invested with or possessing full power.
The adjective plenipotent,“invested with or possessing full power,” comes from Late Latin plēnipotent– (stem of plēnipotēns), which is composed of plēni-, the combining form of plēnus “full” and potent-, the combining form of potēns, the present participle of posse “to be able, have power.” Plenipotent is not as common in English as its close relative, the adjective and noun plenipotentiary (as a noun, plenipotentiary usually refers to a diplomat with full power to conduct business or negotiations.) Plenipotent entered English in 1639; plenipotentiary in 1646.

a word or phrase that appears only once in a manuscript, document, or particular area of literature.
The phrase hapax legomenon, “a word or phrase appearing only once in literature,” comes from Greek hápax legomenon, composed of the adverb hápax “once, one time” and the neuter singular present passive participle legómenon “(being) said,” from the verb légein “to say.” (Hapax is also used by itself in English as a noun; the plural of hapax legomenon is hapax legomena.) One famous hapax—as far as these things go—is the adjective epioúsion in the phrase árton… epioúsion in the clause “(Give us this day our) daily bread,” in the Lord’s Prayer in the gospels of St. Matthew and St. Luke. The Greek noun ártos means “wheat bread, bread (in general)” and presents no problem. Epioúsion may mean “(enough) for today, today’s, next day’s, necessary, sufficient.” Epioúsion is variously translated in Latin: one of them, quotīdiānum “daily,” is an inadequate, even wrong translation of epioúsion, but it was used in Tyndale’s translation of the Bible (1534) and the King James Bible (1611), and it is used today in most modern English translations. Hapax legomenon entered English in the late 17th century.
