Questions & Answers about Íbúðin er stærri en herbergið.
Icelandic usually attaches the definite article (the) to the end of the noun instead of putting a separate word before it.
- íbúð = a flat / an apartment
íbúðin = the flat / the apartment
- ending -in = feminine singular definite article in the nominative case
- herbergi = a room
- herbergið = the room
- ending -ið = neuter singular definite article in the nominative/accusative
So the sentence literally has íbúð-in (apartment-the) and herbergi-ð (room-the) instead of a separate the.
The dictionary form is the indefinite nominative singular:
íbúð – feminine noun, an apartment
- definite nominative singular: íbúðin (the apartment)
herbergi – neuter noun, a room
- definite nominative singular: herbergið (the room)
When you look these words up in a dictionary, you’ll find íbúð and herbergi, not the forms with the article attached.
