Questions & Answers about Ég sit á milli gluggans og hurðarinnar.

What case are the words gluggans and hurðarinnar in, and why?

They are both in the genitive singular. The preposition milli (as in the compound preposition á milli) governs the genitive, so both nouns in the “between X and Y” phrase must be genitive: á milli X og Y with both X and Y in genitive form.

Do both nouns after á milli have to be in the genitive?

Yes. Both coordinated nouns must be in the genitive:

• Correct: á milli gluggans og hurðarinnar
• Incorrect: á milli gluggans og hurðinni / á milli gluggans og hurðina

Why are the nouns definite here (with -inn/-in), not indefinite?

Because the sentence refers to specific, contextually known items (the window and the door in the room). If you meant “a window and a door,” you would use the indefinite genitive forms:

• Definite: gluggans “of the window,” hurðarinnar “of the door”
• Indefinite: glugga “of a window,” hurðar “of a door”
