Etymology: The word "responder" is a straightforward formation: "respond" plus the agent suffix "-er", which marks someone who performs the action. The suffix has a long ancestry. It descends from Proto-Italic forms that passed into Latin as "-arius", a suffix for people associated with a trade or role, and from there into Old French as "-ier". English took the same ending through two routes at once, as the native Old English "-ere" and the Old French "-ier" that became Middle English "-er", so "-er" arrived in English with deep roots in both traditions. The suffix is far older than the verb it now attaches to, and it has been used to build countless agent nouns, from "baker" to "writer". "Respond" itself came into English from Latin "respondere", meaning to answer, so the noun is simply the person who does the answering.
