Questions & Answers about Uppskeran er mikil.
Because Icelandic usually puts the definite article on the end of the noun instead of using a separate word like English the.
- uppskera = harvest
- uppskeran = the harvest
So -an here is part of the definite form of the noun.
The dictionary form is uppskera.
That is the indefinite nominative singular form, the form you would normally look up in a dictionary. It is a feminine noun.
Because Icelandic adjectives must agree with the noun they describe in gender, number, and case.
Here:
- uppskeran is feminine
- singular
- nominative (because it is the subject)
So the adjective must also be feminine singular nominative:
- masculine: mikill
- feminine: mikil
- neuter: mikið
That is why the sentence uses mikil.
