"Corbelled" is spelled with two "L"s at the end, despite being pronounced with only one. The IPA phonetic transcription of this word is /kɔːˈbɛld/. The double "L" is due to its origin from the Old French word "corbel", which means "bracket". The spelling of "corbel" was retained when it was adapted into English, and the suffix "-ed" was added to create "corbelled". Despite its unconventional spelling, "corbelled" is a common term in construction and architecture, referring to the technique of creating an overhang by gradually stepping the supporting structure.
Corbelled (verb): The term "corbelled" is commonly used in the fields of architecture and construction to describe a specific technique or method of building that involves gradually projecting or overlapping successive rows of stones or bricks to create an arch or a structure that gradually narrows towards the top.
The corbelled technique is often employed in the construction of arches, vaults, and even fortification walls. With each successive layer, the stones or bricks are laid so that they extend slightly beyond the lower layer, creating an inclined surface that supports the weight and gradually closes in on itself. This method allows for the formation of an arch without the need for a central supporting element, such as a keystone.
Corbelling can also refer to the use of bracket-like projections, called corbels, that support beams or other architectural features. These corbels are usually made of stone, wood, or other materials and are strategically placed to add strength, stability, and aesthetic appeal to the structure.
The corbelled technique has been employed by various cultures throughout history, including ancient Egyptians, Greeks, and Romans. In modern architecture, this technique is often used to create visual interest or to pay homage to historical architectural styles.
Overall, "corbelled" refers to the act of progressively overlapping stones or bricks to form an arch or to provide support in the construction of architectural structures.
The word "corbel" comes from the Middle French word "courbe" meaning "curve" or "arch". It is derived from the Latin verb "corvus" meaning "crow" or "raven". The term "corbelled" is the past participle form of "corbel", and it refers to a technique in architecture where each successive course of stones or bricks is set slightly beyond the previous one, creating a corbelled arch or structure. Thus, its etymology is based on the shape and construction method used in architectural design.
