Expressing Subsets with the Elative Case
In Finnish, when you want to specify a part of a larger group—like saying "one of us" or "two of the members"—you use a quantifier followed by the elative case (which carries the core meaning "out of").
[Quantifier] + [Group in Elative]
When the group consists of multiple individuals, you use the plural elative (typically ending in -ista/-istä). Personal pronouns also take their elative forms, such as meistä (of us) and teistä (of you).
| Which of you wants to be the chairperson of the committee? | Kuka teistä haluaa olla toimikunnan puheenjohtaja? |
| Two of the committee members will vote tomorrow. | Kaksi toimikunnan jäsenistä äänestää huomenna. |
Proportions and Other Quantifiers
Beyond numbers, this structure is used with proportion words and other quantifiers, such as osa (a part / some), moni (many), jokainen (each/every), and the negative pronoun kukaan (no one / none).
| Some of the members support the new chairperson. | Osa jäsenistä tukee uutta puheenjohtajaa. |
| Each of the colleagues gets a new area of responsibility. | Jokainen kollegoista saa uuden vastuualueen. |
| None of the decision-makers were at the meeting. | Kukaan päättäjistä ei ollut kokouksessa. |
Collective Nouns
If the larger group is a single collective entity, such as a committee or a board of directors, you use the singular elative (-sta/-stä) to extract a proportion.
| The majority of the board of directors agrees after the vote. | Enemmistö johtokunnasta on samaa mieltä äänestyksen jälkeen. |
