Learn Danish: Lægens nye bil er dyr. - The doctor's new car is expensive.

The base word is læge (doctor). To say "the doctor", we add the definite ending -n to make lægen. Then, just like in English, we add an -s to show possession (the doctor's), making it lægens.

Why is the word for "new" written as nye instead of ny when "car" is singular?

In Danish, adjectives get an -e at the end when they come after a possessive word like lægens (the doctor's), min (my), or hans (his). Even though it's only one car, the possessive triggers this adjective form nye.

Since it is a specific car, why is it just bil and not the definite form bilen?

When you use a possessive word (like lægens) in Danish, the noun that follows must stay in its basic, indefinite form. So we say lægens nye bil, never lægens nye bilen.

Why doesn't dyr have an -e at the end like nye does?

dyr (expensive) comes after the verb er (is) to describe the car, rather than being placed directly in front of the noun. In this position, it only needs to match the gender of the noun. Since bil is a singular "en" word, dyr stays in its basic form without an -e.
