Origin of antibiotic

  • From French antibiotique, coined in 1889 by P. Vuillemin from anti- and biotique, from Ancient Greek βιωτικός (biōtikós, “concerning or relating to life”) (from βίος (bíos, “life”), from Proto-Indo-European *gʷeih₃w- (“to live”)), perhaps influenced by ἀντίβιος (antibios, “opposed”).
