Etymology
The compound adjective 'rusted-out' is a modern formation built from core Germanic elements. The first element, 'rust', originates from Old English and describes the corrosive oxidation of iron. The '-ed' suffix attaches to the noun, turning it into a participial adjective meaning 'affected by rust'. The final particle 'out' intensifies the meaning, conveying a sense of being completely worn through, exhausted, or broken down due to that rusting process. Thus, the term's literal logic is transparent: an object that has rusted to the point of being completely used up or broken.
