Etymology: "Unimplemented" is a plain construction: the prefix "un-" attached to "implemented," meaning "not yet built, put into effect, or carried out." The prefix goes back a long way. It descends from a Proto-Indo-European negative particle, reached Old English as "un-," and has been a productive English prefix ever since, so English speakers can attach it to almost any verb or participle, as here. The base word "implemented" comes from "implement," which is itself a verb built on "implement" in the sense of a tool or piece of equipment. Its participle form, "implemented," took on the sense of having been put into practice, so the negated form points to a plan or policy that exists on paper but has not yet been carried out.
