Questions & Answers about Kennslubókin útskýrir þessa reglu með mörgum góðum dæmum.

What does kennslubókin literally mean, and why is it one word?

Kennslubókin is a compound word plus a suffixed article:

• kennsla = teaching, instruction
  → kennslu- is the genitive/combining form used in compounds
• bók = book
• -in = the (definite article, feminine singular)

So:

• kennslu + bók → kennslubók = textbook (literally teaching-book)
• kennslubók + in → kennslubókin = the textbook

Icelandic usually forms things like textbook as a single compound rather than two separate words like kennslu bók.

Why is kennslubókin in this form and not something like kennslubók or kennslubókar?

Kennslubókin is:

• nominative (subject case)
• singular
• feminine
• definite (has -in, meaning the)

The verb útskýrir (explains) needs a subject in the nominative case. So we use the nominative definite form:

• nominative indefinite: kennslubók = a textbook
• nominative definite: kennslubókin = the textbook

Forms like kennslubókar would be other cases (e.g. genitive), which are not correct for the subject here.
