kasulikkusel

Kasulikkusel is a term used in Estonian language and discourse to refer to the concept of usefulness. It denotes how valuable or practical a tool, action, method, or idea is in a given context. The base noun is kasulikkus (usefulness), and kasulikkusel is a grammatical form used to express “on usefulness” or “in terms of usefulness” in sentences.

Linguistically, kasulikkusel is formed from kasulik (useful) plus the noun-forming suffix -kus, yielding kasulikkus (usefulness). The form kasulikkusel is the adessive case form of kasulikkus, and it is used to frame statements about usefulness, for example in analysis, discussion, or evaluation. This morphological feature allows speakers to specify the perspective or basis of a statement, such as focusing on usefulness in policy, design, or research.

In usage, kasulikkusel often appears in philosophical, economic, or practical contexts where usefulness is a criterion for judgment. Common phrases include kasulikkusel põhinevad otsused (decisions based on usefulness) and kasulikkusel arvestamine (consideration of usefulness). While kasulikkus remains the general term for usefulness, kasulikkusel helps situate discourse around the practical implications and value of a given option or action.
