The word "Splandrel" is a geometric term used in architecture to refer to the space between an arch and a rectangular part of a wall. The spelling of the word can be confusing to those who are not familiar with the word, as it contains a silent "d" and an unfamiliar vowel sound. The appropriate IPA phonetic transcription for Splandrel is /ˈsplændrəl/. The word seems complicated to spell, but knowing the phonetics of the word makes it easier to understand and spell.
A spandrel refers to the triangular space that is formed between two adjacent arches or between an arch and a rectangular framework or column. Often overlooked in architecture, the term spandrel has various applications. In the context of architecture, it represents the area above a column, pier, or wall, which is enclosed by the outer curve of an arch. The term can also be used to describe the space between the top of a window or door and the arch or lintel that supports it.
In a broader sense, a spandrel can be any triangular or roughly triangular shaped space that is created by two intersecting lines or surfaces, forming the boundaries of a void. This definition allows for the term to be employed in fields other than architecture, such as mathematics and biology.
In mathematics, a spandrel can represent a curvilinear shape that is formed from the curved line connecting two intersecting straight lines. This concept is often utilized in geometry and trigonometry.
In biology, the term spandrel refers to a byproduct of an evolutionary process. It describes a trait or characteristic that is the result of natural selection acting on other features, rather than being directly selected for by evolutionary forces. A spandrel in this context can be thought of as an anatomical or behavioral feature that is not adaptive in itself, but exists as a result of other adaptive changes in an organism.
