superb (adj.) Look up superb at Dictionary.com
1540s, "noble, magnificent" (of buildings, etc.), from Latin superbus "grand, proud, splendid; haughty, vain, insolent," from super "above, over" (see super-). The second element perhaps is from PIE root *bhe- "to be." General sense of "very fine" developed by 1729. Related: Superbious (c.1500); superbly.
