Questions & Answers about Det finns kaffe i entrén nu.
Why is it i entrén nu instead of nu i entrén?
In Swedish, when you have both a place and a time at the end of a sentence, the place almost always comes first. This is called the Place before Time rule. Here, i entrén (in the entrance) is the place, so it goes before nu (now), which is the time.
Why do we use Det finns here to say "There is"?
Det finns literally means "It exists", and it is the standard way to say "There is" or "There are" when talking about the availability or existence of something. You wouldn't use Det är here, because that is generally used for describing things (like "It is cold") or identifying them (like "It is a coffee").
How does the word entré change to mean "the entrance"?
The word for "an entrance" is en entré. Because it is an en-word that already ends in a vowel, you just add an -n to the end to make it definite (entrén), meaning "the entrance".
