Counting Takes the Partitive

Level 1

In Finnish, numbers (2, 3, 4...) act like containers. The noun being counted is treated as a 'part' of that number, so it takes the partitive singular form.

How It Works

In English, we say 'two books' (plural). In Finnish, you say kaksi kirjaa, which literally feels like 'two of a book'.

Key Rules:

  • The 'One' Exception: The number yksi (one) is followed by the nominative singular (e.g., yksi talo).
  • Partitive Singular: Even though you are counting multiple things, the noun stays singular, just in the partitive case.
  • Adjective Agreement: If you describe the noun, the adjective must also be in the partitive singular (e.g., kaksi isoa taloa).
  • Zero: The number nolla (zero) also requires the partitive singular.

Important Note: This rule only applies when the number itself is in the basic (nominative) form. If the number changes case (e.g., 'in two houses'), the noun will match that case instead of staying in the partitive.

Examples (5)

  1. kaksi koiraa

    two dogs

    Word by Word: two dog-(partitive)

    The noun 'koira' takes the partitive ending -a after the number two.

  2. viisi euroa

    five euros

    Word by Word: five euro-(partitive)

    Commonly used with currency; 'euro' becomes 'euroa'.

  3. kolme suurta omenaa

    three large apples

    Word by Word: three large-(partitive) apple-(partitive)

    Both the adjective 'suuri' and the noun 'omena' must be in the partitive singular.

  4. nolla astetta

    zero degrees

    Word by Word: zero degree-(partitive)

    Even zero triggers the partitive singular rule.

  5. Hänellä on neljä kissaa.

    He/she has four cats.

    Word by Word: On-him/her is four cat-(partitive).

    In a 'have' sentence, the counted object follows the standard number + partitive rule.

Common Mistakes

  • Using the plural form of the noun.

    kaksi koirat
    kaksi koiraa

    Learners often use the nominative plural (-t) because English uses plurals for counting. In Finnish, you must use the partitive singular.

  • Using the partitive after the number 'one'.

    yksi taloa
    yksi talo

    After nominative 'yksi', the noun stays in the nominative singular: 'yksi talo', not 'yksi taloa'. In other cases 'yksi' and its noun agree (yhdessä talossa).

  • Forgetting to decline the adjective.

    kaksi iso taloa
    kaksi isoa taloa

    Adjectives must 'agree' with the noun. If the noun is partitive, the adjective must be partitive too.

Learn This First

To use numbers with nouns, you first need to know the basic numerals and how to form the partitive singular case, which is the specific form nouns take when counted. Vowel harmony is also required to ensure the partitive ending matches the noun's stem.
