ladder
UK: ˈlædə | US: ˈlædər
n. a structure consisting of two parallel sides connected by rungs, used for climbing up or down
n. a series of stages or levels in a hierarchy or process (e.g., "the corporate ladder")
The word "ladder" traces back to Old English hlǣder, derived from Proto-Germanic hlaidrijō, meaning "something to lean or climb." The root hlǣd- is linked to the action of leaning or inclining, reflecting the tool's function. Over time, the spelling simplified to "ladder," while retaining its core meaning of a climbing device. The metaphorical use for hierarchical progression emerged later, drawing on the visual analogy of ascending steps.
