Unnumbered source etymology

Original entry ↗
noun

A virus that is parasitic on bacteria.

Selected source glosses provide context, not a complete modern definition inventory

Clipping of bacteriophage from bacterio- (“bacteria”) + -phage (“eater”); latter suffix from Ancient Greek -φάγος (-phágos, “eater”), from φαγ- (phag-), aorist stem of ἐσθίω (esthíō) or ἔδω (édō, “to eat, to consume”). Stem φαγ- (phag-) may also derive from Proto-Indo-European *bʰeh₂g- (“to divide, distribute”) thus ultimately doublet of bhakti (via Sanskrit भक्ति (bhakti, “portion, division”) from root भज् (bhaj, “to divide, to apportion”)).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
