Etymology: "Validators" is the plural of "validator," a noun for a tool or mechanism that checks data against set criteria or standards. The word is built from "validate" plus the suffix "-or," which marks something that performs an action. "Validate" comes from Latin "validus," meaning strong or effective, so the core idea of the root is making something sound, legitimate, or capable of standing up to scrutiny. The suffix is the more interesting part of the chain. The English "-or" ending passed into Middle English through Old French, which had inherited it from Latin "-tor" and "-ātor," forms that marked the agent doing a deed. A validator is therefore, at its heart, a thing that does the validating, a checker built to do one job repeatedly and without fuss.
