Trapézový

Trapézový is a Czech adjective meaning “trapezoidal” or “having the form of a trapezoid.” The root word trapéz refers to a quadrilateral with at least one pair of parallel sides, and the suffix -ový turns it into an adjective. In geometry, a trapézový figure is characterized by having exactly one pair of sides that are parallel, while the other two sides are not. The term is used in the description of shapes in plane geometry, as well as in three‑dimensional contexts where one face of a polyhedron has a trapezoidal outline.

In everyday usage the term appears in fields such as architecture, engineering, and art. For example, a trapézový window frame is a frame whose top and bottom sides are parallel but whose lateral sides converge. In mechanical design, a trapézový shaft or joint may be used to accommodate specific load distribution or to fit into a shadow‑mirror assembly. The adjective is also employed in describing musical instruments, where the body of a trapézový flute has a trapezoidal cross‑section, influencing its acoustical properties.

Etymologically, the word derives from French trapèze, which in turn comes from the Italian trapezio, ultimately borrowed from Ancient Greek τραπέζιον (trapézion) meaning “table.” The adjective follows Czech adjective formation rules, adding -ový to the noun base. In written Czech, trapézový is capitalized only when it begins a sentence or appears in a title.
