Etymology: "Exolution" is a rare English noun meaning release from solution, and it comes directly from Latin "exolutio," meaning "a release." That Latin noun was built from "exolvere," "to loosen or undo," which combines the prefix "ex-" ("out") with "solvere" ("to loosen"). The same "solvere" root gave English "solve," "dissolve," and "solution," so the word belongs to a whole family of ideas about loosening and untying. The English term keeps the Latin sense of unfastening and applies it to chemistry, where a substance is released from a dissolved state. Because "solution" in English can mean both a liquid mixture and the act of solving a problem, the "exo-" prefix makes the chemical sense clearer: the material comes out of the solution rather than merging into it.
