Etymology: "Intercepter" is an alternative spelling of "interceptor," and the story of its making is a plain one: it is a compound of "intercept" and the agent suffix "-or," meaning something that performs the action. "Intercept" comes from Latin "intercipere," literally "to take between," built from "inter" (between) and "capere" (to take), so the core idea is of seizing something on its way from one place to another. The suffix has a longer journey. It descends from a Proto-Italic form and reached English through Latin "-tor" and the Old French "-eor," which settled into Middle English as "-our" before shifting to the "-or" spelling used today. Because "-or" attaches so readily to verbs, English speakers have freely formed agent nouns from it, and "interceptor" is one of many words built this way, naming a thing or person that stops something in transit.
