In ancient Greek, questions were marked by a semicolon (Ερωτηματικό) rather than a question mark. This practice faded over time, and no special punctuation indicated questions in antiquity. The modern question mark emerged in the Middle Ages when scribes used “qo” (from Latin quaestio). To avoid confusion, they stacked the letters, turning the Q into a curl and the O into a dot, creating the question mark (“?”). In Spanish, the question mark was placed only at the end until 1754, when the Ortografía de la Real Academia introduced the inverted opening question mark (¿), as in: ¿Qué edad tienes? (How old are you?).
