Etymology: "Unsolder" is a plain English formation: the prefix "un-" attached to "solder," meaning to reverse the action of soldering. The reversing prefix "un-" comes from Old English "on-," which carried the same sense of undoing or reversal, and it has been used to form verbs like this since the Middle English period. Its ancestry runs back through Proto-Germanic "anda-" to a very old root that also gave Old English "and-," meaning "against" or "back." The base word "solder" is the more interesting half. It was borrowed into English from Old French "soudure," which came from Latin "solidare," meaning "to make solid" or "to consolidate." The idea was that two pieces joined by molten metal became one solid piece, which is why the word's core sense is about making things firm rather than about melting.
