這個拼法底下其實是2個不同的字，意思沒有關係， 只是長得一樣。下面分開列出來。跳到 剁刀 · 直升機
chopper
nOne way to hold this word is as a short, repeated downward stroke. Something is raised and brought down, again and again, and whatever is under it comes apart into pieces. English calls that action chop, and adding -er names the thing that performs it. So the picture is not a shape but a motion: a blade falling on a rib, a set of blades spinning in a jar, a jaw closing on a mouthful. Point that picture at different objects and you get a heavy kitchen knife, a little machine on the counter, and a row of teeth.
From the word’s history
Wiktionary gives this entry as chop + -er, i.e. 'something that chops', through Old English -ere and Middle English -ere.
Wiktionary 把這一條字源寫成 chop 加上 -er，也就是「會 chop 的那個東西」，-er 這個字尾一路從古英語 -ere、中古英語 -ere 傳下來。所以「剁」的畫面不是後人編的聯想，字源本身就是這樣組成的。

A second word, same spelling
chopper
n, vThis second centre is a sound, not a blade. A helicopter's rotor beats the air in fast, even strokes, and you hear that beat long before the aircraft comes into view: chop, chop, chop, over the ridge. English named the machine after what it sounds like, and then used the same word as a verb for the thing it does — carrying people and supplies in and out of places nothing else can reach.
From the word’s history
Wiktionary gives this as a separate etymology: the word comes from the onomatopoeic 'chop-chop' of the main rotor blades of the Bell 47 'OH-13 Sioux' helicopter, as heard by troops during the Korean War.
Wiktionary 把這一組列為另一條字源：它來自擬聲詞 chop-chop，也就是貝爾 47「OH-13 Sioux」直升機主旋翼的聲音，韓戰期間士兵在戰場上聽到而流傳開來。所以這個名字記的是耳朵聽到的東西，不是手上拿的刀。
