Etymology
The word 'phage' is a direct shortening of 'bacteriophage', a term coined in the early 20th century from the Greek elements 'bakterion' (small rod) and 'phagein' (to eat). The core morpheme 'phag-', meaning 'to eat' or 'to devour', is of Proto-Indo-European origin, related to concepts of consumption. In 'phage', this ancient root vividly describes the virus's action of consuming or destroying its bacterial host. The modern, standalone term retains this literal imagery, succinctly defining an entity that eats bacteria.
