reunoiksi

Reunoiksi is a Finnish grammatical form derived from the noun reuna, which means edge, border, or boundary. In Finnish, the suffix -ksi marks the translative case, used to express change of state or role. When used in its plural translative form reunoiksi, it conveys the sense of “to the edges” or “as edges” and is typically applied to a plural subject.

In practice, reunoiksi appears in texts describing transformation, categorization, or labeling in diagrams, designs, or mathematical models. For example, a sentence might indicate that a shape or surface is being defined or changed to function as edges rather than its interior. The form is primarily a technical or formal construction rather than everyday language, and it is most common in disciplines such as geometry, computer modeling, and engineering documentation.

Usage notes:

- Reunoiksi is the plural translative form of reuna; the singular form is reunaksi.

- It denotes movement toward or a redefinition into edges, borders, or boundary features.

- Its appearance is typical in formal writing about shapes, surfaces, or spatial descriptions.

Related concepts in Finnish grammar include the translative suffix -ksi and other translative forms used to describe changes in state, roles, or functions. Reunoiksi therefore occupies a niche but clear place in technical Finnish, where precise description of spatial or structural transformation is required.
