Questions & Answers about Ég drekk aldrei úr glösum.
Why is the word glösum in the dative case here?
The preposition úr (from or out of) always requires the noun that follows it to be in the dative case.
What is the base word for glösum, and why does it have an ö?
The base singular word is glas (a glass). To make it dative plural, we add the ending -um. The u in this ending triggers a common vowel shift called U-mutation, which changes the a in the root to an ö. That is why glas + -um becomes glösum.
How would I change this sentence to say 'from THE glasses'?
You would swap the bare dative plural ending -um for the definite dative plural ending -unum. The word becomes glösunum, so the phrase would be úr glösunum.
Why does aldrei (never) come after the verb drekk (drink)?
In Icelandic, the verb is almost always the second piece of information in a standard sentence. Because the subject Ég (I) takes up the first spot, the verb drekk must come second. This pushes adverbs like aldrei to the position right after the verb.
