Etymology: "Ungrouped" is about as plain as English etymology gets: the prefix "un-" attached to "grouped," meaning not put into a group. The prefix goes back a long way. It descends from the Proto-Indo-European negative "*ne," which passed through Proto-Germanic and Old English as "un-" and has been used to reverse or negate words ever since. "Grouped" follows the same ordinary path, built from the noun "group" with the past-participle ending "-ed." Because both parts are native English building blocks, the word needs no borrowing from another language. It simply combines a long-standing negative prefix with an existing verb form, which is why it can be formed freely whenever a speaker wants to say that things have not yet been arranged into sets.
