Questions & Answers about Jeg blir lett trøtt om kvelden.

Why is it blir and not er here? What’s the difference between Jeg blir lett trøtt and Jeg er lett trøtt?

Blir in Norwegian means become / get, while er means am/is/are.

• Jeg blir lett trøtt om kvelden.
  = I get tired easily in the evening. (a process or tendency: I become tired)

• Jeg er lett trøtt om kvelden.
  This is grammatically possible, but sounds odd. It would suggest I am easily tired in the evening as a more static description, and Norwegians would almost always use blir here.

So:

• Use blir when something changes state: becomes, gets.
• Use er for a current state that is just being described, not becoming.

Examples:

• Jeg blir kald. – I’m getting cold.
• Jeg er kald. – I’m (feeling) cold.

The verb blir is in the present tense. Does that mean this is happening right now or regularly?

Norwegian present tense can express both present time and habitual/general actions, just like English simple present (I get tired easily).

In this sentence:

• Jeg blir lett trøtt om kvelden.
  is understood as a habitual statement:
  → I (generally) get tired easily in the evenings.

If you want to talk about one specific evening right now, you’d usually add a time expression like:

• I kveld blir jeg sikkert trøtt tidlig. – Tonight I’ll probably get tired early.
