- superior (adj.)
- late 14c., "higher in position," from Old French superior "higher, upper" (Modern French superieur), from Latin superiorem (nominative superior) "higher," comparative of superus "situated above, upper," from super "above, over" (see super-).
Meaning "higher in rank or dignity" is attested from late 15c.; sense of "of a higher nature or character" is attested from 1530s. Original sense was preserved more strongly in French (cf. les étages supérieur "the upper stories"), and in Lake Superior, a loan-translation of French Lac Supérieur, literally "upper lake" (at 600 feet above sea-level it has the highest surface elevation of the five Great Lakes and is the furthest north).
- superior (n.)
- early 15c., from Latin superior (see superior (adj.)), used in Medieval Latin with a noun sense of "one higher, a superior."
