Learn Icelandic: Vistar þú góðu vefsíðurnar?

Because the noun it describes, vefsíðurnar (the websites), is definite (it has the article attached). When an adjective comes before a definite noun, it must use the weak declension. The great thing about weak plural adjectives is that they end in -u across all genders and almost all cases!

How is the word vefsíðurnar put together?

The base word is vefsíða, a feminine noun meaning website. Its plural is vefsíður (websites). Because we are saying the websites, we add the plural feminine definite article -nar to the end, giving us vefsíðurnar.

What case is góðu vefsíðurnar in?

It is in the accusative case because it is the direct object being saved. For feminine plural nouns, the accusative form is exactly the same as the nominative (subject) form. As mentioned, the weak adjective góðu also stays the same here.

Does the verb vista mean to save in all situations?
