Questions & Answers about Ert þú búinn að bóka flugið?
Why do we use ert ... búinn að to say "have you booked"?
In Icelandic, the most common way to say that someone has done something is to use the verb vera (to be) plus búinn (finished) plus að and the infinitive verb. Literally, this sentence asks "Are you finished to book the flight?" but it translates to "Have you booked the flight?".
Would búinn change if I am asking a woman?
Yes! The word búinn acts like an adjective describing the subject, so it must match their gender. Since búinn is the masculine form, this sentence is asking a man. If you are asking a woman, you would use the feminine form búin: Ert þú búin að bóka flugið?
Why is the object flugið in the accusative case?
The verb bóka (to book) is an action that directly affects an object, so it requires that object to be in the accusative case. The word flug is a neuter noun, and neuter nouns always have the exact same form in the accusative case as they do in the nominative (dictionary) case.
How does the word flugið mean "the flight"?
In Icelandic, the word for "the" (the definite article) is attached to the end of the noun instead of being a separate word before it. The base noun is flug (flight), and adding the neuter suffix -ið makes it flugið (the flight).
