Questions & Answers about Reititin jumiutuu kerran viikossa, joten käynnistän sen aina uudelleen.
Why do we use joten here instead of siksi?
Joten is a relative conjunction that connects two clauses where the second is a direct consequence of the first, just like the English word "so". If you used the adverb siksi (therefore/for that reason), you would typically break this into two sentences: Reititin jumiutuu kerran viikossa. Siksi käynnistän sen aina uudelleen.
Why is the time period in the inessive case (viikossa)?
When expressing how often something happens within a specific time period, Finnish uses the inessive case (-ssa or -ssä). Kerran viikossa translates to "once a week". Similarly, "twice a year" would be kaksi kertaa vuodessa.
Why is the object sen and not the partitive sitä?
The verb käynnistää (to start) here refers to a total, completed action—you are completely restarting the router. Because the action is viewed as a whole, the object takes the genitive-like accusative form sen. If the restarting process was ongoing or incomplete, you would use the partitive sitä.
How is the word "restart" formed in this sentence?
Finnish doesn't have a single everyday verb for "restart" in this context. Instead, it pairs the verb käynnistää (to start or boot up) with the adverb uudelleen (again or anew). Notice that they remain separate words, and uudelleen is often placed at the end of the clause.
