sanguine… bilious… lymphatic… — terminological remnants from the “humoral” theories of human temperament. In these theories, there are four humors (bile, phlegm, blood, and atrabile) that correspond to the four elements (earth, water, fire, and air). The person of sanguinous temperament has an overabundance of blood, a.k.a. sanguine, associated with heat, moisture, and optimism, intuition and pride. Too much bilious humor and one has a dry, hot, choleric temperament, no-nonsense but prone to irritation. The lymphatic or phlegmatic temperament, moist and cold, is emotional and sympathetic.
