cantilever

First attested in the 1660s, probably from cant (“slope”) + lever, but the earliest form (c. 1610) was cantlapper. First element may also be Spanish can (“dog”), an architect's term for an end of timber jutting out of a wall, on which beams rested.

     The service stairs were next to the main stairs, separated only by a wall, but what a difference there was between them: the narrow back stairs, dangerously unrailed, under the bleak gleam of a skylight, each step worn down to a steep hollow, turned tightly in a deep grey shaft; whereas the great main sweep, a miracle of cantilevers, dividing and joining again, was hung with the portraits of prince-bishops, and had ears of corn in its wrought-iron banisters that trembled to the tread.
