In classical Greek, the word telos (τέλος) translates literally to "end," "purpose," "goal," or "completion." Originating prominently in Aristotelian philosophy, it denotes the ultimate objective, inherent purpose, or final destination toward which a natural process, system, or human action is directed. In philosophical discussions, understanding the telos of an entity helps explain its underlying design, function, and reason for existence within a structured framework.
