Etymology: "Irascibilis" is the Latin source of the English adjective "irascible," and it is built from "irasci," "to become angry," plus the suffix "-bilis," meaning "able to be" or "liable to." Its root is the verb "ira," anger, the same word that gave English "ire." So the Latin term literally means "able to be angered," which is a more precise description than the modern "prone to anger." English borrowed the word in the early 1500s, when "irascible" appeared in writing as a learned term drawn straight from Latin, a pattern common among scholars of that period who wanted precise vocabulary for temperament and humours. Unlike many Latin borrowings, it did not come through French, so its shape has stayed close to the original.
