Questions & Answers about Han skrev en bok om kriget.
Why doesn't skrev have a past tense ending like -de or -te?
Skrev comes from the verb skriva (to write). It belongs to the group of strong verbs that do not take a suffix in the past tense. Instead, they change their root vowel. Here, the i in skriva changes to e to become skrev.
What is the base form of the word kriget?
The base form is ett krig (a war). Because it is an ett-word, it takes the definite ending -et to mean "the war" (kriget).
I remember om meaning "if". Why is it used here?
The preposition om has a few different meanings depending on the context. When used with actions like writing, reading, or talking, it translates to "about". So en bok om kriget simply means "a book about the war".
Just to refresh my memory, what is the plural of bok?
Bok is an irregular en-word. If he wrote multiple books, you would use the plural form böcker. The vowel changes from o to ö and it takes the -er ending.
