Filler words vs connectors: what’s the difference?

Filler words don’t change the meaning of a sentence; they’re vocalised pauses. The most common is euh (um). Connectors, on the other hand, express logical relationships like cause, consequence, or contrast.

Imagine starting a point: “Euh, je pense que…” (Um, I think that…) is a filler buying time. Now link your thought: “Je pense que c’est important parce que…” (I think it’s important because…). That’s a connector at work.

Mastering both turns halting speech into a smooth flow.

Essential French filler words

These tiny words give you a moment to collect your thoughts without pausing awkwardly. At B1, aim for neutral ones that fit most situations.

• Euh – the universal French hesitation sound. Euh, laisse-moi réfléchir. (Um, let me think.)
• Alors – can be a filler, often meaning “so” or “well”, especially at the start of a sentence. Alors, voilà ce que je propose. (So, here’s what I suggest.)
• Voilà – “there you go”; used to fill while you search for words or to conclude. Voilà, c’est fini. (There, it’s done.)
• Tu vois – “you see”; engages the listener and gives you a split second. C’est, euh, compliqué, tu vois. (It’s, um, complicated, you see.)

In casual conversation you’ll also hear bah (well) and du coup (so, therefore). However, these are highly informal. As a B1 learner, it’s smart to recognise them but use neutral fillers yourself. Pairing fillers with the right register is essential; dive deeper in our guide to French register.

Key French connectors to link your sentences

Connectors are the logical signposts that guide your listener. Here are the most useful ones for B1.

Function	Connector	Example	Translation
Cause	parce que	Je suis fatigué parce que j’ai mal dormi.	I’m tired because I slept badly.
Consequence	donc	Il pleut, donc je prends un parapluie.	It’s raining, so I’m taking an umbrella.
Contrast	mais	Elle est sympa, mais un peu timide.	She’s nice, but a bit shy.
Addition	et / de plus	J’aime le thé et le café. De plus, je bois de l’eau.	I like tea and coffee. Furthermore, I drink water.
Sequence	d’abord, ensuite, puis, enfin	D’abord on étudie, ensuite on s’amuse.	First we study, then we have fun.

Other handy connectors: car (because, more literary), puisque (since), c’est pourquoi (that’s why), pourtant (yet), cependant (however), sinon (otherwise). Note that car can’t start a sentence the way parce que can, making it less flexible in speech.

Register matters: from informal fillers to formal connectors

Everyday speech relies on straightforward connectors like donc and mais. But step into a formal essay or a professional presentation, and you’ll need more polished alternatives: par conséquent (consequently), néanmoins (nevertheless).

Fillers follow the same rule. Euh is universally acceptable in moderation, but bah and du coup belong to friendly chats, not job interviews. Overusing any filler can undermine your confidence, so in a formal setting, it’s often better to pause silently.

Getting register right across all your vocabulary is a skill worth building. Read our guide on formal vs informal French for practical tips. And if you find yourself in very casual company, you might encounter verlan, where words are flipped inside out-proof that register shapes everything.

Common mistakes with fillers and connectors

• Overusing euh. One every few sentences is fine; two in every sentence makes you sound uncertain. Practice pausing silently, then speaking.
• Confusing parce que and car. Both mean “because”, but car is more formal and often appears in writing or after a comma to justify a preceding statement. In everyday speech, stick to parce que.
  • Je reste à la maison parce qu’il pleut. (not car in conversation)
• Mixing alors and ensuite. Alors can mean “so” or be a filler, but for a clear sequence, use ensuite. J’ai mangé, et ensuite je suis sorti. Not et alors je suis sorti if you mean “then”.
• Using informal fillers in formal contexts. Reserve bah and du coup for casual talk; use neutral fillers or silence in a presentation.

How to practice and make them stick

Listen actively. Watch a French YouTuber or podcast and note every connector and filler you hear. You’ll quickly realise how often natives reach for these words.

**Shadowing. ** includes Shadowing, where you repeat after a native speaker. This trains your ear and mouth to use connectors at a natural pace.

Build step by step. Start with mais, donc, parce que. Every time you would pause, try slipping one in. Write a short paragraph describing your day using all three. Pick two connectors and challenge yourself to use them five times today in a virtual conversation.

Memory tip. Associate connectors with gestures: open palms for cause (parce que), a slicing motion for contrast (mais), and pointing forward for consequence (donc). Bodily cues help the words stick.
