noun someone who habitually doubts accepted beliefs
originBorrowed from Middle French sceptique (but with a pronunciation closer to that of the Greek etymon), or possibly directly from Late Latin scepticus (originally attested only in the plural Scepticī (“the sect of Skeptics”)), from Ancient Greek σκεπτικός (skeptikós, “thoughtful, inquiring”), from σκέπτομαι (sképtomai, “to consider”), compare to σκοπέω (skopéō, “to view, examine”).
