Questions & Answers about Sinä valitsit painikkeen, ja minä tallennan tiedoston.
How does the past tense work in valitsit?
The verb is valita (to choose or select), which is a Type 5 verb. In the past tense, Type 5 verbs use the marker -itsi-. You drop the infinitive ending, add the -itsi- marker, and then add the personal ending -t for "you", giving us valitsit.
Why do both painikkeen and tiedoston end in -n?
They are the objects of the sentence (the things being selected and saved). Because the actions are complete (you completely selected the button, and I will completely save the file), these objects take the genitive case ending -n.
The English translation says "I will save", but isn't tallennan in the present tense?
Yes! Finnish does not have a separate future tense. You use the present tense verb tallennan (I save) together with the total object tiedoston to express that you will do it and finish the action in the future.
Why is there a double "e" in painikkeen? The base word is painike.
painike is a noun that ends in -e. When you add a grammatical ending (like the -n object ending) to this specific group of words, the final -e always doubles first. So painike becomes painikkee- before adding the -n.
