Questions & Answers about Værelset er stille om aftenen.

What does the -et at the end of værelset mean?

The -et is the definite article attached to a neuter noun.

• et værelse = a room
• værelset = the room

In Danish, the definite article is usually a suffix on the noun instead of a separate word like English the.

Why is it om aftenen and not i aftenen?

With parts of the day (morning, evening, night) you usually use om to express “in the …” in a general or habitual sense:

• om morgenen = in the morning / in the mornings
• om aftenen = in the evening / in the evenings

i aftenen is not idiomatic in standard Danish. For a specific evening (tonight) you say i aften, not om aftenen.

Does om aftenen mean every evening or just in the evening (today)?

By default, om aftenen is understood as habitual or general:

• Værelset er stille om aftenen.
  → The room is (usually) quiet in the evening(s) / at night.

If you meant this specific evening (tonight), you would normally say:

• Værelset er stille i aften.
  → The room is quiet tonight.

What is the difference between stille and rolig? Can I use both here?
