"Beskeden er skrevet på et sprog, de ikke kan forstå."

Translation: The message is written in a language that they do not understand.

I did not understand why the "ikke" word is in second position....

[deactivated user]

Because ".., de ikke kan forstå" is a dependent clause.

[skywalker735]

Also we can insert 'som' before it?

[deactivated user]

Yes, you can.

I thought that "er skrevet" should be translated as "has been written". Surely "is written" would be "bliver skrevet".

[Alice152449]

"Bliver skrevet" would be "is being written"

[Xneb]

I believe here "skrevet" is acting as an adjective rather than a verb

[Autoweird]

"Skrives" maybe?

[stikuts]

Is it wrong to write "et sprog, der de ikke kan forstå"? Or something like that with the conjunction included?

[Xneb]

"Der" doesn't really work here, but "som" is accepted in the place you wrote "der". "Der" only works as the subject of the subordinate clause

[stikuts]

tak! Jeg havde glemt forskellen mellem "der" og "som".

[Eleanor317597]

I put '...that they cannot understand'. Why is this not correct?

[uspgrade]

Dansk rhyme time. Jeg kan godt lide, hvordan sætningen ruller ud a tungen.

[Graeme859953]

It looks like cannot understand. If that is wrong, then how would you say "cannot understand"?
