Etymology: "Lacrimator" is formed in English from "lacrimate", meaning to shed tears, plus the agent suffix "-or", which denotes a thing or person that performs an action. A lacrimator is therefore literally something that makes you weep. The base verb comes from Latin "lacrimare", from "lacrima", "tear", which gives the English word its root. The suffix has a longer ancestry than the word itself. The "-or" ending descends from Latin "-or" and "-tor", which marked agents, and it reached English through Old French and Middle English, where it was a common way to form nouns for doers of actions. English kept the pattern productive, so speakers could attach it to a verb like "lacrimate" whenever a name for a tear-causing agent was needed. The word is a technical coinage rather than an ancient term. Its use for chemical irritants in crowd control and self-defence reflects the modern context in which such substances were developed, and the Latin building blocks simply supplied a precise, scientific-sounding label.
