soprano n.

word-forming element meaning "above, over, beyond," from Latin super (adverb and preposition) "above, over, on the top (of), beyond, besides, in addition to," from *(s)uper-, variant form of PIE root *uper "over." In English words from Old French, it appears as sur-. The primary sense seems to have shifted over time from usually meaning "beyond" to usually meaning "very much," which can be contradictory. E.g. supersexual, which is attested from 1895 as "transcending sexuality," from 1968 as "very sexual."

early 14c., of persons, "great, superior, supreme;" mid-14c., "having supreme power;" from Old French soverain "highest, supreme, chief," from Vulgar Latin *superanus "chief, principal" (source also of Spanish soberano, Italian soprano), from Latin super "over" (from PIE root *uper "over"). Of remedies or medicines, "potent in a high degree," from late 14c.
