Questions & Answers about Kafarinn lagaði kafbátinn heilan dag.
Why is heilan dag in the accusative case without a preposition like "í" (for)?
This is the Accusative of Extent. When expressing the duration of an action (how long it took), Icelandic often uses a "bare" accusative noun phrase instead of a preposition. Here, heilan dag directly acts as an adverb meaning "for a whole day."
The sentence has two accusative noun phrases in a row: kafbátinn and heilan dag. Is that normal?
Yes! Even though both are in the accusative, they serve different grammatical roles. Kafbátinn is the direct object receiving the action of the verb að laga (to repair). Heilan dag is an adverbial time phrase. Icelandic syntax comfortably allows an object and a duration phrase to sit side by side.
I see kafarinn (the diver) and kafbátinn (the submarine) share the same root. What is it?
They both come from the root kaf, which relates to diving or being underwater. The verb að kafa means "to dive." Therefore, a kafari is a diver, and a kafbátur (literally "dive-boat") is a submarine.
Why does the adjective heill (whole) become heilan here?
Adjectives must agree with the noun they modify in gender, number, and case. Because this sentence uses the Accusative of Extent, the masculine singular noun dagur (day) takes its accusative form, dag. The adjective heill follows suit, taking the masculine singular accusative ending -an to become heilan.
