Every spoken language has noises that mean nothing but do a job: they hold the floor while your brain catches up. English has "um," "uh," "like," "I mean." Chinese has 嗯 (èn), 那个 (nàge), 这个 (zhège), and 就是 (jiùshì). The one that ambushes learners is 那个 — you already know it as the demonstrative "that" (那个人 "that person"), but dropped into a pause it is the exact twin of English "uh…", with no referent at all. Miss that and you'll waste effort hunting for the "thing" a speaker never meant. This page teaches the fillers as pure disfluency, flags the famous 那个 pronunciation point, and keeps them apart from the interactive stance tags 你看 / 我觉得, which do carry a function.
The fillers at a glanceFillerReadingEnglish twin嗯èn / ń"um, uh" — the pure vocalized pause那个nàge / nèige"uhh…" — stalling while you find the word这个zhège"this… uh…" — same job as 那个就是jiùshì"like, I mean" — reformulating嗯 — the pure "um"嗯 is the vocalized pause with no lexical content at all — just the sound of thinking. (The same syllable, said with a falling then flat contour, also works as the backchannel "mm-hm / yeah" that shows you're listening.)
嗯……我想想。
èn…… wǒ xiǎngxiang
Um… let me think. (informal)
嗯，对，就是这样。
èn, duì, jiùshì zhèyàng
Mm, right, exactly. (informal) — 嗯 here as an agreeing 'mm-hm.'
那个 / 这个 — "uhh…" while you hunt for the wordThis is the heart of the page. As a filler, 那个 has nothing to do with "that." It's a placeholder you utter while the real word is still loading, precisely like English "uh…" or "the… you know…". 这个 does the same. And because it's a stall, speakers repeat it — 那个那个 — which is normal disfluency, not two demonstratives.
那个……你能不能帮我一下？
nàge…… nǐ néng bu néng bāng wǒ yíxià?
Uhh… could you help me for a sec? (informal)
这个……怎么说呢？
zhège…… zěnme shuō ne?
This… how should I put it? (informal)
那个那个，你上次说的那件事，后来怎么样了？
nàge nàge, nǐ shàng cì shuō de nà jiàn shì, hòulái zěnmeyàng le?
Uh, uh — that thing you mentioned last time, how did it turn out? (informal) — the opening 那个那个 is filler; the later 那件事 is the real demonstrative.
The two uses can even sit back to back — a filler 那个 stalling for the very phrase that then arrives with a real demonstrative:
我想买那个……那个红色的包。
wǒ xiǎng mǎi nàge…… nàge hóngsè de bāo
I want to buy that… uh… that red bag. (informal) — first 那个 = filler, second 那个 = 'that' + noun.
就是 — "like, I mean"Stretched-out 就是 (sometimes 就是说) fills a pause while you rephrase or reach for the right words — the Chinese "like…" or "I mean…".
就是……我也不太确定。
jiùshì…… wǒ yě bú tài quèdìng
It's like… I'm not too sure myself. (informal)
Two more you'll hear constantly: 呃 (è), a nasal "errr" that's close kin to 嗯, and the phrasal filler 怎么说呢 (zěnme shuō ne) "how should I put it," which buys a whole beat while you reformulate — the Chinese equivalent of trailing off with "how do I say this…". None of these carries meaning; they're the audible sound of a sentence still under construction.
呃……我一下子想不起来他叫什么。
è…… wǒ yíxiàzi xiǎng bù qǐlái tā jiào shénme
Errr… I can't remember his name for a second. (informal)
怎么说呢，这件事有点复杂。
zěnme shuō ne, zhè jiàn shì yǒudiǎn fùzá
How should I put it… it's a bit complicated. (informal)
The 那个 pronunciation note — completely innocuousTwo things worth knowing about how filler 那个 sounds. First, in casual speech it's very often read nèige rather than nàge — the same colloquial vowel shift you meet across northern spoken Mandarin and erhua. Second, and this catches many English-speaking learners off guard: repeated nèige nèige can, to an English ear, resemble a notorious English slur. It is completely innocuous filler in Chinese — nothing more than "uh, uh." Knowing this spares you both the misunderstanding of a Chinese speaker and the impulse to read offense into an ordinary pause.
💡Register warning: 嗯 / 那个 / 这个 belong to casual speech only. In a job interview, a formal presentation, or anything written, they read as unpolished. The professional fix isn't a different filler — it's a silent pause. A confident half-second of quiet beats a string of 那个那个 every time.Common Mistakes1. Hearing filler 那个 as "that (thing)" and hunting for a referent. At a hesitation point, 那个 is just "uh"; there's nothing to look for.
❌ 听到 “那个……我们走吧”，去找 “那个” 指的是哪个东西。
Mis-parse — here 那个 is filler ('uh…, let's go'), not the demonstrative; there is no object it points to.
✅ 那个……我们走吧，快迟到了。
nàge…… wǒmen zǒu ba, kuài chídào le
Uh… let's go, we're about to be late. — 那个 = 'um', no referent.
2. Using 嗯 / 那个 in a formal presentation or interview. They mark unplanned casual speech; in formal settings, pause silently instead.
❌ 各位好，那个，今天我想讲一下，嗯，我们的新计划。（正式发言）
Register clash — fillers make a formal talk sound unprepared; cut them: 各位好，今天我想讲一下我们的新计划。
✅ 各位好，今天我想讲一下我们的新计划。
gèwèi hǎo, jīntiān wǒ xiǎng jiǎng yíxià wǒmen de xīn jìhuà
Hello everyone, today I'd like to talk about our new plan. (formal — no fillers)
3. Writing the fillers into text (essays, formal emails). They're speech-only disfluency; don't transcribe them into writing.
❌ 嗯，那个，我写信是想问一下……（正式邮件）
Speech-only — 嗯 / 那个 don't belong in a written email; drop them: 您好，我写信是想问一下……
✅ 您好，我写信是想问一下报名的事。
nín hǎo, wǒ xiě xìn shì xiǎng wèn yíxià bàomíng de shì
Hello, I'm writing to ask about registration. (formal — email)
4. Thinking filler 那个 is rude or a slur. It carries zero offensive meaning in Chinese — it's the plain equivalent of "uh."
❌ 因为 “那个” 听起来像英语里的某个词，就以为说话人在骂人。
Misconception — filler 那个 (nèige) is innocuous 'uh'; the resemblance to an English word is pure coincidence and means nothing.
✅ 那个……让我再想一下。
nàge…… ràng wǒ zài xiǎng yíxià
Uh… let me think about it a bit more. — ordinary, harmless filler.
Key Takeaways嗯 / 那个 / 这个 / 就是 are pure hesitation fillers — the "um, uh, like, I mean" of Chinese, buying you thinking time.Filler 那个 is NOT the demonstrative "that" — it has no referent, and repeating it (那个那个) is normal disfluency, not two "thats."In casual speech 那个 is often read nèige; despite sounding like an English slur to some ears, it is completely innocuous.These are casual-speech only — in formal talks and in writing, a silent pause replaces them; never transcribe them into an essay or email.They differ from the interactive stance tags 你看 / 我觉得, which actually carry a function.
