haze (v.)youdaoicibaDictYouDict
"subject (someone) to cruel horseplay," 1850, American English student slang, from earlier nautical sense of "harass with work, punish by keeping at unpleasant and unnecessary hard labor" (1840), perhaps from hawze "terrify, frighten, confound" (1670s), from Middle French haser "irritate, annoy" (mid-15c.), which is of unknown origin. Related: Hazed; hazing.
All hands were called to "come up and see it rain," and kept on deck hour after hour in a drenching rain, standing round the deck so far apart as to prevent our talking with one another, with our tarpaulins and oil-cloth jackets on, picking old rope to pieces or laying up gaskets and robands. This was often done, too, when we were lying in port with two anchors down, and no necessity for more than one man on deck as a look-out. This is what is called "hazing" a crew, and "working their old iron up." [Dana, "Two Years before the Mast," 1842]
purchase (n.)youdaoicibaDictYouDict
c. 1300, purchas, "acquisition, gain;" also, "something acquired or received, a possession; property, goods;" especially "booty, spoil; goods gained by pillage or robbery" (to make purchase was "to seize by robbery"). Also "mercenary soldier, one who fights for booty." From Anglo-French purchace, Old French porchaz "acquisition, gain, profit; seizing, plunder; search pursuit, effort," from Anglo-French purchaser, Old French porchacier (see purchase (v.)).

From early 14c. as "endeavor, effort, exertion; instigation, contrivance;" late 14c. as "act of acquiring, procurement." Meaning "that which is bought" is from 1580s. The sense of "hold or position for advantageously applying power" (1711) is extended from the nautical verb meaning "to haul or draw (especially by mechanical power)," often used in reference to hauling up anchors, attested from 1560s. Wif of purchase (early 14c.) was a term for "concubine."
