Struktuurivad

Struktuurivad is an Estonian term used in technical discourse to describe properties, rules, or transformations that preserve the structural integrity of a system. The word is formed from struktuur and the participial suffix -ivad, and it functions as an adjective and, in plural form, to refer to these structure-preserving elements or operations.

In mathematics and computer science, struktuurivad mappings or operations preserve the relevant structure when relating different objects, such as homomorphisms, isomorphisms, or functors that carry operations and relations from one structure to another without altering core properties. In linguistics and cognitive science, the term may describe rules or processes that maintain underlying syntactic or semantic structure during transformations. In other disciplines, struktuurivad concepts similarly denote invariants or constraints that survive transformations.

Usage notes and scope: the term is most common in Estonian-language texts. In English, it is often translated as “structure-preserving.” The concept aligns with ideas of invariants and canonical forms in formal theories, and it is closely related to related notions such as morphisms, invariants, and structure-preserving mappings.
