Textbook French rarely mentions the small words that native speakers lean on constantly: the hesitation sounds, the sentence-openers, the little tags that don’t translate cleanly but carry real conversational weight. These fillers won’t show up on a vocabulary quiz, but recognizing them is the difference between understanding a textbook dialogue and understanding an actual French conversation. Here are the most common ones, what they mean, and how they’re really used.
Euh: The universal hesitation sound
Euh is the French equivalent of “um” or “uh”: a pure hesitation sound with no real meaning of its own, used while the speaker figures out what to say next. It’s extremely common in spoken French and almost never appears in writing outside of dialogue.
Il faut euh avoir euh une intention particulière. (“You have to, um, have, uh, a particular intention.”)
There’s no grammar to learn here. The only real skill is recognizing it instantly so it doesn’t throw off your comprehension when a native speaker drops two or three of them into a single sentence.
Alors: Starting a thought or reacting to news
Alors has two distinct jobs. As a straightforward time adverb, it means “then” or “at that time”:
Il était alors directeur d’une petite agence. (“At that time, he was the manager of a small agency.”)
But at the start of a sentence, alors shifts into a filler role that matches “so” in spoken English almost exactly: opening a new thought, reacting to what someone just said, or signaling that a question or conclusion is coming. There’s usually a slight pause after saying the word, just like you often hear when someone starts a sentence with “So…” in English.
Alors, quoi de neuf ? (“So, what’s new?”)
Alors, qu’est-ce que tu en penses ? (“So, what do you think about it?”)
This sentence-opening use is just as frequent in spoken French as “so” is in spoken English, which makes it one of the first fillers worth internalizing.
Donc: Not just “therefore”
Learners meet donc as the word for “therefore,” used to show a logical consequence, and that’s true:
Elle étudie donc elle réussit à tous ses examens. (“She studies, so she passes all her exams.”)
But donc also shows up doing two other jobs that have nothing to do with logic. First, it can add stress to a command or question:
Écoute-moi donc ! (“Do listen to me!”)
Allons donc ! (“Come on!”)
Second, it can register surprise at something, closer to “so” in “so he was a spy?” than to any logical connector:
C’était donc un espion ? (“So he was a spy?”)
Once you notice this stress-and-surprise use, you’ll start hearing donc constantly in places where a literal “therefore” makes no sense.
Ben: The casual “well”
Ben is a spoken-register variant of bien, used the way English speakers use “well” to open a sentence, hedge an answer, or buy a half-second before responding.
Ben, je ne sais pas trop. (“Well, I don’t really know.”)
It belongs firmly to casual spoken French. You won’t see it in formal writing, but it’s one of the most frequent words in ordinary conversation.
Voilà: Closing a thought
Everyone learns voilà as “here is” or “there is” for pointing something out, but in conversation it also works as a verbal “period,” a way to signal that a point has been made or an explanation is finished.
On est arrivés en retard à cause de la circulation, voilà. (“We got there late because of traffic, that’s it.”)
Used this way, it functions less like a translation of any single English word and more like a verbal shrug that wraps up whatever was just said.
Tiens: Reacting with surprise
Tiens is the imperative form of tenir (“to hold”), but as an interjection it’s used the way English speakers use “oh” or “well” to react to something unexpected.
Tiens, je ne m’attendais pas à te voir ici ! (“Oh, I didn’t expect to see you here!”)
It also shows up when handing something to someone, closer to “here you go,” so context does most of the work in telling the two uses apart.
Hein: The casual tag question
Hein tacked onto the end of a sentence works like “huh?” or “right?” in English: a quick check that the listener is following along or agrees.
C’est un bon film, hein ? (“It’s a good movie, right?”)
It’s the informal cousin of the more formal tag n’est-ce pas, and it shows up far more often in everyday speech than its textbook counterpart does.
Quoi: The sentence-ending shrug
Beyond its role as the informal, stressed form of “what” (Tu veux quoi ? instead of the more formal Qu’est-ce que tu veux ?), quoi also gets tacked onto the end of a statement in casual speech, adding a note of “you know” or “I mean” without changing the literal meaning.
Elle a raison, quoi. (“She’s right, you know.”)
This use is casual and conversational. It doesn’t add information so much as tone, closing off a statement the way a shrug would.

Next Steps
These fillers are part of a bigger gap between the French taught in textbooks and the French people actually speak. Our post on French idiomatic expressions covers the everyday phrases that fill the same gap, and French idioms and common expressions is a good next stop for the core reaction phrases that come up constantly in conversation.
None of these fillers stick from a list alone. They’re rhythm and habit, which means the fastest way to make them automatic is hearing and using them in live conversation. A platform like italki connects you with native French tutors who use words like alors and donc constantly without thinking about it, which is exactly the kind of exposure that makes them click.
