The present participle of cantilate; the process of constructing or building something with cantilevers.
From the verb 'cantilate,' likely derived from Italian 'cantilena' or from 'cantilever' itself, which emerged as a technical term in architecture and engineering during the 17th-18th centuries.
Cantilating is what engineers call the tricky process of extending a structure beyond its support point—they have to calculate exactly how much weight can push outward before it becomes unsafe! The Tokyo Skytree's antenna cantilates so far out it needs special stress calculations.
