记忆方法
1、sharp 字面就是"能切的"（来自 PIE*sker「剪、切」，同 shear、share）：刀刃利、眼力尖、脑子快、话说得刻薄、疼得剧烈——五摊事都从"能切"来，不用一条条死记。
2、同根一起背：shear 剪、share(原本指切下来的一份)、score(在木头上刻痕记数)。反义配着记 dull / blunt(钝)。
3、sharp 还能当副词表整点：at 9 o'clock sharp。读音是长音 /ʃɑːp/，别读成"西普"；拼写是 -arp 不是 -ar。

英语词源
- sharp
-
sharp: [OE] Sharp, together with its close relatives German scharf, Dutch scherp, and Swedish and Danish skarp, goes back to a prehistoric Germanic *skarpaz. This was probably descended from an extension of the Indo-European base *sker- ‘cut’ (source of English score, share, shear, etc). Welsh has borrowed sharp as siarp.
=> shear - sharp (adj.)
- Old English scearp "having a cutting edge; pointed; intellectually acute, active, shrewd; keen (of senses); severe; biting, bitter (of tastes)," from Proto-Germanic *skarpaz, literally "cutting" (cognates: Old Saxon scarp, Old Norse skarpr, Old Frisian skerp, Dutch scherp, German scharf "sharp"), from PIE *(s)ker- (1) "to cut" (cognates: Lettish skarbs "sharp," Middle Irish cerb "cutting;" see shear (v.)).
The figurative meaning "acute or penetrating in intellect or perception" was in Old English; hence "keenly alive to one's own interests, quick to take advantage" (1690s). Of words or talk, "cutting, sarcastic," from early 13c. Meaning "distinct in contour" is from 1670s. The adverbial meaning "abruptly" is from 1836; that of "promptly" is first attested 1840. The musical meaning "half step above (a given tone)" is from 1570s. Meaning "stylish" is from 1944, hepster slang, from earlier general slang sense of "excellent" (1940). Phrase sharp as a tack first recorded 1912 (sharp as a needle has been around since Old English). Sharp-shinned attested from 1704 of persons, 1813 of hawks. - sharp (n.)
- "a cheat at games," 1797, short for sharper (1680s) in this sense. Meaning "expert, connoisseur" is attested from 1840, and likely is from sharp (adj.). Music sense is from 1570s. The noun was used 14c. as "a sharp weapon, edge of a sword."
