bottomless

This term evokes a sense of vertigo or overwhelming scale, shifting from a literal physical void to a psychological or material abundance. When describing a pit or ocean, it suggests a terrifying or awe-inspiring lack of a boundary, creating an image of eternal descent.

In commercial or personal contexts, the word transforms into a positive attribute of generosity or greed. It describes a resource that never runs dry, such as a bottomless brunch or an insatiable curiosity, where the focus is on the impossibility of depletion rather than physical depth.
