nesteytykseen

Nesteytykseen is the illative form of the Finnish noun nesteytys, which denotes hydration or the act of adding moisture to a substance. In Finnish grammar, the illative form expresses direction toward a state or outcome, so nesteytykseen can be understood as “into hydration” or “for hydration.” It is used when a statement refers to the aim, destination, or purpose of the hydration process.

The term appears in scientific, culinary, and industrial texts whenever moisture is introduced to reach a target moisture level, texture, stability, or reactivity. Nesteytykseen is a grammatical form rather than a separate concept; it links a verb or phrase to the intended outcome of hydration. For example, it may appear in phrases describing materials or processes intended to undergo hydration, or in procedural descriptions specifying hydration as a goal.

Etymology and form: nesteytys is formed from nest(e) (fluid) with the nominalizing suffix -tys, giving the base meaning hydration. The illative form nesteytykseen is created by adding the illative suffix -kseen to that base, signaling direction toward the state of hydration.
