Questions & Answers about Hun er i godt humør når alle bidrar.

Why is it i godt humør and not på godt humør or i et godt humør?

Norwegian uses the fixed expression å være i godt humør (“to be in a good mood”). The preposition is i with many states: i form (in shape), i live (alive), i dårlig humør (in a bad mood). An article is normally not used here; i et godt humør is understandable but non-idiomatic in standard Bokmål.

Why is it godt and not god?

Because humør is a neuter noun, and adjectives agree with neuter nouns by adding -t: godt is the neuter singular form of god. The set phrase is godt humør (compare et godt spørsmål).

Could I say Hun er glad instead? What’s the difference?

Yes, but the nuance shifts. Glad = happy/pleased as a general emotion. I godt humør emphasizes being in a good or upbeat mood at that time. Both work, but they don’t always feel interchangeable.

Why use når here and not hvis?

Når = “when/whenever” (time/repeated situation). Your sentence states what regularly happens when that condition is met. Hvis (“if”) makes it more hypothetical: Hun er i godt humør hvis alle bidrar is grammatical but sounds more conditional than temporal.
