What does it mean if a person is described as phlegmatic?

A person described as phlegmatic is characterized by a calm and composed demeanor, often displaying little emotion or excitement. This temperament is associated with a steady and even-keeled personality, suggesting that such an individual does not easily fluctuate between highs and lows in mood. The term originates from the ancient concept of the four bodily humors, where phlegm was thought to govern a person's disposition and was linked to a tranquil and unflappable nature.

In this context, "unemotional or calm" aptly captures the essence of phlegmatic individuals as they tend to maintain their composure in various situations, contrasting sharply with more emotionally charged dispositions. Therefore, this descriptor fits seamlessly with the meaning of phlegmatic. The other choices imply more dynamic emotional states or a lack of concern, which do not align with the characteristics typically associated with a phlegmatic personality.
