Learn Danish: Det glæder mig at borgergruppen får borgmesteren til at lytte. - It pleases me that the citizens' group is making the mayor listen.

This uses an impersonal psychological construction where det acts as a dummy subject (meaning "it"). While jeg er glad for at (I am glad that) is perfectly correct and very common in everyday Danish, using det glæder mig (it pleases me) shifts the grammatical focus onto the event that is causing the happiness. It is also slightly more formal and elegant.

To translate "making the mayor listen", why is the verb får used instead of gør?

A direct translation of "make someone do something" using gør does not work in Danish. Instead, Danish uses the causative construction at få nogen til at gøre noget, which literally translates to "to get someone to do something". Therefore, får borgmesteren til at lytte is the grammatically correct way to express that the group is compelling the mayor to listen.

The English translation says "the citizens' group", so why isn't there a possessive -s attached to borger?

While English uses a possessive form ("citizens'") to describe a group made up of citizens, Danish creates a single compound noun: borgergruppen. You do not use a possessive -s because the citizens do not literally "own" the group; rather, borger acts as a modifier telling you what kind of group it is.

In the compound word borgergruppen, why does only the end of the word have a definite article?
