What does cantilevering mean?
Cantilevering is the present participle of the verb 'to cantilever,' meaning to construct, extend, or support a structure by means of a cantilever — a rigid beam or slab anchored firmly at one end while projecting freely into space, unsupported from below. In architecture and structural engineering, cantilevering makes possible dramatic balconies, bridges, roofs, and floors that appear to float, because the load is carried back through the anchored end rather than through columns beneath the overhang. The word appears most often in technical descriptions of construction methods and in writing about notable buildings, such as houses whose upper stories jut boldly over cliffsides or water. Cantilevering carries connotations of modernist daring and engineering skill, since it defies the intuitive expectation that every projection must be propped up. Related forms include the noun 'cantilever' and the participle 'cantilevered.'
Present participle of 'cantilever': to build, extend, or support a structure using a projecting beam anchored at only one end.

Frank Lloyd Wright built Fallingwater by cantilevering its terraces over a waterfall in 1935 — and the beams sagged so much they needed emergency reinforcement decades later.

Etymology of cantilevering
The verb 'cantilever' derives from the noun 'cantilever,' first recorded in English in the mid-17th century as an architectural term for a projecting bracket. Its etymology is genuinely debated: one widely cited theory derives it from 'cant' (an angle or edge, ultimately related to Latin 'cantus') combined with 'lever' (from Old French 'levier,' from Latin 'levare,' to raise); another account traces it to a supposed dog-Latin phrase 'quanto liber' ('how much does it weigh'), reflecting the beam's load-bearing role. The verb form arose later, in the 19th century, when large-scale iron and steel construction made cantilever bridges and buildings common.
