Syvennykseen

Syvennykseen is a Finnish illative form of the noun syvennys, meaning a hollow, depression, or indentation in the ground, or a figurative deepening. The illative case marks movement into the feature or state, so syvennykseen translates roughly as "into a hollow" or "into a depression." The word derives from the verb syventyä (to deepen) and the noun suffix -nys.

In geology and geomorphology, syvennykset refer to natural depressions, troughs, or subsidence areas; syvennykseen is used when describing movement into such a feature—for example in navigational descriptions or field notes. In literature and everyday language, the form can be used metaphorically to describe entering a deeper emotional or situational state.

Related forms include syvennys (nominative), syvennyksen (genitive), syvennyksessä (inessive), and plural syvennykset. The illative syvennykseen coexists with other case forms in sentences to indicate direction or movement into a space.

Examples:

- Hän astui syvennykseen ja kuunteli hiljaisuutta.

- Kartalla alueella on useita syvennyksiä.
