Swedish nouns take definite and indefinite forms depending on context. Knowing when to use each is crucial for grammar accuracy in the YKI test.

Rules:

1. Indefinite Singular: Use “en” or “ett” before a noun to indicate “a/an.”
   • Example: “En katt” (a cat), “Ett hus” (a house).
2. Definite Singular: Add suffixes like “-en” or “-et” to the noun.
   • Example: “Katten” (the cat), “Huset” (the house).
3. Indefinite Plural: Add “-ar,” “-er,” or “-n” depending on the noun group.
   • Example: “Katter” (cats), “Hus” (houses).
4. Definite Plural: Add “-na” or “-en.”
   • Example: “Katterna” (the cats), “Husen” (the houses).
