Jeg springer over, jeg er for træt.

Here springer over means skip, pass, or sit this one out.

The basic verb is at springe over, which literally can mean to jump over, but in everyday Danish it is also very commonly used idiomatically for skipping something.

So in this sentence, it does not mean physical jumping. It means something like:

• I’m skipping.
• I’ll pass.
• I’m sitting this out.

Because springer is the present tense form of the verb.

• infinitive: at springe = to jump / to skip
• present tense: springer = jump / am jumping / skip / am skipping

With jeg, Danish uses the same present-tense verb form as with other subjects:

• jeg springer
• du springer
• han/hun springer

So Jeg springer over literally uses the normal present tense: I skip / I am skipping.

It can mean either, depending on context.

In Danish, the present tense is often used for something happening now or for a decision about the near future.

So Jeg springer over can sound like:

• I’m skipping
• I’ll skip
• I’m going to pass

In this sentence, it most naturally sounds like a decision being made now: I’ll skip it / I’m skipping, I’m too tired.

Because at springe over is a verb + particle combination, similar to an English phrasal verb.

Compare English:

• to skip out
• to pass up
• to sit out

In Danish, the particle over stays separate:

• at springe over
• jeg springer over

If there is an object pronoun, it often goes in between:

• Jeg springer det over = I’m skipping it

So this is normal Danish structure, not a spelling mistake.

Here for means too.

So:

• træt = tired
• for træt = too tired

That is a very important difference. It does not mean for tired in English.

This for expresses excess: the speaker is so tired that it affects what they can or want to do.

Compare:

• Jeg er træt = I am tired
• Jeg er for træt = I am too tired

Because the sentence contains two separate clauses, and each clause needs its own subject.

• Jeg springer over
• jeg er for træt

So Danish repeats jeg, just as English would normally repeat I:

• I’m skipping, I’m too tired

You generally cannot leave out the second jeg here.

It sounds understandable and conversational, but in more careful writing many Danes would prefer one of these:

• Jeg springer over. Jeg er for træt.
• Jeg springer over, for jeg er for træt.
• Jeg springer over, fordi jeg er for træt.

These all make the connection clearer.

A useful thing to notice is that in for jeg er for træt, the first for means because, while the second for still means too.

So:

• for = because
• for træt = too tired

Not always. If the situation already makes it obvious, Jeg springer over is fine on its own.

It works a lot like English I’ll pass or I’m skipping when everyone already knows what is being discussed.

If you want to make the object explicit, you can say:

• Jeg springer træningen over = I’m skipping the workout
• Jeg springer mødet over = I’m skipping the meeting
• Jeg springer det over = I’m skipping it

So the object can be omitted if it is understood from context.

Yes. That is its literal meaning.

For example:

• Han springer over hegnet = He jumps over the fence

So context matters.

In Jeg springer over, jeg er for træt, the phrase is clearly idiomatic, because being too tired fits skipping something, not literally jumping over something.
