Taittuma

Taittuma is a Finnish noun that denotes a crease, fold, or bend in a surface or object. It is most commonly used to describe lines formed when fabric, paper, or other flexible materials are folded or pressed, and it can also refer to scoring lines introduced to guide folding in manufacturing or crafts.

The term is built from the Finnish verb taittaa, meaning to bend or fold, combined with the nominalizing suffix -uma, which conveys the resulting feature or state. In everyday language, taittuma often appears in contexts such as clothing and textiles (creases and pleats), paper products (fold lines and creases), and packaging or bookbinding (folded sheets and scored lines).

In specialized contexts, taittuma can have more technical uses. In crafts and design, it describes visible crease lines that influence the drape or appearance of a material. In geology, the word may be encountered to refer to a fold in rock layers, reflecting its broader sense of a deformation feature produced by bending; however, technical literature typically uses more specific terminology for structural geology.

Overall, taittuma functions as a versatile descriptor of folded or creased forms across crafts, manufacturing, and, in some cases, natural geology. Its exact meaning is guided by context, with emphasis on the visible line or feature created by folding or bending a material.
