Questions & Answers about Nóttin er rólegri í sveitinni.
They are:
- nóttin → nótt (night)
- er → vera (to be)
- rólegri → rólegur (quiet, calm)
- sveitinni → sveit (countryside, rural area, district)
This is useful because Icelandic words change form a lot, so the form you see in a sentence is often not the dictionary form.
Because Icelandic usually puts the definite article (the) at the end of the noun instead of using a separate word.
So:
- nótt = night
- nóttin = the night
That -in ending is the suffixed definite article here.
It is nominative singular.
Why? Because nóttin is the subject of the sentence: it is the thing that is something. In sentences with vera (to be), the subject is normally in the nominative.
