Etymology

The word "erode" originates from Latin "erodere," combining "e-" (away) and "rodere" (to gnaw). It originally described the literal gnawing away of material (e.g., soil by water) and later extended metaphorically to abstract weakening (e.g., trust eroding). The imagery of gradual destruction remains central to its meaning.
