Uh-uh is a way of saying no without using a word — two low grunts with a break between them, both on a flat or falling tune. Written down it looks confusing, but you already know the sound.

Uh-uh uh-uh is a way of saying no without using a word是一種不用任何字就能表示「不」的方式 —— two low grunts with a break between them是兩個中間有停頓的低沉哼聲， both on a flat or falling tune語調都是平的或下降的。 Written down寫下來的時候 it它 looks confusing看起來很奇怪， but不過 you你 already know the sound早就知道那個聲音是什麼樣子。

It means no, don't, or I disagree, and it works as a full answer on its own: 'Did you finish it?' 'Uh-uh.' It can also be a warning to stop someone reaching for something, said sharply.

It它 means no, don't, or I disagree意思是「不」、「不要」，或「我不同意」， and而且 it它 works as a full answer on its own自己一個字就可以當完整的回答： 'Did you finish it?'「你做完了嗎？」 'Uh-uh.'「Uh-uh。」 It它 can also be也可以是 a warning to stop someone reaching for something一個阻止別人伸手拿東西的警告， said sharply很尖銳地說出來。

It is very informal, so it belongs with friends and family; answering a teacher, a customer or an interviewer with uh-uh sounds careless or rude, and in those places you say no or a full sentence. Some people also feel it is a little childish, since it is the first 'no' many children use.

It它 is very informal非常口語， so所以 it它 belongs with friends and family適合用在朋友和家人之間； answering用uh-uh回答 a teacher, a customer or an interviewer老師、客戶或面試官 with uh-uh， sounds careless or rude聽起來會很隨便或沒禮貌， and而 in those places在這些場合， you你 say no or a full sentence應該說no或講一個完整的句子。 Some people有些人 also feel也覺得 it它 is a little childish有點幼稚， since因為 it它 is the first 'no' many children use是很多小孩最早學會說的「不」。

Because it is a sound rather than a word, it varies: some speakers close the lips and hum it instead, as 'mm-mm', which means exactly the same thing.

Because因為 it它 is a sound rather than a word是個聲音而不是一個字， it它 varies所以會有不同版本： some speakers有些人 close the lips and hum it instead會閉著嘴用哼的代替， as 'mm-mm'變成「mm-mm」， which而這個 means exactly the same thing意思完全一樣。
