Etymology

The word "questionnaire" originates from French, where "-aire" is a noun-forming suffix (similar to "-ary" in English). The root "question" comes from Latin "quaestio," meaning "a seeking or inquiry." The term evolved in French to denote a formal set of questions, and English adopted it in the 19th century to describe survey tools. The suffix "-aire" preserves its French influence, emphasizing the structured nature of the inquiry.
