Spoken Numbers

Level 2

In everyday spoken Finnish (puhekieli), the numbers 1–10 are often shortened to make speech faster and more fluid. For example, yksi becomes yks and kaksi becomes kaks.

How It Works

While formal Finnish (kirjakieli) uses full forms like yksi and kahdeksan, spoken Finnish uses shortened versions to reduce syllable count.

Common Shortening Patterns:

  • Dropping the final -i: Applies to 1, 2, 5, and 6.
    yksi → yks, kaksi → kaks, viisi → viis, kuusi → kuus. While kolme (3) and neljä (4) often stay the same, they can shorten to kol and nel during rapid counting sequences or when forming tens (e.g., kolkyt).
  • Consonant Simplification: Internal sounds change.
    seitsemän → seittemä(n) (the cluster -ts- simplifies to a double -tt-)
    kahdeksan → kaheksa(n) (the -d- disappears)
    yhdeksän → yheksä(n) (the -d- disappears)
  • Dropping the final -n: Numbers ending in -n (7, 8, 9, 10) often lose it in casual speech. Kymmenen (10) is usually shortened to kymmene or the noun form kymppi.
  • Shortening Teens and Tens: The suffix -toista is often shortened to -toist (e.g., ykstoist). The suffix -kymmentä is shortened to -kyt or -kytä. Note that because these are compound words, the suffix -kytä always keeps its front vowels (y, ä) and does not change to match back-vowel roots (e.g., kaheksakytä).
  • Colloquial Names and Ordinals: For bus numbers or grades, digits are often called seiska (7), kasi (8), and ysi (9). The ordinal numbers for 'first' and 'second' are almost always eka and toka.

Usage Note: Even when using spoken forms, the noun following the number must still follow the partitive rule (e.g., viis euroa).

Examples (4)

  1. Mul on yks kissa ja kaks koiraa.

    I have one cat and two dogs.

    Word by Word: At-me is one cat and two dogs.

    Uses 'yks' and 'kaks' instead of 'yksi' and 'kaksi'. Note that 'koiraa' is in the partitive singular.

  2. Se maksaa viis euroo.

    It costs five euros.

    Word by Word: It costs five euros.

    In speech, both the number (viis) and the currency (euroo) are shortened.

  3. Oota kaheksan minuuttia.

    Wait eight minutes.

    Word by Word: Wait eight minutes.

    Demonstrates the spoken form 'kaheksan' where the 'd' from 'kahdeksan' is dropped.

  4. Bussi seittemän tulee nyt.

    Bus seven is coming now.

    Word by Word: Bus seven comes now.

    Uses 'seittemän' instead of the formal 'seitsemän'.

Common Mistakes

  • Using spoken numbers in formal writing.

    Hakemuksessa on viis liitettä.
    Hakemuksessa on viisi liitettä.

    Spoken forms like 'viis' should be avoided in formal documents, exams, or professional emails; use the full 'viisi' instead.

  • Confusing spoken numerals with fast-counting forms.

    Mulla on koo lasta.
    Mulla on kolme lasta.

    Forms like 'yy, kaa, koo, nee' are only for rhythmic counting (like hide-and-seek). In sentences, use 'yks, kaks, kolme, neljä'.

Learn This First

To understand spoken numerals, you first need to be familiar with the standard written numbers 1-10. It is also helpful to understand how Finnish sounds work, particularly vowel and consonant length, as spoken forms are essentially phonetic abbreviations of the formal words.
