Colon Before an Ending

Level 6

In Finnish, when you attach a case ending to something that isn't a standard word—like a number (3), an abbreviation (EU), or a symbol (%)—you must use a colon (:) as a bridge.

How It Works

The colon (kaksoispiste) is a mandatory orthographic tool in Finnish used to bridge the gap between symbols/digits and case endings, or between written and spoken forms. Use it in these scenarios:

  • Digits and Symbols: When writing numbers as figures or using symbols like %. Example: 3:ssa (in three), %:n (of the percent).
  • Initialisms: Abbreviations read letter-by-letter (like EU, YK, USA) always require a colon: EU:ssa.
  • Acronyms vs. Contractions: Acronyms read as words (like Nato or Kela) do not use a colon. Contractions (like klo for kello) only omit the colon if the abbreviation ends in the same letter as the full word (e.g., kloon).
  • Pronunciation Mismatch: This is vital for foreign names. If a word ends in a consonant in writing but a vowel in speech (or vice versa), use a colon. Example: Bordeaux:hun (pronounced 'bordoohon') or show:n (pronounced 'shoun').
  • Single Letters: When discussing the letter itself, e.g., A:sta B:hen.

Crucial Rule: Vowel Harmony
The case ending must match the vowel harmony of the spoken word. For example, EU is pronounced ee-uu. Since 'u' is a back vowel, we use EU:ssa (back vowel ending).

Ordinal Numbers
When using ordinal numbers in digits, the colon is followed by the ordinal marker (usually :s or :nne-) before the case ending, e.g., 3:s (3rd) or 3:nnessä (in the 3rd).

Examples (6)

  1. Hän asuu USA:ssa.

    He/she lives in the USA.

    Word by Word: He/she lives USA-in.

    USA is an initialism read letter-by-letter (uu-äs-aa), so a colon is mandatory before the case ending.

  2. Kävin Bordeaux:ssa viime kesänä.

    I visited Bordeaux last summer.

    Word by Word: I visited Bordeaux-in last summer.

    The written form ends in a consonant (x), but the spoken form ends in a vowel (o). A colon is required to bridge this difference.

  3. Nato päätti asiasta eilen.

    Nato decided on the matter yesterday.

    Word by Word: Nato decided matter-about yesterday.

    Acronyms read as words (like Nato or Kela) do not use a colon; they are treated like regular nouns.

  4. Olen töissä 8:sta 16:een.

    I am at work from 8 to 16 (4 PM).

    Word by Word: I am at work 8-from 16-to.

    Colons are used to attach the elative (-sta) and illative (-een) endings to digits.

  5. Katsoin uuden show:n.

    I watched the new show.

    Word by Word: I watched new show-n.

    The word 'show' ends in a consonant (w) in writing but a vowel (ou) in speech, requiring a colon before the genitive -n.

  6. YK:n päämaja on New Yorkissa.

    The UN headquarters is in New York.

    Word by Word: UN's headquarters is New York-in.

    YK (Yhdistyneet kansakunnat) is an initialism read as letters (yy-koo), so it takes a colon.

Common Mistakes

  • Omitting the colon entirely.

    Asun EUssa.
    Asun EU:ssa.

    In Finnish, you cannot attach a case ending directly to an abbreviation or digit; the colon is grammatically required.

  • Choosing the ending based on the written letter instead of pronunciation.

    EU:ssä
    EU:ssa

    Even though 'E' is a front vowel, the abbreviation is pronounced 'ee-uu'. The last sound 'uu' requires the back vowel ending -ssa.

  • Using a colon for acronyms pronounced as words.

    NATO:ssa
    Natossa

    If an acronym is pronounced as a word (like 'Nato'), it is treated as a normal noun and does not require a colon.

Learn This First

To understand how to use a colon before an ending, you first need to be familiar with the Finnish case system and how endings are generally attached to words. You also need to know basic numerals and abbreviations, as these are the specific instances where the colon is used to bridge the gap between the symbol and the grammatical ending. Finally, knowledge of vowel harmony is essential to choose the correct form of the ending after the colon.
