Questions & Answers about Ring til mig når du er fremme.
Why is it Ring til mig instead of just Ring mig?
In Danish, you do not directly call a person on the phone; you call TO them. That is why the verb at ringe (to call) is paired with the preposition til when you mention who you are calling.
Why does the sentence use når for "when" instead of da?
Når is used for events in the future (like arriving later) or repeated events (like "whenever"). You only use da for a specific one-time event that already happened in the past. Since this is an instruction for the future, når is required.
The English translation says "get there", so why does the Danish sentence use er fremme which translates to "are there"?
English focuses on the action of arriving ("get there"), but Danish focuses on the state of being at your destination. Fremme means "arrived" or "at the destination", so er fremme literally means "are at the destination".
Could I use frem instead of fremme in this sentence?
No, because frem implies movement (like going forward). Because the sentence uses the verb er (are) to describe being stationary at the end of the trip, you must use the stationary form fremme.
