occuryoudaoicibaDictYouDict[occur 词源字典]
occur: [16] Etymologically, occur means ‘run towards’. It was borrowed from Latin occurrere, a compound verb formed from the prefix ob- ‘towards’ and currere ‘run’ (source of English course, current, etc). This had the sense ‘run to meet’, hence simply ‘meet’, which survived into English: ‘The whole multitude might freely move … with very little occurring or interfering’, Richard Bentley, Boyle Lectures 1692. But ‘meeting’ also passed into ‘presenting itself’, ‘appearing’, and hence ‘happening’ – from which the main present-day meaning of English occur comes.

bent (n.2)youdaoicibaDictYouDict
"stiff grass," Old English beonet, from West Germanic *binut- "rush, marsh grass" (cognates: Old Saxon binet, Old High German binuz, German Binse "rush, reed"), which is of unknown origin. An obsolete word, but surviving in place names (such as Bentley, from Old English Beonet-leah; Bentham).
The verdure of the plain lies buried deep
Beneath the dazzling deluge; and the bents,
And coarser grass, upspearing o'er the rest,
Of late unsightly and unseen, now shine
Conspicuous, and, in bright apparel clad
And fledg'd with icy feathers, nod superb.

[Cowper, "The Winter-Morning Walk," from "The Task"]

gerrymander (v.)youdaoicibaDictYouDict
1812, "arrange political divisions in disregard of natural boundaries so as to give one party an advantage in elections," also from 1812 as a noun, American English, from name of Elbridge Gerry + (sala)mander. Gerry, governor of Massachusetts, was lampooned when his party redistricted the state in a blatant bid to preserve an Antifederalist majority. One sprawling Essex County district resembled a salamander, and a newspaper editor dubbed it the Gerrymander. Related: Gerrymandered; gerrymandering.
[T]he division of this county into districts has given an opportunity for a Caracatura stamped at Boston and freely circulated here called the Gerrymander. The towns as they lie are disposed as parts of a monster whose feet and claws are Salem and Marblehead. It is one of those political tricks which have success as far as they go. [William Bentley, diary, April 2, 1812]
