sanguine

Sanguine describes a person who maintains a positive, optimistic, and hopeful outlook, even in the face of difficult or uncertain circumstances. The word originates from the Latin "sanguis" (blood); in medieval medicine, a person with an abundance of blood was thought to be naturally cheerful and confident. It is a sophisticated term often used in journalism or formal writing to describe someone's temperament or their outlook on a specific event. While it implies optimism, it is distinct from "naive" because it suggests a level of composed confidence rather than a simple lack of awareness of potential problems.
