Where does the word “Cantilever” come from and What does Cantilever mean in architecture?

In college speech cantilever becomes, “Can’t I leave her?”

Though most certainly this interpretation has no bearing whatsoever on this type of “flying-lever bridge,” no satisfactory source of the canti- element has been determined.

As a term in architecture, the name appeared in the seventeenth century, pertaining to a masonry bracket of much greater length than depth.

Two such brackets united at the tips became a cantilever bridge early in the nineteenth century.
