venom Scientific  

/ vĕn′əm /

1. Any of various poisonous substances secreted by certain snakes, spiders, scorpions, and insects and transmitted to a victim by a bite or sting. Venoms are highly concentrated fluids that typically consist of dozens or hundreds of powerful enzymes, peptides, and smaller organic compounds. These compounds target and disable specific chemicals in the victim, damaging cellular and organ system function. Snake venoms, for example, contain substances that block platelet aggregation (causing bleeding) and that prevent the release of acetylcholine by nerve endings (causing muscle paralysis). Many substances contained in venoms are under investigation for use as pharmaceuticals.

Etymology

Origin of venom

First recorded in 1175–1225; variant of Middle English venim, from Anglo-French; Old French venim, venin, from (unattested) Vulgar Latin venīmen, for Latin venēnum “magical herb or potion, poison,” from (unattested) wenes-nom, equivalent to (unattested) wenes- desire ( see venerate, Venus) + (unattested) -nom noun suffix

Explanation

We’re pretty sure you wouldn’t drink a mysterious substance labeled “poisonous snake venom,” even if you didn’t know the meaning of venom. However, just to be clear, venom means "poison." Stay away from it. Venom is poisonous fluid produced by animals such as snakes, spiders, and certain people. Okay — we take that last one back, sort of. Scientifically speaking, people don’t produce venom, but they can certainly do so in a metaphorical sense. That’s why venom can also be used to mean “malice” or “hatred.” If you encounter someone who seems full of venom, remember that kindness can be a good antidote. (So can a really insulting remark.)
