energioihin

Energioihin is the illative plural form of the Finnish noun energia, meaning energy. It marks movement toward or into multiple energies or energy forms. The form is created by adding the illative plural suffix -ihin to the stem energia, and it appears in texts discussing several energy types or energy flows.

In standard Finnish, energioihin is used primarily in technical or academic contexts when referring to multiple energies, such as different energy forms (for example kemiallinen energia, kineettinen energia, potentiellinen energia) or in discussions of energy transfer between systems. Like other illative forms, energioihin expresses direction or movement toward what follows the verb.

The related plain form energia denotes energy in general, while energiat is the common plural nominative form. The illative plural energioihin is therefore a regular morphological variant rather than a separate concept, illustrating how Finnish encodes direction toward plural nouns.
