Learn Swedish: Trasiga böcker lagas ofta med lim eller tejp. - Broken books are often repaired with glue or tape.

In Swedish, the preposition med is used to show the tool or material you use to perform an action. Here, glue (lim) and tape (tejp) are the specific materials being used to fix the books, so we use med just like the English word with.

Why does the verb laga end with an -s here to make lagas?

The -s at the end of lagas creates the passive voice. Instead of saying someone actively repairs the books, it translates to the books are repaired. You will see this s-passive form used very often for general statements where it does not matter who is actually doing the repairing.

Why is the adjective written as Trasiga instead of Trasig?

Because it is describing böcker, which is a plural noun. In Swedish, adjectives must match the noun they describe. Since we are talking about multiple books, the basic adjective trasig gets an -a added to the end to become the plural form trasiga.

The basic word for book is bok, so why is it spelled böcker here?
