corsair（n.）
"政府认可的海盗"，1540年代，来自法语 corsaire（15世纪），源自普罗旺斯语 cursar，意大利语 corsaro，源自中世纪拉丁语 cursarius "海盗"，源自拉丁语 cursus "路线，奔跑"，源自 currere "奔跑"（源自 PIE 词根 *kers- "奔跑"）。中世纪拉丁语动词的意义从"路线"演变为"旅程"，再演变为"掠夺性远征"。从1630年代开始，意为"私掠海盗船"。
The name in the languages of the Mediterranean for a privateer; chiefly applied to the cruisers of Barbary, to whose attacks the ships and coasts of the Christian countries were incessantly exposed. In English often treated as identical with pirate, though the Saracen and Turkish corsairs were authorized and recognized by their own government as part of its settled policy towards Christianity. [OED]
