Genitive Case
Ending: -n. Used for possession (koiran nimi = dog's name), with postpositions (talon edessä = in front of the house), and as completed object (Luin kirjan = I read the book). Note: consonant gradation may change the stem.
Forgetting -n ending. Not applying consonant gradation in genitive stem. Confusing genitive and partitive for objects.
Common Error Patterns
Forgetting genitive -n
Genitive always ends in -n.
Not applying consonant gradation
Genitive uses weak grade: kirkko → kirkon, kauppa → kaupan.
Tämä on Matin auto.
This is Matti's car.
Matti → Matin (genitive -n). Possession: owner in genitive + thing owned.
Koiran nimi on Musti.
The dog's name is Musti.
Koira → koiran (genitive -n). Musti is a common Finnish dog name.
Luin kirjan loppuun.
I read the book to the end.
Kirja → kirjan (genitive = completed object). Compare: luen kirjaa (partitive = still reading).
