kaksivuotisista

Kaksivuotisista is a Finnish inflected form of the adjective kaksivuotinen, meaning “two-year-old.” It is used to describe plural nouns in the elative case, typically referring to a group consisting of two-year-old individuals. In Finnish, adjectives agree with the noun in number and case, so kaksivuotisista appears before a plural noun in the elative.

Declension notes:

- Nominative plural: kaksivuotiset

- Genitive plural: kaksivuotisten

- Partitive plural: kaksivuotisia

- Elative plural: kaksivuotisista

These forms illustrate how the adjective changes to match different grammatical roles in a sentence, while the head noun carries the corresponding case ending.

Usage:

Kaksivuotisista is common in statistical, educational, and health writing when describing groups of children or animals by age. It can appear in phrases such as “kaksivuotisista lapsista koostuva otos” (a sample composed of two-year-old children) or “kaksivuotisista potilaista kertova tutkimus” (a study describing two-year-old patients).

Etymology:

The term combines numerals kaks (two) and vuosi (year) with the suffix -nen to form an adjective meaning “two-year-old.” The elative plural ending -ista/-istä marks a set of two-year-olds as the source or origin in a sentence, depending on context.
