What does arcuated mean?
Arcuated is a formal adjective describing structures or forms that are built with, or shaped like, an arch. Its most important use lies in architectural terminology, where it distinguishes arch-based construction from trabeated systems, which rely instead on straight horizontal beams and lintels. The word derives from the Latin arcuatus, past participle of arcuare, 'to bend like a bow', itself rooted in arcus, 'bow' or 'arc' — the same root that gives us arch, arcade, and arcuate. Because arches carry loads by redirecting weight outward and downward along their curve, arcuated building made possible the great aqueducts, bridges, vaults, and cathedrals of Roman and Gothic architecture. In modern usage the term appears almost exclusively in scholarly writing, guidebooks, and technical criticism, giving it a learned, precise connotation. A related but distinct word, arcuate, describes any simple arc-like curvature, whereas arcuated implies actual arch construction or form.

"The cathedral's arcuated vaulting allowed the builders to span far wider spaces than post-and-lintel construction ever could."
"The Roman aqueduct's arcuated tiers of arches carried water across the valley for miles."
"In his treatise on Gothic design, he argued that arcuated structure freed masons from the weight limits of flat stone ceilings."
Before the arch, architecture was all straight lines and heavy lintels — arcuated building is what let the Romans span the world.
