Using nominative instead of partitive
Check: after numbers, in negation, mass nouns, or ongoing action → partitive.
Wrong partitive ending (-a vs -ta)
After short vowel: -a/-ä. After consonant/long vowel/diphthong: -ta/-tä.
Haluan kaksi kahvia.
I want two coffees.
After numbers: kaksi + partitive (kahvia). NOT kaksi kahvit!
En ymmärrä suomea.
I don't understand Finnish.
Negation triggers partitive: suomi → suomea. Object in negative = always partitive.
Juon maitoa joka aamu.
I drink milk every morning.
Mass noun (maito = milk) takes partitive: maitoa. Uncountable = partitive.
Luen kirjaa.
I am reading a book.
Ongoing action: partitive (kirjaa). Compare: Luin kirjan = I read the book (completed, accusative).
