Definite dative nouns (-num, -nni, -nu)

In the previous lesson, you learned that prepositions indicating a static location (í, á) or origin (frá) require the dative case.

When a noun has "the" attached to it (a definite noun), its dative ending changes based on its gender.

Neuter Definite Nouns (-nu)

For neuter nouns, the definite dative ending is -nu (most often seen as -inu).

  • eldhúsið (the kitchen) becomes eldhúsinu.
  • gólfið (the floor) becomes gólfinu.
The man is inside the kitchen.
Maðurinn er inni í eldhúsinu.
My dog sits on the floor.
Hundurinn minn situr á gólfinu.

Masculine Definite Nouns (-num)

For masculine nouns, the definite dative ending is -num (taking the form -inum or just -num).

  • diskurinn (the plate) becomes diskinum.
  • veitingastaðurinn (the restaurant) becomes veitingastaðnum.
The cake is on the plate in the kitchen.
Kakan er á diskinum í eldhúsinu.
He comes from the restaurant.
Hann kemur frá veitingastaðnum.

Feminine Definite Nouns (-nni)

For feminine nouns, the definite dative ending is -nni (taking the form -unni or -inni).

  • vinnan (the work) becomes vinnunni.
  • taskan (the bag) becomes töskunni.
  • skálin (the bowl) becomes skálinni.

Notice how the a in taskan changes to an ö in töskunni—the u in the dative ending triggers this vowel shift!

The woman is not at work.
Konan er ekki í vinnunni.
The key is in the bag.
Lykillinn er í töskunni.
The fish is in the bowl.
Fiskurinn er í skálinni.
