hackyoudaoicibaDictYouDict[hack 词源字典]
hack: English has two distinct words hack. By far the older, ‘cut savagely or randomly’ [OE], goes back via Old English haccian to a prehistoric West Germanic *khak-, also reproduced in German hacken and Dutch hakken. It perhaps originated in imitation of the sound of chopping. Hack ‘worn-out horse’ [17] is short for hackney (as in hackney carriage), a word in use since the 14th century in connection with hired horses.

It is thought that this may be an adaptation of the name of Hackney, now an inner-London borough but once a village on the northeastern outskirts of the capital where horses were raised before being taken into the city for sale or hire. Most rented horses being past their best from long and probably ill usage, hackney came to mean ‘broken-down horse’ and hence in general ‘drudge’.

This quickly became respecified to ‘someone who writes for hire, and hence unimaginatively’, which influenced the development of hackneyed ‘trite’ [18]. The modern sense of hacker, ‘someone who gains unauthorized access to computer records’, comes from a slightly earlier ‘one who works like a hack – that is, very hard – at writing and experimenting with software’.

[hack etymology, hack origin, 英语词源]
capitulation (n.)youdaoicibaDictYouDict
1530s, "an agreement," from Middle French capitulation, noun of action from capituler "agree on specified terms," from Medieval Latin capitulare "to draw up in heads or chapters, arrange conditions," from capitulum "chapter," in classical Latin "heading," literally "a little head," diminutive of caput (genitive capitis) "head" (see capitulum). Meaning narrowed by mid-17c. to "make terms of surrender."
Catch-22 (n.)youdaoicibaDictYouDict
from the title of Joseph Heller's 1961 novel. In widespread use only after release of the movie based on the book in 1970. The "catch" is that a bomber pilot is insane if he flies combat missions without asking to be relieved from duty, and is thus eligible to be relieved from duty. But if he asks to be relieved from duty, that means he's sane and has to keep flying.
There was only one catch and that was Catch-22, which specified that a concern for one's safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. Yossarian was moved very deeply by the absolute simplicity of this clause of Catch-22 and let out a respectful whistle.

"That's some catch, that Catch-22," he observed.

"It's the best there is," Doc Daneeka agreed.
