    • n ladder A frame of wood, metal, or rope, usually portable, and consisting essentially of two side-pieces connected at suitable distances by cross-pieces, generally in the form of rounds or rungs, forming steps by which, when the frame is properly set, a person may ascend a height. A ladder differs from a stair in that it has treads, but no risers. There are many forms of ladders, adapted to different uses, as the step-ladder, standing-ladder, companion-ladder, collapsing-ladder, scaliny ladder, etc. A firemen's scaling-ladder is now used consisting of one pole only with steps on each side and a large barbed hook at the top. In use, the hook is caught in a window-sill, the fireman climbs to the window by the pole, and then raises it to the next window, and so on.
    • n ladder Figuratively, any means of ascending; a means of rising to eminence.
    • n ladder In logic, a figure illustrating the theory of the old logic concerning the relations of genera, differences, and species
    • n ladder Nautical See Jacob's-ladder, 1.
    • n ladder A series of buckets for dredging and filling which are carried up and down an incline; a bucket-conveyer.
    • n ladder In railroads, a track which connects by switches the ends of a series of parallel tracks and is used in sorting cars in a drill-yard. See drill-yard.

Upon a ladder which, upreared,
Aided their ministry below.
