What is entasis nedir?

Entasis is a term used in architecture to describe the subtle curvature or swelling of a structure, especially columns, to overcome the appearance of tapering that would otherwise be present in a straight-sided structure. This technique has been used since ancient times to create the illusion of perfect straightness in columns and other architectural elements and to achieve a more pleasing visual effect. Entasis is a Greek word meaning "stretching" or "tension," and it is still used today in modern architecture and design to achieve a similar effect. The term is also sometimes used metaphorically to describe the gradual increase or expansion of something, such as the growth of a business or the evolution of an idea.
