"Her existence is necessary, because I can't live without her."

Translation: Hendes eksistens er nødvendig, for jeg kan ikke leve uden hende.

[FyodorPavlovich]

Hvorfor kan vi ikke bruge ,,fordi'' i stedet af ,,for''?

[deactivated user]

Den kan man godt. Så bliver leddet efter bindeordet til en bisætning.

Hendes eksistens er nødvendig, for jeg kan ikke leve uden hende.

Hendes eksistens er nødvendig, fordi jeg ikke kan leve uden hende.

Notice the position of ikke.

[AprilKoskinen]

Why isn't "for" considered a conjunction (and then placing ikke after the subject?)

Thanks for the tip viktorbluhme. I have never known this. Would it be asking too much for an elaboration on the difference between the two versions?

[deactivated user]

You can simply look at the definitions of the two.

fordi: conjunction. Used to introduce a subordinate clause that expresses a logical reason or a cause in general.

for: conjunction. Used to express that the following is to be understood as an explanation of the previous statement. Grammar: for +MAIN CLAUSE

Thanks for your fast reply viktorbluhme. Although I understand the definitions for "for" and "fordi", I can find no reference for the difference between "kan ikke" and "ikke kan", in "Den Danske Ordbog". Could you elaborate further, please?

[deactivated user]

It has nothing to do with vocabulary. It is simply very basic Danish sentence construction.

In main clauses, the adverb comes after the subject and the verb.

In subordinate clauses, the adverb comes between the subject and the verb.

Tak; det hjælper. Jeg vidste ikke at positionen af 'ikke' ændrede sig.

[Mootje369]

This is so romantic

I wrote "Hendes eksistens er nødvendig fordi jeg kan ikke leve uden hende". "For" rather than "fordi" in Danish, what Duolingo is asking for, would be "for" in English and not "because"
