Clandestine means done in secret on purpose, and kept out of sight — a meeting, a love affair, an operation, a sale. It is more formal than secret, and it often hints that somebody would be angry, or the law would care, if they knew.

Clandestine Clandestine means意思是 done in secret on purpose故意做得偷偷摸摸, and而且 kept out of sight藏得讓人看不到 a meeting像一場會面, a love affair一段戀情, an operation一次行動, a sale一筆交易。It它 is more formal than secret比secret更正式, and而且 it它 often hints常常暗示 that somebody would be angry要是被人知道有人會生氣, or或 the law would care法律也會在意, if they knew要是被發現的話。

A clandestine meeting sounds planned and hidden, not merely unspoken. You would not usually call a child's surprise party clandestine; you would call a hidden political group, a secret deal, or wartime work that.

A clandestine meeting一場clandestine的會面 sounds planned and hidden聽起來是有計畫、刻意隱藏的, not merely unspoken而不只是沒說出口而已。You你 would not usually call通常不會把 a child's surprise party一個小孩的驚喜派對 clandestine叫做clandestine; you你 would call倒是會這樣稱呼 a hidden political group一個隱密的政治團體, a secret deal一筆秘密交易, or或 wartime work戰時的工作 that那樣。

News, novels, and careful writing use it more than casual chat. Covert and undercover sit nearby, but clandestine is about the hidden doing, not only about spies.

News, novels, and careful writing新聞、小說，還有嚴謹的寫作 use it更常用這個字 more than casual chat比日常閒聊常用。Covert and undercover Covert和undercover這兩個字 sit nearby意思相近, but可是 clandestine clandestine is about重點在於 the hidden doing隱密的行動本身, not only about spies而不只是跟間諜有關。
