejder hjemmefra i dag.

Yes. Arbejder is the present tense of at arbejde = to work.

So:

• jeg arbejder = I work / I am working

In Danish, the present tense often covers both the simple present and the English present progressive, depending on context. So Jeg arbejder hjemmefra i dag can mean both:

• I work from home today
• I’m working from home today

English makes a bigger distinction here than Danish does.

Hjemmefra means from home.

It is built from:

• hjemme = at home
• fra = from

Together, hjemmefra is a very common fixed expression meaning from home, especially in sentences about working or studying remotely.

Examples:

• Jeg arbejder hjemmefra. = I work from home.
• Hun studerer hjemmefra. = She studies from home.

Because hjemme and hjemmefra do not mean exactly the same thing.

• hjemme = at home
• hjemmefra = from home

Compare:

• Jeg arbejder hjemme. = I work at home / I’m working at home
• Jeg arbejder hjemmefra. = I work from home

In many real situations, both are possible, but hjemmefra is especially common when talking about remote work.

That is a very normal word order in Danish.

The sentence structure is:

• Jeg = subject
• arbejder = verb
• hjemmefra = adverbial
• i dag = time expression

Putting the time expression at the end is common and natural:

• Jeg arbejder hjemmefra i dag.

But Danish also allows you to move the time phrase to the front:

• I dag arbejder jeg hjemmefra.

That version is also very common. When you put i dag first, the verb must come before the subject, which is a standard Danish word-order rule.

Because Danish follows the verb-second rule in main clauses.

That means the finite verb usually comes in the second position, no matter what comes first.

So:

• Jeg arbejder hjemmefra i dag.
  • first element: Jeg
  • second element: arbejder

If you move i dag to the front:

• I dag arbejder jeg hjemmefra.
  • first element: I dag
  • second element: arbejder

This is very important in Danish word order. English learners often expect I dag jeg arbejder..., but that is incorrect in a main clause.

It is normally written as two words in Danish: i dag.

So write:

• i dag

not:

• idag

This is a very common thing learners notice because some other Scandinavian languages often write the equivalent differently.

In everyday Danish, jeg is often pronounced something like:

• yai
• or a very reduced ya

The exact sound varies by speaker and region, and Danish pronunciation is often more reduced than the spelling suggests.

So although it is spelled jeg, do not expect it to sound like each letter is clearly pronounced.

The spelling can look intimidating, but in normal speech it is much smoother than it looks.

A rough learner-friendly guide is something like:

• AR-bye-der
• or more naturally, with reduced sounds, something closer to AH-bye-der

The middle part comes from arbejde and contains a sound similar to bye.

As with a lot of Danish, the spoken form is often less crisp than the written form, so listening to native audio is especially helpful here.

The sentence specifically says today because of i dag.

So the clearest meaning is:

• I’m working from home today

Without i dag, the sentence becomes more general:

• Jeg arbejder hjemmefra. = I work from home / I’m working from home

That could describe a habit, a usual arrangement, or what is happening right now, depending on context.

Grammatically, Danish speakers would strongly prefer hjemmefra here.

• Jeg arbejder hjemmefra i dag. = natural
• Jeg arbejder fra hjemmet i dag. = understandable, but unnatural in ordinary conversation

So for normal modern Danish, especially when talking about remote work, hjemmefra is the expression to learn.

Yes. It is a complete and natural Danish sentence.

It has everything it needs:

• Jeg = subject
• arbejder = finite verb
• hjemmefra = adverbial phrase
• i dag = time expression

It works perfectly well as a full statement in everyday conversation.

Absolutely. It is very natural, especially in modern everyday speech about work schedules.

You might hear it in contexts like:

• telling a colleague your work arrangement
• explaining why you are not in the office
• answering a question about your plans

For example:

• Kommer du ind på kontoret?
• Nej, jeg arbejder hjemmefra i dag.

So this is a very useful sentence to know.
