What Are Ordinal Numbers?
Ordinal numbers are used to indicate order or position in a sequence. In English, these are words like “first,” “second,” and “third.” In Finnish, ordinal numbers serve the same function, but their forms and usage follow unique grammatical rules.
Basic Formation of Ordinal Numbers in Finnish
In Finnish, ordinal numbers are generally formed from their corresponding cardinal numbers (yksi – one, kaksi – two, kolme – three, etc.) by adding specific endings. The typical suffix for ordinal numbers is -s or -as/-äs, followed by further inflection as needed.
Key Patterns for Forming Ordinal Numbers
- First (1st): poikkeus (exception) – ensimmäinen
- Second (2nd): poikkeus – toinen
- Third (3rd): poikkeus – kolmas
- Fourth (4th): neljäs
- Fifth (5th): viides
- Sixth (6th): kuudes
- From seventh onward, ordinal numbers are generally formed by adding -s or -as/–äs to the cardinal number stem.
Special Cases: First, Second, and Third
The ordinal numbers for “first” (ensimmäinen), “second” (toinen), and “third” (kolmas) are irregular and must be memorized. These do not follow the regular suffix rules that apply to other numbers.
General Rule for Higher Ordinals
Starting from “fourth,” ordinal numbers are formed by taking the stem of the cardinal number and adding the appropriate suffix:
- 4th – neljäs (neljä + -s)
- 5th – viides (viisi + -des)
- 6th – kuudes (kuusi + -des)
- 7th – seitsemäs (seitsemän + -äs)
- 8th – kahdeksas (kahdeksan + -as)
- 9th – yhdeksäs (yhdeksän + -äs)
- 10th – kymmenes (kymmenen + -es)
For numbers above ten, use the ordinal form of the last word in the compound number:
- 11th – yhdestoista (literally, “the first of the second [ten]”)
- 12th – kahdestoista
- 20th – kahdeskymmenes (“the second of the tenth”)
- 21st – kahdeskymmenesensimmäinen (“the first of the twentieth”)
Declension and Agreement
Finnish ordinal numbers behave like adjectives, which means they must agree in case, number, and sometimes gender (where applicable) with the noun they modify. For example:
- Ensimmäinen päivä – The first day (nominative case)
- Ensimmäistä päivää – Of the first day (partitive case)
- Ensimmäisen päivän – Of the first day (genitive case)
This agreement applies to all ordinal numbers, so be sure to match the case ending of the ordinal with the noun it describes.
Using Ordinal Numbers in Dates and Addresses
Ordinal numbers are commonly used to express dates and in addresses:
- 15. päivä marraskuuta – The 15th of November (literally, “the 15th day of November”)
- Toinen kerros – The second floor
- Kolmas ovi vasemmalla – The third door on the left
In writing, ordinal numbers can be abbreviated with a period after the numeral: 1., 2., 3., etc., when used before nouns.
Common Mistakes and How to Avoid Them
- Confusing cardinal and ordinal forms: Remember that “yksi” is “one,” while “ensimmäinen” is “first.”
- Incorrect case agreement: Always ensure your ordinal number matches the case of the noun.
- Mixing up suffixes: Pay attention to the irregular forms and memorize them separately from regular patterns.
Practice Makes Perfect
Ordinal numbers are an essential part of everyday Finnish. Practice using them in context—talk about dates, order in a queue, or give directions using ordinal numbers.
