To blab is to tell someone something that was supposed to stay secret. It is not careful reporting and not brave whistle-blowing.

To blabblab is就是 to tell someone把某件事告訴別人 something that was supposed to stay secret本來應該保密的事。It它 is not careful reporting不是謹慎的報導，and也 not brave whistle-blowing不是勇敢的吹哨爆料。

It is the leak that happens because a person cannot keep their mouth shut — they get excited, they want to seem important, or the words just slip out. “Don’t blab” is what you say to a friend who has just been trusted with news.

It它 is the leak that happens是那種洩漏 because a person cannot keep their mouth shut因為一個人管不住自己的嘴——they get excited他們太興奮了、they want to seem important想顯得自己很重要、or或 the words just slip out話就這樣溜出來了。"Don't blab""別blab出去" is what you say就是你會對 to a friend who has just been trusted with news一個剛被託付消息的朋友說的話。

The word is informal and a bit childish or teasing; adults still use it, but it sounds like playground talk, not a courtroom.

The word這個字 is informal and a bit childish or teasing不正式，還帶點孩子氣或開玩笑的味道；adults成年人 still use it還是會用它，but但 it sounds like playground talk聽起來像操場上的話，not而不是 a courtroom法庭上的話。

Though actually, blab can also mean “talk too much” in a looser way, not only about secrets: someone who blabs on may just be rattling out private details because they love talking. As a noun, a blab is that kind of person, though this is less common than the verb. It is never a polite or formal word for “inform.”

Though actually不過事實上，blabblab can also mean in a looser way也可以in a looser way比較鬆散地指 "talk too much"「講太多話」，not only about secrets不只是關於秘密：someone who blabs on一直blab個不停的人 may just be rattling out private details可能只是因為愛講話 because they love talking就滔滔不絕地把私事都講出來了。As a noun當名詞用時，a blab一個blab就是 is that kind of person那種人，though this is less common than the verb不過這個用法沒有動詞常見。It它 is never a polite or formal word絕對不是個禮貌或正式的字 for "inform"用來表示"inform"（通知）。
