demonstraatioksi

Demonstraatioksi is the translative form of the Finnish noun demonstraatio, meaning a demonstration in the sense of a display or illustration, as well as a mathematical or scientific demonstration (proof). The translative case -ksi marks a change of state or designation, so demonstraatioksi roughly translates as into a demonstration or as a demonstration.

Usage and meaning. The form is used when something is to serve as or be presented as a demonstration. It is common in instructional, demonstrative, or event-planning contexts. Examples of usage include phrases such as “Materiaali voidaan käyttää demonstraatioksi oppilaille” (the material can be used as a demonstration for students) and “Esitys järjestettiin demonstraatioksi tilaisuudessa” (the presentation was organized as a demonstration at the event). The sense is close to “for demonstration purposes” or “as a demonstration.”

Context and scope. In science and mathematics, demonstraatio commonly means a proof or a logical argument. The translative demonstraatioksi can appear when describing the role or function of a demonstration, for instance turning a procedure or result into something shown or presented to an audience. However, in technical mathematical writing the noun demonstraatio is more typical, and demonstraatioksi is used more for practical or communicative framing than for formal proofs.

Etymology and related terms. The word is derived from demonstraatio, itself from Latin demonstratio, through Finnish. Related forms include demonstraatio (nominative) and, in broader language use, phrases that describe demonstrations, displays, or proofs.
