the.com/breadcrumb

means A trail of markers — whether literal crumbs or the clickable path showing your location in a website's structure — left behind so you or someone else can retrace the way back.

from From the literal crumbs of bread, the kind you'd drop to mark a path. The term leapt into tech and UX language in the late 20th century as a direct nod to the Hansel and Gretel folktale, where the children scatter crumbs through the forest to find their way home — though in the story, famously, birds eat the trail and the plan fails, a detail the digital metaphor quietly ignores.
