Etymology
The compound adjective "end-of-life" is a modern English formation built entirely from native Germanic elements. The core concept is a straightforward, literal combination of the noun "end," the preposition "of," and the noun "life," creating a phrasal unit that functions as a single modifier. Its application has evolved from a general description of life's conclusion to specific technical and medical contexts. In business and technology, it logically denotes the terminal phase of a product's commercial existence, while in healthcare, it refers to the period preceding biological death, demonstrating how a transparent literal construction can develop specialized, abstract meanings.
