Level A1
There are four cases in Icelandic. The second case in the declension table is known as the “accusative case”.[a] It shows that the word is having something done to it.
The helper word you use to force a word into the second case is „um“ (“about”).

Things that cause the second case

The following prepositions always cause the second case:
  • um (about)
  • gegnum (through)
  • kringum (around)
And these prepositions can either cause the second or the third case depending on context (click here to see the difference):
  • á (onto)
  • eftir (after)
  • fyrir (for)
  • í (into)
  • með (with)
  • undir (under)
  • við (by)
  • yfir (over)
The majority of verbs cause the second case. Among common verbs that do so are:
  • að eiga (to own)
  • að hafa (to have)
  • að tala (to speak)
  • að geta (to be able to)
  • að vilja (to want)
