Etymology
the term is a modern compound, formed in the 20th century from the greek-derived combining form 'bio-' and the english word 'warfare'. 'bio-' originates from the greek 'bios', meaning 'life', which is traced to the proto-indo-european root gʷeyh₃-, meaning 'to live'. 'warfare' is a native english compound from old north french 'werre' (war) and old english 'faru' (a journey, expedition). the literal combination, "life-warfare," logically evolved into the specific modern abstract meaning of using living organisms or their toxins as instruments of war, reflecting a technological and sinister application of biological science.
