Etymology: A questioner is simply someone who asks questions. The word is a plain English formation, built from "question" and the agent suffix "-er", which turns a verb into a noun for the person doing the action, as in "teacher" or "builder." No single coiner or memorable episode lies behind it. The base word comes to English through Old French "question" from Latin "quaestio," a noun from "quaerere," "to seek, ask, or inquire." That same Latin verb lies behind English "query," "inquire," "acquire," and "require," so a questioner shares its ancestry with a surprising family of everyday words.
