Questions & Answers about Kunkin täytyy sekoittaa pakka yhden kerran.
Why is kunkin in the genitive case here instead of the basic form kukin?
The verb täytyy (must / has to) is a necessity verb. In Finnish, sentences expressing necessity require the subject (the person who has to do something) to be in the genitive case. So, the basic form kukin becomes kunkin.
How exactly is the word kunkin formed from kukin?
When inflecting words that end with the suffix -kin, the case ending is inserted before the suffix. The base pronoun is kuka (or ku- in this form). To make it genitive, you add the -n ending to the base, and then attach -kin at the very end: ku + n + kin = kunkin.
Why is the object pakka (the deck) in the basic nominative case rather than the genitive pakan?
Normally, an object representing a whole, completed action takes the genitive ending -n. However, there is a special rule for necessity verbs like täytyy: their total objects are always in the basic nominative case without an ending.
Why does the phrase yhden kerran (one time) end in -n?
This is the accusative case, which is used for expressions of time, amounts, or frequency to show an action is done fully. For singular words, this accusative form looks exactly like the genitive, ending in -n.
