Questions & Answers about Nóttin er löng og köld.
Yes. Icelandic usually marks definiteness by adding a suffix to the noun. -in is the nominative singular feminine definite ending, so Nóttin means the night. Without it, nótt means “a night” or just “night” (indefinite). A few other common forms:
- Accusative singular definite: nóttina
- Dative singular definite: nóttunni (e.g., á nóttunni = “at night”)
- Genitive singular definite: næturinnar (genitive sg is nætur: e.g., til nætur = “tonight”)
