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 easygoing and peaceful, preferring stability and routine over chaos. They tend to be good listeners and are often empathetic, making them supportive friends and colleagues. In modern psychology, the phlegmatic temperament is associated with traits such as patience, loyalty, and a strong sense of responsibility. While they may be perceived as passive or indecisive, phlegmatic individuals can be very effective in teamwork and conflict resolution, often acting as mediators in challenging situations.
