Sanguine comes from the Latin word sanguis, meaning “blood.” In ancient times, it was believed that a person’s temperament was influenced by the balance of four bodily fluids, or “humors,” with sanguine being associated with an optimistic and cheerful disposition. Today, the term is used to describe a positive and hopeful outlook, particularly in challenging circumstances. Cultivating a sanguine attitude can foster resilience, perseverance, and a belief in the potential for success.
