The word skeptic traces back to ancient Greek philosophy, where the Skeptikoi were thinkers who advocated questioning all claims to absolute knowledge. The root skept- reflects their method of careful examination, while the suffix -ic generalizes it into a term for anyone adopting such an attitude. Over time, it broadened to describe doubters in everyday contexts, retaining its core link to scrutiny.
