Jargon is the special words and phrases a job or a group uses, the kind that are hard for outsiders to follow. Doctors, lawyers, gamers, computer people, even school clubs have it. You usually treat it as a mass: too much jargon, full of jargon, not one jargon in everyday talk.

Jargon行話 is the special words and phrases a job or a group uses是某個行業或群體使用的特殊詞彙和說法 the kind that are hard for outsiders to follow那種外人很難聽懂的話。Doctors, lawyers, gamers, computer people, even school clubs醫生、律師、玩家、電腦人，甚至學校社團 have it都有自己的行話。You usually treat it as a mass日常說話裡通常把它當不可數名詞用：too much jargon too much jargon，太多行話 full of jargon full of jargon，滿滿的行話 not one jargon而不會說 one jargon。

People often say it with a sigh or a frown: you are shutting others out, or showing off. That disapproval is part of how the word feels.

People often say it with a sigh or a frown人們講這個字時常常帶著嘆氣或皺眉 you are shutting others out意思是你把別人擋在外面 or showing off或是在賣弄。That disapproval is part of how the word feels這種不以為然的味道，本來就是這個字的一部分感覺。

Though actually the tidy moral (“jargon is bad”) is tidier than real life. Specialists also need exact words so they do not mix up two close things; the same sentence can be precise inside the group and fog to everyone else. When a teacher asks you to “avoid jargon”, they mean: say it in ordinary English unless the exact term is doing real work.

Though actually不過其實 the tidy moral, jargon is bad「行話不好」這個簡單的教訓 is tidier than real life比真實情況整齊多了。Specialists also need exact words專業人士也需要精確的詞彙 so they do not mix up two close things才不會把兩個很接近的東西搞混 the same sentence can be precise inside the group同一句話在group內部可以很精確 and fog to everyone else對外人來說卻是一團霧。When a teacher asks you to avoid jargon當老師要你「避免用行話」時 they mean他們的意思是 say it in ordinary English用普通的英文說 unless the exact term is doing real work除非用那個精確的術語真的有作用。

As a verb, to jargon (to talk that way) exists but is rare; the noun is the one you will meet. Older English also used jargon for chatter that sounded like talk but did not carry clear meaning — bird noise, then human noise you cannot follow — and that old picture still sits under the modern complaint.

As a verb當動詞用 to jargon, to talk that way「to jargon」，那樣說話 exists but is rare是存在的，但很少見 the noun is the one you will meet你會遇到的通常是名詞用法。Older English以前的英文 also used jargon for chatter that sounded like talk but did not carry clear meaning也用 jargon指聽起來像說話、卻沒有清楚意思的嘰嘰喳喳 bird noise一開始是指鳥叫聲 then human noise you cannot follow後來變成你聽不懂的人的聲音 and that old picture still sits under the modern complaint這幅舊畫面至今仍藏在現代人的抱怨底下。
