Etymology: "Unchangeables" is simply the plural of "unchangeable," so its history is that of the adjective. The adjective was inherited from Middle English, where it appeared as "unchaungeable," built from the prefix "un-" meaning "not" and "changeable," which describes something capable of being altered. Used as a noun in the plural, it names a category of things that resist alteration, a sense that grows naturally from the adjective's basic idea of "not able to be changed."
