Paralyzer

Part of speech: noun

Definitions

1. A substance or method that instills a condition of immobility or diminished responsiveness in a living creature
2. An agent or device that induces inability to move or react in a person or animal
3. A tool, chemical, or means that leads to paralysis or loss of voluntary movement

Etymology: The most useful fact here is how plainly this one is built. It is formed from "paralyze" with the agent suffix "-er", which English has used since Old English to name a person or thing that does something, as in "baker" or "teacher". So a paralyzer is literally whatever paralyzes. The verb "paralyze" comes from the Greek "paralyein", meaning to loosen at the side, from "para" (beside, aside) and "lyein" (to loosen). The Greek sense was loosened or disabled limbs, and the word passed into Latin as "paralysis" before reaching English. Over time the meaning widened from a bodily loss of movement to any sudden inability to act, as when a shock leaves someone frozen. The "-er" ending itself came into English through Old English "-ere" and Middle English "-ere" and "-er", tracing back to Latin "-arius" through Old French "-ier". This is why the same ending appears in so many occupation words, and why "paralyzer" reads as an ordinary English formation rather than a borrowing.
