Kolmitasoiseen

Kolmitasoiseen is a Finnish illative singular form of the adjective kolmitasoinen, meaning three-tiered or three-layered. The term describes something that is divided into or organized by three levels or layers. The base form kolmitasoinen is built from kolmi- (three) and tasoinen (having the character of, levelled). The illative suffix -iseen expresses movement into or direction toward a three-tiered object, as in kolmitasoiseen rakenteeseen (into a three-tiered structure).

In Finnish technical and descriptive writing, kolmitasoiseen is commonly used to specify systems, architectures, or models with three levels. It is part of a broader pattern in which compound adjectives describe structural properties and the illative case indicates spatial or conceptual direction toward that property. The bare nominative form kolmitasoinen, the genitive kolmitasoisen, and plural forms such as kolmitasoisia are used for different grammatical roles, while kolmitasoiseen serves when the sentence calls for “into a three-tiered …” or similar illative expressions.

Examples of usage include phrases such as kolmitasoiseen arkkitehtuuriin perustuva malli (a model based on a three-tier architecture) and kolmitasoiseen rakenteeseen sopiva ratkaisu (a solution suitable for a three-tier structure). These constructions are common in discussions of software architecture, data models, and organizational frameworks that are conceptually or physically divided into three levels.
