fist => piston, pistil, pestle.
2. 区分：pistol，piston: pistol "short firearm, small hand-held firearm", 有该词的含义可知，它是一个指小词，所以该词末尾一定是一个指小的后缀：-ol. 而 piston 则不是指小词，所以根据后缀区分就一目了然了。
3. 区分：pistol，piston: pistol 的尾字母l像一把枪，而 piston 的尾字母n则像是活塞外部的凹形槽。
4. 活塞：顾名思义就是“活动的塞子”，因此它是在一个凹形槽的内部按照一定频率有规律地上下活动。
5. NBA: 底特律活塞队: Detroit Pistons.

英语词源
- piston

piston: [18] The Latin verb pinsere meant ‘beat, pound’. Its past participial stem pist- formed the basis for the noun pistillum ‘grinding stick, pestle’ (from which English gets pistil ‘female flower part’ [18], an allusion to its shape). This passed into Italian as pestello, from which English gets pestle [14]. From the Italian stem pest- was formed pestone ‘rammer’, whose variant pistone gave French piston – whence English piston.
=> pestle, pistil - piston (n.)
- 1704, from French piston, from Middle French piston "large pestle," from Old Italian pistone "a piston," variant of pestone "a pestle," from pestare "to pound," from Late Latin pistare, frequentative of Latin pinsere (past participle pistus) "to pound" (see pestle). As a verb from 1930.
