Questions & Answers about Ég set tölvuna og glósubókina í töskuna.

Why do tölvuna, glósubókina, and töskuna have those endings?

They’re definite nouns in the accusative singular.

• tölvuna = tölvu (accusative of tölva, f.) + definite ending -na → the computer
• glósubókina = glósubók (accusative of glósubók, f.) + definite ending -ina → the notebook
• töskuna = tösku (accusative of taska, f., with umlaut) + -na → the bag

Rule of thumb:

• Feminine nouns ending in -a take -na in definite accusative: tölvu + na, tösku + na.
• Feminine nouns not ending in -a (like bók) take -ina: bók + ina → bókina, hence glósubókina.

Why is everything in the accusative here?

Because:

• The direct objects of setja are accusative (tölvuna, glósubókina).
• The preposition í takes accusative when it expresses motion into somewhere: í töskuna.

For location (no movement), í takes dative: í töskunni (in the bag).

When would I use the dative with í instead?
