Questions & Answers about Ég sker peru smátt og set hana í hafragrautinn.
Skera is the dictionary form, meaning to cut.
In the sentence, the verb has to match ég (I), so it becomes the 1st person singular present tense:
- að skera = to cut
- ég sker = I cut
- þú skerð = you cut
- hann/hún sker = he/she cuts
So ég sker is the normal finite verb form here.
Because pera is the direct object of sker, and Icelandic marks direct objects with case.
The noun is:
- nominative: pera
- accusative: peru
Since the sentence says I cut a pear, pear is the thing being cut, so Icelandic uses the accusative: peru.
