What is camber? How to use in English

The word "camber" has a rich history. It originated in the 14th century from the Old French word "cambrer," meaning "to bend" or "to curve." This Old French word is derived from the Latin "camurus," meaning "crooked" or "bent." In the context of architecture and engineering, "camber" refers to the upward or downward curvature of a surface, such as a road, roof, or beam. This curvature serves to improve drainage, reduce stress, and enhance structural integrity. During the 14th to 16th centuries, the term "camber" gained popularity in medieval Europe, particularly in the construction of buildings, roads, and bridges. Today, the word "camber" is extensively used in various fields, including civil engineering, aviation, and sports, to describe the curvature of surfaces that serves a specific purpose.
