What does geometrical mean?
Geometrical is a formal adjective meaning relating to geometry, the branch of mathematics concerned with shape, size, proportions, and spatial relationships. It can also describe something made up of regular geometric forms or patterns, such as a design of interlocking lines, circles, or polygons. In mathematical contexts, “geometrical reasoning” refers to reasoning based on spatial and proportional principles. In art, architecture, and design, the word often suggests deliberate order, symmetry, and mathematical structure. Although it is closely related to the much more common adjective geometric, geometrical tends to sound somewhat more formal and traditional, and it may emphasize a connection with geometry as a discipline rather than merely a geometric shape. The word is useful when describing both abstract mathematical ideas and visual forms governed by regular proportions. Its origin also reveals a striking connection between geometry and measurement.
adjectiveOf or relating to geometry. Characterized by regular geometric forms, proportions, or relationships.
- Relating to geometry or to the mathematical study of shape, size, and spatial relationships.
- Characterized by regular geometric forms, proportions, or patterns.
"The building's façade is decorated with striking geometrical patterns."
"The students used geometrical reasoning to determine the dimensions of the room."
"The textile design features interlocking geometrical shapes in deep blue and gold."
Geometrical literally points to measuring the earth: it comes from Greek roots for “earth” and “measure.”

Where does geometrical come from?
Geometrical comes through Latin geometricus, an adjective meaning “of or relating to geometry,” from Greek geometrikos, meaning “of or relating to measurement or geometry.” The Greek noun geometria was formed from ge, “earth,” and metron, “measure,” reflecting geometry's ancient concern with measuring land. The English adjective developed from these forms during the early modern period and is related to words such as geometry, geometric, and geometer.

How geometrical is actually used
Geometrical is formal and relatively uncommon compared with geometric. It is especially associated with mathematics, architecture, art, design, and descriptive writing; it does not by itself imply that something is perfectly accurate or precise.
Easily confused with geometrical
Both words can relate to geometry, but geometric is the more common modern adjective, while geometrical is often more formal and may emphasize the study of geometry or the formal principles of geometric form.
