Questions & Answers about Hóstinn hennar er verri á nóttunni, en hún er ekki með hita.

Why does hósti become hóstinn here?

Hóstinn is hósti (cough) with the definite article attached as a suffix: -inn (masculine singular nominative).
So hóstinn hennar literally means the cough of hers → her cough.

---

Why is hennar placed after the noun instead of before it?

In Icelandic, possessive pronouns like hennar (her) commonly come after the noun: hóstinn hennar.
This is a very normal pattern, especially when the noun is definite.

---

What case is hennar, and why?

Hennar is genitive (the “of her” form). Possession in Icelandic is typically expressed with the genitive:
hóstinn hennar = the cough (of her).

Why is it er verri and not something like er verra?

Because verri is an adjective that agrees with the subject hóstinn (masculine singular nominative).

• masculine sg nom: verri
• neuter sg nom/acc would be verra, but that would match a neuter subject, not hóstinn.
