Om mandagen tager jeg toget til universitetet.

In Danish, om mandagen means on Mondays or on Monday(s) in a habitual, repeated sense.

• mandag = Monday
• om mandagen = on Mondays / on Monday, as a regular thing

The preposition om is often used for repeated time expressions like this:

• om mandagen = on Mondays
• om tirsdagen = on Tuesdays
• om sommeren = in the summer

If you mean a specific upcoming Monday, Danish would often just use mandag or på mandag, depending on context.

Mandagen is the definite form of mandag.

In Danish, nouns usually add the definite article to the end of the word:

• en mandag = a Monday
• mandagen = the Monday

In time expressions like om mandagen, Danish often uses the definite form even though English does not. So you should think of this as a fixed Danish pattern rather than trying to translate word-for-word.

Here, om is a preposition used in time expressions. In om mandagen, it gives the sense of on in English, especially for something habitual or recurring.

So although om can mean other things in other contexts, here it is best understood as part of the expression om + day/time word in the definite form.

Examples:

• om morgenen = in the morning
• om aftenen = in the evening
• om fredagen = on Fridays

This is because Danish follows the V2 rule in main clauses. That means the finite verb normally comes in the second position.

In this sentence, Om mandagen comes first. Because that first slot is already taken, the verb must come next:

• Om mandagen = first element
• tager = second element
• jeg = subject, after the verb

So:

• Jeg tager toget til universitetet. = I take the train to the university.
• Om mandagen tager jeg toget til universitetet. = On Mondays, I take the train to the university.

This verb-second pattern is very important in Danish.

Tager is the present tense of tage.

• at tage = to take
• jeg tager = I take / I am taking

Danish present tense is simple: you usually add -r to the infinitive.

Examples:

• at bo → bor
• at købe → køber
• at tage → tager

In this sentence, tager means take in a habitual sense: I take the train.

Toget is the definite form of tog:

• et tog = a train
• toget = the train

In Danish, transport expressions often use the definite form where English may or may not. So tage toget is the normal way to say take the train.

This is similar to:

• tage bussen = take the bus
• tage bilen = take the car

Even if English sometimes sounds more general, Danish commonly uses the definite form in these expressions.

Because universitet is a neuter noun in Danish:

• et universitet = a university
• universitetet = the university

For many Danish nouns:

• common gender (en-words) usually take -en in the definite form
• neuter (et-words) usually take -et in the definite form

So here:

• et tog → toget
• et universitet → universitetet

Because Danish uses the preposition til for to, and then the noun itself carries the definite meaning:

• til = to
• universitetet = the university

So til universitetet literally works like to the university.

Danish does not use a separate word like English the before most definite nouns. Instead, the definiteness is usually attached to the noun:

• skolen = the school
• byen = the city
• huset = the house

So:

• til skolen = to the school
• til byen = to the city

Yes, that is grammatically correct.

Both of these are possible:

• Om mandagen tager jeg toget til universitetet.
• Jeg tager toget til universitetet om mandagen.

The difference is mainly focus.

• Starting with Om mandagen emphasizes the time: On Mondays...
• Starting with Jeg is more neutral: I take the train to the university on Mondays.

The first version is especially natural if you are contrasting days or talking about a routine.

Normally, om mandagen suggests a habitual meaning: something that happens on Mondays in general.

So the sentence is usually understood as:

• On Mondays, I take the train to the university.

If you wanted to talk about one specific Monday, Danish would normally use a different expression, depending on the situation.

No, not quite. In standard Danish, jeg is often pronounced more like yai or even a very reduced ya in everyday speech, though pronunciation varies by region and speaking style.

Important point for learners: the spelling and pronunciation of jeg do not match English expectations very well.

So when reading this sentence aloud, pay special attention to:

• jeg = not hard j as in English jam
• toget = the g is often soft or not pronounced like an English hard g
• universitetet = the ending is lighter than English speakers often expect

A teacher or audio recording is especially helpful for this sentence because Danish pronunciation is less phonetic than the spelling suggests.
