Etymology: Autophagia is a compound built from two Greek-derived elements: "auto-", meaning "self," and "-phagia," from Greek "phagein," "to eat." Put together, the word literally means "self-eating," and the "-phagia" ending is the same one found in words like "polyphagia" (eating excessively) and "dysphagia" (difficulty swallowing). The biological sense, an organism consuming parts of its own body or cells, is what the compound was built to name. Its meaning is therefore plain and descriptive rather than the product of centuries of drift: the word states exactly what happens, with each element contributing its literal sense. The same "self-eating" idea underlies the cellular process of autophagy, a related term that describes cells breaking down their own components.
