Etymology
The word "bile" entered English in the mid-16th century, borrowed directly from the French "bile," which itself descended from the Latin "bilis." This Latin term referred specifically to the digestive fluid secreted by the liver. The conceptual link between the physical substance and the emotion is ancient; in the classical theory of the four bodily humors, an excess of black bile (melancholy) or yellow bile (choler) was believed to cause irritable, angry, or melancholic temperaments. Thus, the modern abstract meaning denoting bitterness of temper evolved directly from this physiological and psychological doctrine, preserving the ancient logic that internal fluids govern disposition.
Analysis
The word is a simplex loanword from Latin. It cannot be meaningfully segmented into smaller morphemes within its current English spelling.
