Fundamentteihin

Fundamentteihin is a Finnish noun form that functions as the illative plural of fundamentti. Fundamentti means foundation, base, or underpinning, in both physical and abstract senses. The illative case marks direction toward or into something; thus fundamentteihin translates roughly as “to the foundations” or “into the foundations” when used with a plural subject or destination.

In terms of related forms, the base is fundamentti; the nominative plural is fundamentit; the illative singular is fundamenttiin; the illative plural is fundamentteihin; the genitive plural is fundamenttien. The form fundamentteihin is most common in technical, architectural, and construction contexts, where components, anchors, or measurements are described as directed toward or placed into the foundations.

In non-technical language, speakers typically prefer the words perusteet or perusta when referring to abstract foundations, though fundamentti can still appear in formal or specialized texts when the emphasis is on the structural basis of a system. As a directional illative plural, fundamentteihin signals both plurality and movement toward the foundational elements of a building or concept, and it is used where such a destination is relevant to the discussion.
