Questions & Answers about Bókunarstaðfestingin kom í dag.

How is bókunarstaðfestingin built up?

It is a compound noun made of:

• bókun = booking, reservation
• staðfesting = confirmation
• -in = the definite article the

So the core idea is booking-confirmation-the = the booking confirmation.

More precisely, the first part appears as bókunar-, not just bókun, because Icelandic very often uses a genitive form inside compounds. That gives the sense of confirmation of a booking.

So:

• bókunarstaðfesting = booking confirmation
• bókunarstaðfestingin = the booking confirmation

Why does it end in -in?

Because Icelandic usually puts the definite article onto the noun itself, instead of using a separate word like English the.

Here:

• bókunarstaðfesting = booking confirmation
• bókunarstaðfestingin = the booking confirmation

This is very common in Icelandic. So instead of a separate article before the noun, you often see a suffix attached to the end.

Why is it bókunar- and not just bókun-?
