Root for living, yielding Latin vivere, Greek bios/zoe, English quick (alive), vital.
Discussion
The Proto-Indo-European root *gʷeyh₃- carried the fundamental meaning "to live, to be alive" and stands as one of the most productive roots in the entire reconstructed lexicon. Its derivatives permeate virtually every branch of the Indo-European family, reflecting the central importance of the concept of life itself. The root displays a characteristic laryngeal *h₃, which coloured the preceding vowel and was lost in most daughter languages, though its effects remain visible in the lengthened vowel grades of certain derivatives.
In Latin, the root produced vivere "to live", yielding English vivid, vivacious, revive, survive, and vital. The Latin noun vita "life" gave rise to vitamin, a coinage of the early twentieth century. Greek saw the development of bios "life", the source of English biology, biography, biography, and antibiotic, alongside the form zoe "life" (from the zero-grade *gʷih₃-), which surfaces in words such as zoo and zoology. The shift from the labio-velar *gʷ to Greek b before certain vowels is a well-established sound correspondence.
In the Germanic branch, the root underwent Grimm's Law, by which the Proto-Indo-European voiced labio-velar *gʷ became *kw, eventually yielding Old English cwic "alive", the ancestor of modern English quick. The original sense of quick was not "fast" but "alive" — a meaning preserved in the phrase "the quick and the dead" and in quicksilver, literally "living silver". The semantic shift from "alive" to "fast" occurred gradually during the Middle English period, as liveliness became associated with rapidity.
Sanskrit contributed jivati "lives" and jiva "living", cognate forms that confirm the antiquity of this root. The related root *gʷeyh₃-tó- produced the past participle meaning "alive, living", which developed into Latin vita and its extensive English progeny. The breadth of this root's descendants — spanning biology, medicine, philosophy, and everyday speech — testifies to its deep place in the Proto-Indo-European conceptual world.
