Questions & Answers about Minä laitoin sieniä ja juureksia keittoon.
Why are sieniä and juureksia in the partitive plural here?
When you put an unspecified amount of something into a dish (like "some mushrooms" or "some root vegetables"), the object takes the partitive case. Because you are adding multiple mushrooms and vegetables, they must be in the partitive plural.
How do we form the partitive plural sieniä from the basic word sieni (mushroom)?
The word sieni is an older Finnish word whose stem ends in -e- (siene-). To form the plural stem, that -e- changes into the plural marker -i-, giving us sieni-. Finally, we add the partitive plural ending -ä, resulting in sieniä.
The base word for root vegetable is juures. How does it become juureksia?
For words ending in -es like juures, the basic stem ends in -ekse- (making it juurekse-). To make the plural stem, the final -e- is replaced by the plural marker -i-, giving us juureksi-. Then we just add the partitive ending -a to get juureksia.
Why does laittaa (to put) change to laitoin with only one "t"?
