Fun Fact

“Sanguine” comes from the Latin “sanguineus,” meaning “of blood,” and was originally used in medieval medicine as one of the four humors (bodily fluids) that were thought to determine a person’s physical and mental qualities. According to this ancient theory, having a predominance of blood made one warm, social, and optimistic – hence “sanguine.” The medieval physicians believed that people with a sanguine temperament had rosy cheeks and a robust constitution due to the healthy balance of blood in their system. This connection between blood and temperament was so established that artists would often portray sanguine characters with distinctly red or pink complexions. Interestingly, the word maintains a dual meaning in medical contexts, where it can still refer to things relating to blood, while in everyday usage it describes optimistic personality traits. This makes it one of the few words that preserved both its literal and metaphorical meanings from medieval medicine into modern times.
