elämänaineisiin

Elämänaineisiin is a Finnish neologism used mainly in speculative, philosophical, or fictional contexts to refer to substances associated with life. The term fuses elämä (life) and aine (substance) with the illative plural suffix -isiin, forming a coined compound that is not standard in everyday Finnish. Because it is not established in dictionaries or formal terminology, its precise meaning can vary by author or discourse.

In practice, elämänaineisiin can denote the chemical constituents and environmental factors that enable life. This may include basic building blocks such as water and carbon-based molecules, energy sources, essential elements, and other nutrients that sustain metabolism and growth. The concept is often discussed in broad terms to contrast life-supporting milieus with inert or non-living matter, rather than to identify a fixed list of substances.

The term also appears in science fiction and speculative philosophy to frame discussions about what kinds of substances are necessary for life under different conditions or on other planets. In these uses, it serves as a label for the pantry of chemicals and resources that hypothetical organisms would require, rather than as a formal scientific category.

Note: Because elämänaineisiin is a neo-formation with variable usage, readers should rely on the context in which it appears to determine its intended scope.
