Etymology: The prefix "un-" here is the ordinary English negating prefix, inherited from Old English "un-", which goes back to a Proto-Germanic form of the same sense and ultimately to the Proto-Indo-European negative "*n̥-". So the word is not a classical coinage but a native English construction. It attaches to "characterized," the past participle of "characterize," which itself comes from the Greek "kharaktēr," meaning a mark or engraved stamp. Built from "un-" plus "characterized," the adjective simply means "not characterized," that is, lacking the distinguishing features that would let it be classified. The pattern is productive: English readily negates past participles this way, as with "unknown" or "unfinished," so the formation needed no special coinage.
