kerrostuneena

Kerrostuneena is a Finnish term used to describe something that is composed of or arranged in layers. It comes from the verb kerrostua, meaning to layer or stratify, with the suffix -na that signals a state or manner. In both scientific and everyday Finnish, kerrostuneena denotes a layered or laminated texture or structure, as opposed to homogeneous or unlayered forms.

The word is commonly used in geology and materials science to describe stratified or laminated materials, such as sedimentary rocks, laminated minerals, or laminated composites. In everyday language it can describe any object or arrangement that presents multiple layers, for example a cake with several fillings or clothing worn in distinct layers. In Finnish descriptions, kerrostuneena conveys the sense that layers are visible or structurally important to the subject being described.

Etymologically, kerrostuneena illustrates how Finnish forms convey state or manner by combining a base verb with the -na suffix. Related terms include kerrostua (to layer, to become layered), kerrostuminen (stratification), and kerros (layer); laminaatio and other compounds are used in technical contexts. The concept of layering is central to geology, materials science, and everyday materials, where kerrostuneena functions as a concise descriptor of layered structure.
