Questions & Answers about Jos en pyyhi pölyä, kasvi lakastuu.
Why is pölyä in the partitive case here?
In Finnish, if the main verb is negative (like en pyyhi), the object of the sentence must be in the partitive case. Even if you were wiping all the dust, you use the partitive pölyä simply because the action does not happen.
What is the dictionary form of pyyhi, and why is the letter 'k' missing?
The dictionary form is pyyhkiä (to wipe). In a negative sentence, we use the connegative form (pyyhi). You find this by taking the 'I' form (pyyhin) and dropping the -n. Because the 'I' form ends in a closed syllable, consonant gradation occurs and the k disappears.
The English translation says 'will wither', but isn't lakastuu in the present tense?
Yes! Finnish does not have a dedicated future tense. You use the present tense for future events, and the context (like the conditional 'if' clause here) makes it clear that the withering will happen in the future.
How would I add a frequency like 'once a week' to practice this lesson's topic?
You use the quantity followed by the time period in the inessive case (-ssa or -ssä). 'Once a week' is kerran viikossa. The sentence would become: Jos en pyyhi pölyä kerran viikossa, kasvi lakastuu.
