What does envenom mean?
Envenom is a transitive verb meaning to inject or introduce venom into a living thing, most commonly through a bite or sting. Beyond its literal use in describing how snakes, spiders, and other venomous creatures subdue prey or defend themselves, envenom has long served as a powerful metaphor: words, rivalries, or resentments can be said to envenom a relationship when they fill it with bitterness and hostility. This figurative sense gives the word a distinctly literary flavour, appearing in Shakespeare and later writers to describe speech or sentiment that wounds like a poisoned blade. In modern medical contexts the related noun envenomation names the clinical condition resulting from such exposure. Though not an everyday word, envenom remains vivid and precise, useful whenever one wants to suggest poisoning that is deliberate, penetrating, and morally corrosive.

Etymology of envenom
Envenom comes from the Old French word 'envenimer', formed from 'en-' (a causative prefix) plus 'venim', which itself derives from the Latin 'venenum' meaning poison. English borrowed the verb in the late medieval period, and by the sixteenth century it was well established both literally and figuratively. It shares this Latin root with 'venom', 'venomous', and 'venenate', all of which trace back to the same classical source.
