täydennykseen

Täydennykseen is the illative singular form of the Finnish noun täydennys, which means supplement, addition or completion. In Finnish grammar, the illative case marks motion toward or into something, or a figurative direction toward a state or object. Therefore täydennykseen conveys “into the supplement” or “toward the supplement.” The term is most commonly found in formal or technical language, such as documentation, updates, or texts dealing with additions to a dataset, procedure, or written work.

Morphology and related forms: The base word täydennys is related to the verb täydennää or täydennätä (to complete, to supplement). Its genitive form is täydennyksen, and its illative form is täydennykseen. Other grammatical cases follow the standard Finnish noun declension pattern (for example, partitive would be täydennystä). The form täydennykseen is specifically used when the meaning involves moving toward or referring to a supplement, an addendum, or a supplementary part.

Usage: Täydennykseen occurs primarily in formal contexts such as reports, guidelines, legal or administrative text, and technical documentation when speaking about an added component, an appendix, or a supplementary section. It can be used metaphorically to indicate direction toward a new or additional material within a broader body of work.
