The Real Secret to Sounding Fluent? It’s Simpler Than You Think!
By Geralde Vincent-Bancroft
When I first started learning Italian, I had a notebook filled with what I called “genius words.” These were long, impressive-sounding vocabulary words I was determined to drop into conversation. I thought that using words like incommensurable (incommensurabile) would make me sound like a native. Instead, I often got blank stares. I was so focused on finding the perfect, complex word that my speech was slow, hesitant, and full of awkward pauses. It was the opposite of fluent.
It turns out my whole approach was backward. Many of us believe that a big vocabulary is the key to fluency, but what if I told you the real secret is mastering the simple, everyday phrases you hear all the time? Recent research confirms this, and it’s a game-changer for language learners everywhere.

The Science of Sounding Smooth
Let’s dive into some fascinating research from Waseda University in Japan. A study led by researchers Kotaro Takizawa and Shungo Suzuki looked at what actually makes a non-native speaker sound fluent to others. They analyzed the speech of 102 Japanese speakers of English, paying close attention to their use of “formulaic expressions.”
What are those? They’re the common, multi-word phrases that native speakers use without even thinking. Think of phrases like:
- “on the other hand”
- “by the way”
- “I see what you mean”
- “as a matter of fact”
The researchers had experienced raters listen to the speeches and judge the speakers’ fluency. The results were clear. The single biggest factor was “utterance fluency”—how smoothly the person spoke, with minimal pauses and corrections. But here’s the exciting part: the use of common, high-frequency phrases had a noticeable, positive impact on how fluent the speakers were perceived. Using rare, sophisticated words? It made almost no difference.
This tells us something huge: fluency isn’t about showing off your vocabulary. It’s about communicating smoothly and naturally, and common phrases are a powerful tool to help you do just that.
Why Common Phrases Are Your Fluency Superpower
So, what makes these simple phrases so effective? It all comes down to how our brains handle language.
1. They Reduce Your Brain’s Workload
Think of formulaic expressions as pre-built language blocks. When you learn “I agree with you” as a single unit, your brain doesn’t have to assemble it from scratch every time. It just pulls the whole block off the shelf. This frees up mental energy, allowing you to focus on your main message instead of worrying about grammar rules. The result? You speak more quickly and with fewer hesitations.
2. They Make You Sound More Natural
Native speakers use these phrases constantly. They are the connective tissue of conversation. When you start using them, you’re tapping into the natural rhythm and flow of the language. Instead of saying something slightly off, like “I agree the idea,” you use the natural-sounding “I agree with the idea.” This small change makes a big difference in how you’re perceived. It signals to the listener that you have a good feel for the language.
3. They Help You Avoid Errors and Pauses
Have you ever stopped mid-sentence because you couldn’t find the right word or preposition? Using formulaic expressions helps you bridge those gaps. Phrases like “in my opinion” or “for example” act as smooth transitions, keeping your speech moving forward and reducing those awkward, fluency-killing pauses.
Your Action Plan for Effortless Fluency
Ready to put this into practice? The best part is that you can start right now, no matter your level.
- Become a Phrase Detective: Start actively listening for these common phrases. Watch movies, listen to podcasts, and pay attention during conversations with native speakers. Keep a running list in a notebook or a notes app on your phone.
- Focus on Chunks, Not Just Words: When you learn new vocabulary, don’t just memorize the word. Learn it in a common phrase. Instead of just learning the word “look,” learn “look forward to,” “look after,” and “look out for.”
- Practice, Practice, Practice: Incorporate one or two new phrases into your speaking practice each day. Try using them when you talk to yourself, write in a journal, or chat with a language partner. The goal is to make them so familiar that they come out automatically.
- Embrace Simplicity: Give yourself permission to use simple language. Effective communication is the goal, not linguistic acrobatics. You’ll build confidence and sound more fluent by mastering the basics first.
A New Direction for Language Learning and Testing
This research has big implications beyond just individual learners. For language educators, it suggests a shift in focus. Instead of drilling students on endless lists of advanced vocabulary, teachers can help them master the common expressions that will have a more immediate impact on their communicative ability.
It’s also relevant for standardized tests like the TOEFL and IELTS, where fluency is a key component of your speaking score. Test-takers who can naturally weave these common phrases into their answers are likely to score higher, as they will sound more comfortable and polished.
So, let go of the pressure to sound like a walking dictionary. The path to fluency is paved with the simple, powerful, and incredibly useful phrases you hear every day. By making them your own, you’ll not only sound more fluent—you’ll feel more confident and connected in your new language.
