Learn Hardcore Icelandic: Ég kaupi bók fyrir Anna.

Kaupi is the first-person singular form of the verb kaupa in the present tense. It indicates that the speaker is performing the action (buying) right now or as a habitual action, similar to saying I buy or I am buying in English.

Why is there no indefinite article before bók, and what case is it in?

In Icelandic, indefinite articles like a or an are not used in the same way as in English. The noun bók (meaning book) appears without an article. It is in the accusative case because it is the direct object of the verb.

What role does the prepositional phrase fyrir Anna play, and why is Anna unchanged?

The phrase fyrir Anna means for Anna and indicates the beneficiary or recipient of the action. The preposition fyrir governs the dative case in Icelandic. In this context, the name Anna remains unchanged in the dative, which is common with many proper names in Icelandic.

How does the sentence structure compare to English in terms of word order?

The sentence follows a subject-verb-object order similar to English. However, Icelandic typically adheres to the verb-second (V2) rule in main clauses, meaning the verb always appears in the second position. In this case, Ég (subject) is followed by kaupi (verb), with bók (object) coming next and the prepositional phrase at the end.

Can this present-tense sentence be used to express a future action?

Yes, like in English, Icelandic can use the present tense to indicate a near-future action when the context makes the meaning clear. So, Ég kaupi bók fyrir Anna can imply that the speaker is planning to buy a book for Anna in the near future.
