Eifunktionaalisia

Eifunktionaalisia is a Finnish phrase used to describe items that are not functional. The form is the plural partitive of ei-funktionaalinen, literally meaning "non-functional." While not a formal technical term in international fields, it is commonly found in Finnish-language texts to contrast functional and non-functional aspects of a system, product, or description. In practice, ei-funktionaalisia ominaisuuksia refers to non-functional features or characteristics that do not provide core functionality but influence usability, performance, reliability, or constraints of a design.

In usage, ei-funktionaalisia is often seen in contexts such as software engineering, product development, or system analysis, where authors distinguish between funktionaaliset vaatimukset (functional requirements) and ei-funktionaaliset (non-functional) aspects like usability, performance, security, or maintainability. Example sentences include: "Tässä tarkastelussa on erotettu funktionaaliset ja ei-funktionaaliset vaatimukset," and "Projektin menestystä arvioidaan sekä funktionaalisilla että ei-funktionaalisilla kriteereillä." The term thus functions primarily as a grammatical descriptor rather than as a formal concept with a universal definition across disciplines.

Etymology: the construction uses the negation prefix ei- with the adjective funktionaalinen, inflected as ei-funktionaalisia in the plural partitive. The phrase is mainly found in technical writing and analysis in Finnish and may appear alongside more standardized terms such as ei-funktionaaliset vaatimukset or ei-funktionaaliset ominaisuudet.
