Questions & Answers about Ég sé gleraugun hennar.
Why does hennar come after the noun instead of before it?
In Icelandic, possession is usually shown by putting the possessive word after the thing being owned. Also, notice that the noun takes the definite article attached to the end of it. So to say "her glasses", you structure it as "glasses-the her" (gleraugun hennar).
Does hennar change its ending because gleraugun is plural?
No, it doesn't! Hennar is a fixed pronoun that literally means "of her". Because it represents the owner in the genitive case, it never changes its shape to match the object being owned. It stays exactly the same whether she owns one thing or many things, and regardless of the object's gender.
How is the word gleraugun formed?
Gleraugu is a plural neuter noun meaning "glasses" (literally "glass eyes"). To say "the glasses", you add the neuter plural definite article suffix -in. When you attach -in to gleraugu, the vowels merge to become gleraugun.
What case is gleraugun in here?
It is in the accusative case because it is the direct object receiving the action of the verb sé (from sjá, meaning "to see"). However, because it is a neuter noun, it looks exactly the same in the accusative case as it does in the nominative (dictionary) case.
