Partitive for Uncountable Things

Level 1

In Finnish, when you talk about substances like water, bread, or money in an indefinite way, you use the partitive case. It often translates to 'some' in English.

How It Works

The partitive case is essential for handling 'mass nouns'—things you can't easily count as individual units, like liquids, powders, or abstract concepts. Mass nouns commonly have a singular mass reading, but take different cases according to their role: maito, maidon, maidossa, maitoa. Plurals often refer to kinds or portions.

1. Indefinite Quantity vs. Specific Subject
When a mass noun is the subject of a sentence, its case depends on whether it is specific or an unspecified quantity. If you are talking about a specific batch of a substance, use the nominative: Maito on pöydällä (The milk is on the table). If you are stating that some unspecified amount exists somewhere, use the partitive: Pöydällä on maitoa (There is [some] milk on the table).

2. Syntactic Roles
Mass nouns appear in the partitive in several common situations:

  • As an Object: When you are doing something to an unspecified amount of a substance or the action is incomplete (Syön leipää - I am eating [some] bread). However, if you perform a bounded, completed action on a specific, total quantity, use a total object (Syön leivän - I will eat the loaf of bread). Here bread is construed as a bounded countable unit, a loaf, rather than an indefinite substance.
  • After Negation: Negation forces the partitive specifically for objects and existential/possessive subjects (Minulla ei ole rahaa - I don't have [any] money). However, specific subjects stay in the nominative even in negative sentences (Maito ei ole pöydällä - The milk is not on the table).
  • With Adjectives: When you describe a mass noun using 'olla' + adjective, the adjective must be in the partitive (Maito on kylmää - The milk is cold).
  • With Quantities: While all nouns take the partitive after numbers (except one), mass nouns are typically counted using measure words. The measure word takes the partitive after the number, and the mass noun itself also stays in the partitive (kaksi kiloa sokeria - two kilos of sugar; paljon sokeria - a lot of sugar).
  • Materials and Substances: A mass noun predicate identifies a substance, Tämä on maitoa (this is milk), or says what material something is made of (Sormus on kultaa - The ring is [made of] gold).
  • Partitive Verbs: The ordinary basic uses of verbs such as rakastaa and etsiä take the object into the partitive case, regardless of whether it is a mass noun or a specific quantity (Rakastan maitoa - I love milk).

3. Choosing the Ending
The ending depends on vowel harmony and the word stem. Words with back vowels (a, o, u) take -a / -ta / -tta, while words with front vowels (ä, ö, y) take -ä / -tä / -ttä. If a word contains only neutral vowels (e, i), it takes the front vowel endings (e.g., vesi → vettä, lehti → lehteä). Direct-gradation words keep the strong stem in the singular partitive: keitto → keittoa. Other types have their own stem pattern, such as rikas → rikasta compared with rikkaan.

  • -a / -ä: Used for many vowel-stem words (e.g., maito → maitoa).
  • -ta / -tä: Used for words ending in two vowels (long vowels or diphthongs) or a consonant (e.g., maa → maata, tie → tietä, mies → miestä).
  • -tta / -ttä: Used for the hame-type class of -e words, not every word spelled with final e (e.g., sade → sadetta). An important exception for mass nouns is vesi (water), which takes the -tta/-ttä ending to become vettä.

Examples (6)

  1. Juon kahvia.

    I am drinking coffee.

    Word by Word: I drink coffee-[partitive].

    Coffee is a mass noun; since I'm drinking an indefinite amount, it takes the partitive ending -a.

  2. Kaapissa on sokeria.

    There is sugar in the cupboard.

    Word by Word: Cupboard-in is sugar-[partitive].

    In an existential clause ('there is'), mass nouns like sugar must be in the partitive to indicate an unspecified amount.

  3. Maito on pöydällä.

    The milk is on the table.

    Word by Word: Milk is table-on.

    When a mass noun is the specific subject of a sentence (the milk, not some milk), it takes the nominative case, not the partitive.

  4. Maito on kylmää.

    The milk is cold.

    Word by Word: Milk is cold-[partitive].

    When describing a mass noun with an adjective, the adjective must be in the partitive case.

  5. Minulla ei ole rahaa.

    I don't have money.

    Word by Word: On-me not is money-[partitive].

    In a negative possessive clause, the existential subject rahaa (money), not an ordinary transitive object, is partitive.

  6. Ostan kaksi kiloa sokeria.

    I am buying two kilos of sugar.

    Word by Word: I-buy two kilos-[partitive] sugar-[partitive].

    For pure mass nouns, measure words like 'kiloa' are used after numbers. Both the measure word and the mass noun take the partitive.

Common Mistakes

  • Using the nominative (basic form) for a mass noun object.

    Minä juon vesi.
    Minä juon vettä.

    In English, we say 'I drink water,' but in Finnish, you cannot use the dictionary form 'vesi' for an indefinite amount of liquid. You must use the partitive 'vettä'.

  • Forgetting the partitive in negative sentences.

    En osta leivän.
    En osta leipää.

    Even if you were thinking of a specific loaf, negation always forces the partitive.
