The term "phlegmatic" refers to one of the four temperaments in ancient Greek medicine, characterized by a calm, reliable, and thoughtful nature. People with a phlegmatic temperament are often seen as peaceful and easygoing, tending to avoid conflict and maintain a steady demeanor in various situations. They are typically good listeners and can be very supportive friends. In modern psychology, the phlegmatic personality is associated with traits such as patience, loyalty, and a preference for routine. While they may not be the most expressive individuals, their stability and dependability make them valuable in both personal and professional relationships.
