Questions & Answers about Glasuren har et blått mønster.
Because mønster is a neuter noun in Norwegian.
That means:
- et mønster = a pattern
- not en mønster
When an adjective describes a neuter singular noun in the indefinite form, the adjective usually gets -tt:
- blå → blått
So:
- et blått mønster = a blue pattern
If the noun were a common-gender noun, you would usually get:
- en blå bil = a blue car
This is adjective agreement.
In Norwegian, adjectives change form depending on the noun they describe. For blå, the most important patterns are:
- en blå stol = a blue chair
- et blått mønster = a blue pattern
- blå stoler = blue chairs
- det blå mønsteret = the blue pattern
So blått is the form used with a singular neuter indefinite noun.
This is one of the very common adjective patterns in Norwegian, so it is worth memorizing early.
