cantilever

[tapoensgen]

cantilever |ˈkantɪliːvə|

noun
a long projecting beam or girder fixed at only one end, used chiefly in bridge construction.
• a long bracket or beam projecting from a wall to support a balcony, cornice, or similar structure.

verb [ trans. ] [usu. as adj. ] ( cantilevered)
support by a cantilever or cantilevers : a cantilevered deck.
• [ intrans. ] project as or like a cantilever : a conveyor cantilevered out over the river.

Any thoughts on the origin? Lever ought to originate from Latin levare - lift. But canti? Could it originate from contra - against?

We have bridge construction here, so I see what is meant.
This would be a good one for the doctor. Thanks for
