Questions & Answers about Bilen er blå.
Use the indefinite article en before the noun:
en bil = “a car.”
In Bokmål, bil is a common-gender noun (often called masculine). That means:
• Indefinite singular: en bil (“a car”)
• Definite singular: bil + en → bilen (“the car”)
Invert the verb and subject:
Er bilen blå? = “Is the car blue?”
Use the common-gender pronoun den. For example:
Bilen er blå. Den er nyvasket.
= “The car is blue. It is freshly washed.”
Attach the possessive after the noun in its definite form:
bilen min er blå = “my car is blue.”
Definite plural of bil is bilene, so:
Bilene er blå. = “The cars are blue.”
(General statement “Cars are blue” would be Biler er blå.)
Use the demonstrative den + adjective + definite noun suffix:
den blå bilen = “the blue car.”
(Note: attributive adjectives in a definite phrase normally take -e, but blå is one of the few adjectives that stays the same here.)
