Etymology

The word "questioner" derives from the Old French question (from Latin quaestio, meaning "a seeking or inquiry"), combined with the English agentive suffix -er. The Latin root quaerere (to seek, ask) evolved into question in Middle English, retaining its core meaning of inquiry. The suffix -er (from Old English -ere) systematically denotes a person performing an action, making "questioner" logically mean "one who asks questions." This construction reflects a straightforward Germanic-Latin hybrid pattern common in English.
