poimujen

Poimujen is the genitive plural form of the Finnish noun poimu, which translates roughly as fold, crease, or pleat. In Finnish, poimujen is used to refer to folds or creases belonging to something, or to describe the pattern of folds in a given context. The term is versatile and appears across several fields where folding or pleating is relevant.

Etymology and range of meaning: Poimu has a broad sense related to any surface or material that is folded. Because poimujen marks possession or association, the form is common when discussing specific sets of folds, such as the folds in fabric, rock layers, or anatomical structures. The core idea is a folded, pleated, or crumpled configuration.

In textiles: In fabric and garment terminology, poimujen describes pleats or gathers created by folding material. The arrangement and depth of poimut affect drape, texture, and fit. Descriptions often refer to poimutettu kangas (pleated fabric) or a design featuring poimut.

In geology and earth science: Poimut refers to a fold in rock strata produced by compressive forces. Geologists discuss structures such as anticlines and synclines as poimut of the Earth's crust, with poimujen used when referring to the folds of a particular rock sequence.

In biology and anatomy: Poimu is used for natural folds in tissues, such as the folds on membranes or organ surfaces. In neuroscience, brain gyri are described as poimut, i.e., the folded brain surface.
