peittävyteen

Peittävyteen is the illative form of the Finnish noun peittävyys. Peittävyys refers to the property of being able to cover or obscure something, commonly understood as opacity or concealing power. In practical contexts, peittävyys is used to describe how well a layer hides what lies beneath, for example in paints, coatings, and camouflage, where higher peittävyys means stronger coverage.

As a linguistic form, peittävyteen appears whenever the illative case is required, indicating movement toward or into the concept of coverage or opacity. It is a standard part of Finnish grammar and is not a separate concept in itself, but a grammatical expression of the same underlying idea expressed by peittävyys. For instance, phrases like peittävyteen liittyvät ilmiöt discuss phenomena related to opacity or covering power.

In application, peittävyys is especially relevant in materials science, painting, and printing. In paints and coatings, it denotes how effectively a pigment can conceal the substrate, often described alongside terms such as katteet, väritaso, and peittävyysominaisuudet. The concept is also used in design and textiles where concealment or visual coverage matters. Related terms include peittävyys (opacity), peittämiskyky (covering ability), and peittämisvaikutus (concealing effect).
