记忆方法
1、看到 scr- 就想"拧、刮、转"：screw（螺丝、拧）、scratch（刮、抓）、scream（尖叫）开头都这股劲。螺丝就是一圈圈拧进去的，画面直接长在拼写上。
2、动词用法一串：screw on 拧上、screw off 拧下、screw up 搞砸（口语）；screwdriver（螺丝刀）= screw + driver（驱动工具的东西）。
3、易错三点：拼写是 e 在前、w 收尾（不是 scrue）；读音 /skruː/，ew 发长音"乌"，和 crow（乌鸦）不同音；have a screw loose（口语：脑子少根弦、不太靠得住）。吝啬鬼、囚犯这两个俚语义只在小说口语里碰得到，先不背。

screw: [15] Screw comes ultimately from a Latin word meaning ‘female pig’ – scrōfa (source also of English scrofula [14], a disease to which pigs were once thought to be particularly prone). By the medieval period scrōfa was being used for a ‘screw’, mainly no doubt in allusion to the pig’s curly, corkscrew-like tail, but also perhaps partly prompted by the resemblance to Latin scrobis ‘ditch, trench’, hence ‘cunt’, which was used in Vulgar Latin for the ‘groove in a screw-head’ (the use of the verb screw for ‘copulate’, first recorded in the early 18th century, is purely coincidental).
English got the word from Old French escroue, which came either directly from Latin scrōfa or via prehistoric West Germanic *scrūva (source of German schraube ‘screw’).
=> scrofula - screw (n.)
- "cylinder of wood or metal with a spiral ridge round it; hole in which a screw turns," c. 1400, from Middle French escroue "nut, cylindrical socket, screwhole," of uncertain etymology; not found in other Romanic languages. Perhaps via Gallo-Roman *scroba or West Germanic *scruva from Vulgar Latin scrobis "screw-head groove," in classical Latin "ditch, trench," also "vagina" (Diez, though OED finds this "phonologically impossible").
Kluge, Watkins and others trace it to Latin scrofa "breeding sow," perhaps based on the shape of a pig's penis (compare Portuguese porca, Spanish perca "a female screw," from Latin porca "sow"). Latin scrofa is literally "digger, rooter," from PIE root *(s)ker- (1) "to cut" (see shear (v.)). A group of apparently cognate Germanic words (Middle Low German, Middle Dutch schruve, Dutch schroef, German Schraube, Swedish skrufva "screw") are said to be French loan-words.
Sense of "means of pressure or coercion" is from 1640s, probably in reference to instruments of torture (such as thumbscrews). Meaning "prison guard, warden" is 1812 in underworld slang, originally in reference to the key they carried (screw as slang for "key" attested from 1795). Slang meaning "an act of copulation" is recorded from 1929 (meaning "a prostitute" is attested from 1725). To have a screw loose "have a dangerous (usually mental) weakness" is recorded from 1810. - screw (v.)
- "to twist (something) like a screw," 1590s, from screw (n.). From 1610s as "to attach with a screw." Slang meaning "to copulate" dates from at least 1725, originally usually of the action of the male, on the notion of driving a screw into something. Meaning "defraud, cheat" is from 1900. First recorded 1949 in exclamations as a euphemism. Related: Screwed; screwing. To screw up "blunder" is recorded from 1942. Screwed up originally was figurative for "tuned to a high or precise pitch" (1907), an image from the pegs of stringed instruments. Meaning "confused, muddled" attested from 1943. Expression to have (one's) head screwed on the right (or wrong) way is from 1821.
