2. 區(qū)分：pistol，piston: pistol "short firearm, small hand-held firearm", 有該詞的含義可知，它是一個指小詞，所以該詞末尾一定是一個指小的后綴：-ol. 而 piston 則不是指小詞，所以根據后綴區(qū)分就一目了然了。
3. 區(qū)分：pistol，piston: pistol 的尾字母l像一把槍，而 piston 的尾字母n則像是活塞外部的凹形槽。
4. 活塞：顧名思義就是“活動的塞子”，因此它是在一個凹形槽的內部按照一定頻率有規(guī)律地上下活動。
5. NBA: 底特律活塞隊: Detroit Pistons.

英文詞源
- 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.
