Etymology: "Uncombine" is a plain formation: the prefix "un-", meaning "reverse the action of," attached to "combine." "Combine" itself comes from Late Latin "combinare," meaning "to join two things together," built from "com-" ("together") and "bini" ("two by two"), so the word's core idea is pairing things up. The prefix does the work here. "Un-" is one of English's most productive reversing prefixes, and it attaches readily to verbs that describe joining or assembling, as in "untie," "unlock," and "unfasten." "Uncombine" therefore needs no special history of its own: it simply names the reversal of a combining process, whether that process is chemical, mechanical, or social.
