Etymology: "Microphage" is a compound built from two Greek-derived elements. The first, "micro-", comes from the Greek "mikros", meaning "small," and is the common prefix in English for things of tiny scale. The second, "-phage", comes from the Greek "phagein", meaning "to eat," and appears in words for organisms or cells that consume something, such as "bacteriophage" or "macrophage." Put together, the term describes a small cell that eats. Biologists formed it on the pattern of "macrophage," the larger engulfing cell, which is why the pair is so closely related. The word therefore carries no older history of its own; it is a modern technical coinage assembled from classical building blocks to name a cell that surrounds and digests invaders and debris.

Synonyms: microbial predator, microscopic eater
