inbuktning

Inbuktning is a Swedish term that refers to an inward bending or concave feature in a surface, object, or structure. The concept covers any recess or inward curvature, whether natural or man-made. It can describe a dent in a metal panel, a groove or pocket in a component, or an inward curve along the edge of a material. In geography, inbuktningar are indentations along coastlines, such as coves or bays that extend inward from the main shoreline. In geology and engineering, the term may describe inward deformation, pockets formed by erosion, or manufactured recesses in parts and assemblies. In biology and botany, concave recesses or grooves on surfaces can also be described as inbuktningar, depending on context.

Measuring an inbuktning typically involves its depth (how far inward the surface recesses), its width (the horizontal extent), and sometimes the radius of curvature of the concave area. The severity or prominence of an inbuktning is often discussed in relation to these geometric parameters, as well as the surrounding surface geometry.

The term is contrasted with utbuktning, which denotes outward bulging or protrusion. Related terms include indentation, concavity, groove, and recess. Etymologically, inbuktning combines in- (toward, inward) with buktning (a noun form from bukt/bukta, related to bending or bulging).
