Questions & Answers about Ég hlakka til að opna gjöfina um jólin.
The lesson says hlakka til requires the genitive case. Why isn't there a genitive word after it here?
Because hlakka til is followed by an action (að opna), not a noun or pronoun. If you were looking forward to a thing, like Christmas, you would use the genitive noun (Ég hlakka til jólanna). But since you are looking forward to doing something, you just use the infinitive verb (að + verb), which doesn't take a case.
Why is it gjöfina and not just gjöf?
Gjöfina means 'the gift'. It is the feminine noun gjöf (gift) with the definite article -ina (the) attached to the end. It is in the accusative case because it is the direct object receiving the action of the verb opna (to open).
Why is the preposition um used here for 'at'?
In Icelandic, the preposition um (which often means 'about' or 'around') is the standard word used with holidays and seasons to mean 'at' or 'during' that time. When used for time, um always forces the following word into the accusative case.
Is the word for Christmas (jól) a plural word?
