2. Refers to a group of shapes with four equal sides and oblique angles as described in ancient mathematics ; designates little diamond or lozenge objects from the classical world ; indicates multiple geometric pieces or tablets shaped like rhombuses that were historically significant
3. Describes more than one parallelogram with equal sides and slanted angles from historical texts ; points to several rhombus-shaped implements or markers used by Greeks and Romans ; signifies a collection of diamond-shaped items important in scholarly or artifact discussions

Etymology: The term "rhomboi" is actually the plural form of "rhombo," a word that draws its origins from ancient Greek geometry. The singular "rhombo" stems from the Greek "rhombos," which referred to a spinning top or a shape that spins, and from there it came to describe a specific geometric figure—a diamond-shaped parallelogram with oblique angles. This shape, characterized by equal sides but angles that are not right angles, was studied extensively by Greek mathematicians. As the concept of geometry traveled through the centuries, the Greek "rhombos" passed into Latin as "rhombus," retaining its geometric meaning. English adopted "rhombus" around the late 16th century, primarily in mathematical contexts. The plural "rhomboi" follows the Greek pluralization pattern, where "-os" endings are replaced by "-oi," rather than the more common English or Latin plural forms. This usage is fairly specialized and typically appears in academic or historical discussions of geometry or classical languages. The shape itself has had practical applications beyond pure mathematics, appearing in art, architecture, and design, where its symmetrical yet dynamic form offers visual interest. The persistence of a Greek-derived plural form alongside more Anglicized versions underscores the influence of classical education and scholarship on certain fields where precision and historical continuity are valued. Thus, "rhomboi" connects modern users with a mathematical tradition that dates back over two millennia, preserving a direct linguistic link to the ancient Greek origins of geometric thought.
