Ribbed is an adjective that describes something that is marked or formed with ribs, which are raised, elongated, or rounded ridges or lines. The term "ribbed" is commonly used to refer to a particular type of surface or texture characterized by the presence of these ribs.
In a literal sense, it can be seen in architectural or structural elements like columns, beams, or vaults, where ribs are used to provide additional support or decorative features. These ribs enhance the strength of the structure and give it a distinctive appearance. Additionally, in the field of engineering, ribbed structures are used to improve the load-bearing capacity of materials, such as in ribbed steel plates or ribbed concrete structures.
In a more abstract sense, "ribbed" can refer to surfaces or textures that are deliberately designed or created to have these ridges or lines. For example, ribbed fabrics have raised lines or ridges running along their length, giving them a distinctive appearance and texture. Ribbed glass features parallel lines or ridges that add both aesthetic and functional benefits, such as improving grip or diffusing light.
Overall, "ribbed" describes anything that incorporates rib-like features, either for structural strength, enhanced appearance, or as a design choice to create unique textures.
Furnished with ribs; in bot., a leaf having strongly-marked nerves or veins.

The word "ribbed" comes from the Middle English word "ribben", which is derived from the Old English word "ribb", meaning "rib". The Old English word is further derived from the Proto-Germanic word "ribjon", which shares the same meaning. The term "ribbed" originally referred to the bones or ridges found on the surface of an object, resembling the shape of ribs. Over time, the word has also come to describe various patterns or textures that resemble or imitate these ridges, such as the ribbed surface of certain fabrics or rubber.
