Questions & Answers about Hún gleður ömmu sína með litlu símtali á hverjum sunnudegi.
Gleður is the 3rd person singular present tense of að gleðja.
Because the subject is hún = she, Icelandic uses the matching finite verb form:
- að gleðja = to make happy, to gladden
- hún gleður = she makes happy / she gladdens
So gleðja is the dictionary form, but gleður is the form that fits this sentence.
Because amma is the direct object of gleður, it has to be in the accusative case.
The noun declines like this in the singular:
- amma = nominative
- ömmu = accusative
So:
- Hún gleður ömmu sína = She makes her grandmother happy
Even though ömmu can also be the same form in other cases, its job here is accusative object.
