Formation
Borrowing
Borrowed from
Middle French corsaire

Pronunciation

  • IPA: /kɔːɹsɛəɹ/[1]

Etymology

It is borrowed from Middle French corsaire (“pirate”),[2][3][4][5][6] from Old Provençal corsari,[2][4][5][6] from Italian corsaro,[2][3][4][5][6] from Medieval Latin cursarius (“pirate, runner”),[2][3][4][5][6] from Latin cursus (“course, a running”),[2][3][4][5] from currere “to run”.[3][4] The sense of Medieval Latin cursus moved from “course” to “expedition” to a raid for plunder.[4][2][3] It is related to course.[2][5][6]

Earliest recorded meaning

A privateer of the Mediterranean, especially of the Barbary Coast (1549).[7][3][5]

Semantic evolution

The OED, quoted by Etymonline, notes that in English the word has often been treated as identical with pirate, although the Barbary corsairs were authorized by their own governments.[4][7] The word was applied to the ship itself from 1632.[7][4]
