噴射機與搭機到處飛
飛機這一支是從核心畫面長出來的:引擎把高溫氣體從後面用力噴出去(就是那條 jet),機身因此被往前推。所以 jet 先是引擎噴出的那股氣,後來整架靠這種方式飛的飛機也叫 jet。
fast passenger aircraft · noun · B1
A fast airplane that is pushed forward by a jet engine.
噴射機
Picture water forced through a tiny hole: it does not spread or trickle, it shoots out in one thin, hard, fast line. That narrow high-speed stream — and the little hole that makes it — is the picture at the centre of the word. Everything about pushing something out fast through a small opening grows from here, including the aircraft that flies by throwing hot gas out behind it.
The stream sense comes from French jet 'a throw, a cast; a gush, spurt (of water)', from the verb jeter 'to throw'. The nozzle sense is recorded from 1825, 'jet propulsion' from 1855, 'jet engine' from 1943, and the aircraft sense from 1944 — so the plane is named after the throwing-out of gas, not the other way round.
「噴流」這一支來自法文 jet「投擲、噴出(水柱)」,動詞是 jeter「丟、擲」。字典記載 1825 年開始指噴嘴,1855 年出現 jet propulsion(噴射推進),1943 年 jet engine,1944 年才用來指飛機——所以是先有「往外噴」,飛機才因為靠噴氣推進而得名。

這一組跟「噴出」沒有任何關係,只是拼法碰巧一樣。學的時候可以直接把它當成另一個字記,不用硬去想它跟水柱有什麼關聯。
