Etymology
the word 'humoral' originates from the ancient latin concept of humor, which referred to a bodily fluid. this term itself stems from the proto-indo-european root wegʷ-, meaning 'wet' or 'moist', which evolved into the latin humere. in medieval and renaissance medicine, it was believed that four cardinal humors (blood, phlegm, yellow bile, black bile) governed human health and temperament. the suffix -al was attached to form an adjective, leading to the modern medical and immunological sense of something pertaining to or circulating in bodily fluids.
