Pronunciation: [sˈɒlɪd skwˈe͡ə] (IPA) 
The spelling of the word "solid square" can be explained in IPA phonetic transcription as /ˈsɑːlɪd skweər/. The first syllable is pronounced with a long "o" sound, followed by a short "i" and a "d" sound. The second word begins with a "sk" sound, followed by a "w" sound and an "air" sound. "Solid square" refers to a geometric shape that has four equal sides and angles, and is not hollow or transparent.
A solid square is a geometric shape that possesses several defining characteristics. It is a quadrilateral, meaning it has four sides, each of which is equal in length. Additionally, all four angles within a solid square are right angles, measuring 90 degrees. This creates a shape with four congruent sides and four congruent angles, resulting in a highly symmetrical figure.
The term "solid" in this context refers to a square that is three-dimensional rather than flat or two-dimensional. It implies that the shape has thickness, occupying space in three dimensions. This differentiates it from a flat or planar square that exists solely on a two-dimensional plane.
Typically rendered as a cubic or rectangular solid with equal-length faces, the solid square offers a harmonious blend of uniformity and ordered structure. Due to its properties, a solid square is known for being highly stable and resistant to deformation, making it a prominent choice in constructions and various engineering applications.
Solid squares can be found in various contexts, such as architecture, design, puzzle-solving, and mathematics. They often serve as fundamental building blocks for more complex structures and geometric patterns. Moreover, solid squares possess aesthetic appeal due to their balanced symmetry, resulting in striking visual displays and a sense of orderliness.
A body of troops in the form of a square in which the ranks and files are equal.

The word "solid" comes from the Latin word "solidus", which means "firm, whole, or unbroken". The term "solid" in English emerged in the mid-14th century to describe something that is not hollow, empty, or fluid, but rather compact and dense.
The word "square" originated from the Latin word "quadrus", which means "square" or "four-sided". This Latin term was derived from the Proto-Indo-European root "*kwetwer-, k(w)etwor-", which also gave rise to words in other Indo-European languages denoting the number four or the concept of being square or quadrangular.
When these two words combine, "solid square" refers to a shape with four equal sides and four right angles that is also entirely filled or filled with a solid material throughout.
