Etymology: "Unadvised" is a plain formation: the prefix "un-", meaning "not", attached to "advised," the past participle of "advise." Its ancestor in Middle English was "unavised," built the same way from "avised," an older form of "advised." The source shows no other rival history, and none is needed here. Its sense has stayed close to its roots. "Advised" once carried the idea of having looked at something carefully, so to be "unadvised" was to have acted without that careful consideration. That is why the adjective still means doing something without thinking it through, rather than simply lacking counsel from others.
