Hun finder fjernbetjeningen, tænder fjernsynet og sukker, fordi skærmen begynder at blinke.

Because Danish verbs do not change for person the way English verbs sometimes do. In the present tense, the same form is used with I, you, he/she/it, we, and they.

So:

• jeg finder = I find
• du finder = you find
• hun finder = she finds
• vi finder = we find

The present tense is often formed with -r, which is what you see in finder, tænder, sukker, and begynder.

In Danish, the definite article is usually attached to the end of the noun instead of being a separate word like the in English.

So:

• en fjernbetjening = a remote control

• fjernbetjeningen = the remote control

• et fjernsyn = a television

• fjernsynet = the television

• en skærm = a screen
• skærmen = the screen

A very common pattern is:

• common gender noun: -en
• neuter noun: -et

So English the is often built into the noun in Danish.

You have to know the noun’s grammatical gender.

If the noun is a common gender noun, it usually takes:

• indefinite: en
• definite: -en

If the noun is a neuter noun, it usually takes:

• indefinite: et
• definite: -et

In this sentence:

• fjernbetjening is common gender → en fjernbetjening, fjernbetjeningen
• fjernsyn is neuter → et fjernsyn, fjernsynet
• skærm is common gender → en skærm, skærmen

This is something learners usually need to memorize along with each noun.

Because at blinke is an infinitive, like to blink in English.

In the sentence:

• Hun finder ... tænder ... og sukker ...
  these are finite present-tense verbs: finds, turns on, sighs

• begynder at blinke
  here begynder means begins, and at blinke is the infinitive to blink

So Danish often uses:

• begynde at + infinitive = begin to + verb

Examples:

• Hun begynder at grine = She begins to laugh
• Skærmen begynder at blinke = The screen begins to blink

Yes, it is a very common Danish structure.

at begynde often takes at + infinitive:

• begynde at læse = begin to read
• begynde at tale = begin to speak
• begynde at blinke = begin to blink

So if you learn begynde at + verb, you can reuse it in many situations.

Because Danish, like English, does not need to repeat the subject when the same subject continues across coordinated verbs.

So:

• Hun finder fjernbetjeningen, tænder fjernsynet og sukker

means:

• She finds the remote control, turns on the television, and sighs

English works the same way. You could repeat the subject, but it would usually sound unnecessary:

• Hun finder fjernbetjeningen, hun tænder fjernsynet, og hun sukker

That is grammatical, but less natural here.

Yes, tænde originally relates to lighting or switching on, but in modern Danish it is very commonly used for turning on devices.

So:

• tænde lyset = turn on the light
• tænde fjernsynet = turn on the television
• tænde computeren = turn on the computer

The opposite is usually slukke:

• slukke lyset = turn off the light
• slukke fjernsynet = turn off the television

So even if it may feel a little like light historically, in normal Danish it is just the standard verb for switching something on.

fjernsynet means the television / TV set, while skærmen means the screen.

So the sentence first talks about turning on the TV as a device, and then it focuses on one part of it:

• tænder fjernsynet = turns on the television
• skærmen begynder at blinke = the screen begins to flicker/blink

This is natural, because the screen is the part that shows the problem.

Yes, it can look confusing.

In this sentence, sukker is the present tense of the verb at sukke, meaning to sigh.

So:

• hun sukker = she sighs

But sukker can also be the noun sugar in other contexts:

• Jeg vil have sukker i kaffen = I want sugar in the coffee

The meaning depends on context. Here, after hun, it is clearly a verb.

Because fordi introduces a subordinate clause: because the screen begins to blink.

Danish punctuation often separates clauses clearly with commas, especially when a main clause is followed by a subordinate clause.

So the sentence has:

• main clause: Hun finder fjernbetjeningen, tænder fjernsynet og sukker
• subordinate clause: fordi skærmen begynder at blinke

That is why you see the comma before fordi.

Because after fordi, Danish uses subordinate clause word order, where the subject normally comes before the verb.

So:

• fordi skærmen begynder at blinke
  = because the screen begins to blink

This is the normal pattern:

• fordi + subject + verb

Examples:

• fordi hun er træt = because she is tired
• fordi jeg ikke forstår det = because I do not understand it

A learner often notices Danish V2 word order in main clauses, but subordinate clauses like those with fordi usually go back to a more straightforward subject-verb order.

Because fjernsynet is the direct object itself.

• tænder fjernsynet = turns on the television

English also does this:

• She turns on the television

You only need it if you are replacing the noun:

• Hun tænder det = She turns it on

So there is nothing missing in the Danish sentence.

Often yes, but the exact feel depends on context.

For a screen, blinke can mean:

• blink
• flash
• flicker

So skærmen begynder at blinke could be understood as the screen starting to blink or flicker. In everyday use, that sounds very natural for a technical problem.

If you used indefinite nouns, it would be:

• Hun finder en fjernbetjening, tænder et fjernsyn og sukker, fordi en skærm begynder at blinke.

But that sounds less natural in this context, because the sentence seems to refer to specific things:

• the remote control
• the television
• the screen

So the definite forms are the natural choice.

Here are the most useful base forms:

• hun = she
• at finde → finder = find / finds
• en fjernbetjening → fjernbetjeningen = remote control / the remote control
• at tænde → tænder = turn on / turns on
• et fjernsyn → fjernsynet = television / the television
• at sukke → sukker = sigh / sighs
• fordi = because
• en skærm → skærmen = screen / the screen
• at begynde → begynder = begin / begins
• at blinke = to blink

This is a good way to study the sentence: learn both the base form and the form actually used.
