Emily Dickinson Lexicon

SUV'E-RAN, a. [Fr. souverain; Sp. and Port. soberano; It. sovrano; from L. supernus, superus, super. The barbarous Norman word souvereign, seems to be formed of L. super and regnum; a strange blunder. The early authors, Chaucer and others, wrote this word soverain, souvereyn, which were more correct than the modern spelling.]

1. Supreme in power; possessing supreme dominion; as, a suveran prince. The Creator is the suveran ruler of the universe.
2. Supreme; chief; superior to all others.
3. Supremely efficacious; superior to all others; as, a suveran remedy.
4. Supreme; pertaining to the first magistrate of a nation; as, suveran authority.
