Negative Sentences and the Partitive Case
In Finnish, the rule for objects in negative sentences is simple: if the verb is negative, the object is always in the partitive case.
It does not matter if the object is an uncountable mass noun or a single, countable thing. If the action doesn't happen, the object takes a partitive ending (-a, -ä, -ta, or -tä).
| I do not do work in the morning. | Minä en tee työtä aamulla. |
| We do not clean the kitchen today. | Me emme siivoa keittiötä tänään. |
Countable Objects in the Partitive
In affirmative sentences, singular countable nouns take different object cases. But when the sentence is negative, they take the partitive. For example, auto (car), ikkuna (window), and omena (apple) add an -a because the action is negated.
| You do not wash the car tomorrow. | Sinä et pese autoa huomenna. |
| They do not wash the window in the house. | He eivät pese ikkunaa talossa. |
| He does not eat the apple. | Hän ei syö omenaa. |
Daily Chores
Phrases for household chores often use mass nouns, like ruokaa (food) or pyykkiä (laundry). These are already in the partitive case, so they simply stay partitive when the sentence becomes negative.
| The woman does not wash laundry in the evening. | Nainen ei pese pyykkiä illalla. |
| The wife is not making food now. | Vaimo ei laita ruokaa nyt. |
