frastagliati

Frastagliati is an Italian adjective meaning jagged, rough, or notched, describing outlines or surfaces that have irregular, tooth-shaped projections rather than smooth edges. The feminine form is frastagliata; the plural masculine frastagliati and feminine frastagliate are used to modify plural nouns. The term is common in geography, geology, biology, and design.

In geography and geology, frastagliato describes coastlines, rock faces, and terrain features formed by erosion or weathering, which create a serrated or crenulated profile. The phrase costa frastagliata (jagged coast) and roccia frastagliata (jagged rock) are typical. In biology and botany, frastagliato margins refer to leaves or bracts with uneven, tooth-like indentations, and in architecture and design, surfaces may be described as frastagliati to convey a rugged or dynamic appearance.

Frastagliature or frastagliamento are related nouns that denote the process or result of jagging. The term is widely used in Italian-language descriptions of natural scenery and man-made forms, and can be used metaphorically to describe irregular or complex patterns in data or structures.
