Etymology: Albert Calmette, a French physician working in Lille and later at the Pasteur Institute in Paris, spent the 1890s developing serums against snake venom. His 1894 work on treating snakebites gave the world a new name for the remedy: "antivenin," built from the Latin prefix "anti-" ("against") and "venin," the French word for venom. The term arrived in English as a borrowing from French, so it carries the same clinical flavour it had when Calmette first used it. Antivenin sits in a small family of near-synonyms that came into English around the same time. "Antivenom" is an English formation on the same pattern, and "antivenene," which uses a Greek-derived ending, is a further variant. All three are doublets in the loose sense that they express one idea through different word-building routes. The plural "antivenins" is simply the ordinary plural of "antivenin," used when speaking of several different serums, batches, or species-specific treatments.
