Ever heard about the 10,000 hour rule?
It’s the idea that world class musicians and athletes spend at least 10,000 hours to master their skills.
In language learning, some people say that 10,000 words is the minimum number you need to be fluent.
The only problem is…
They’re both absolutely and utterly wrong.
So if you’re ever wondered how many words you need to know to be fluent in a language, today you’re getting the real deal.
I’ll show you exactly how to memorize 10,000 words. And more.
Let’s get started.
How Many Words Do You Need to Know to Be Fluent in a Language? The Answer
If you want to understand approximately 75% of what native speakers are talking about in everyday life, you’ll need between 1000-1200 words.
This is why to pass A2 on the CEFR test you’ll need knowledge of approximately 1000 words.
For some people, this is going to sound like a lot to cover. But the problem is this:
How exactly words are counted matters. Take the word “run” in English. Is it really just one word?
Not really. It’s also:
- To run
- To have run
There are other examples, such as dog becoming dogs, or cat becoming cats. A lot depends on the morphology, because in some languages, grammar will determine whether a new word needs to be used or not.
In sum, the number of words you need to learn to become fluent depends on two things:
- Your personal definition of fluency (a.k.a. your goal)
- And external testing structure like the CEFR
If you take the CEFR as your standard, which is not a bad idea, then C2 requires familiarity with 16,000 words.
Just keep in mind that how those words are counted will involve grammar. This means that you will often boost your word count simply by knowing how one word operates in different tenses.
How to Figure Out How Many Words You Truly Know
Think about your mother tongue.
How many words in the language can you recall right now?
Chances are that you would struggle to list all the words you’ve learned over the course of your lifetime.
The same thing will be true when learning a language. This is because active vocabulary consists of the words we use most often.
Passive vocabulary, on the other hand, involves words that have gone into reserve. We have to stretch to remember them because we use them less often. That, or we might undergo linguistic deskilling for a variety of reasons. For example, this happened to my English when I spoke primarily German for a few years.
In order to know how many words are active, there are a few things you can do.
Anki is a spaced repetition app that will help you track your recall rate.
It’s easy to use poorly, however, so be sure to check out my article on how to optimize your use of the tool.
If you use physical flashcards as part of your language learning efforts, you can simply count how many you answer correctly.
Three: Listening Tests
Throw on a podcast or movie in the language you’re learning.
Using a notebook, keep track of how many words you recognize.
There might be a catch with this kind of testing, however. If the movie or podcast is in a dialect you’re not familiar with, your accuracy count might not be accurate.
This can happen in your mother tongue too. For example, when watching Deadwood or The Witch, both of which use older forms of English, I sometimes didn’t recognize words or expressions, even though they are technically in my mother tongue.
Four: Reading Tests
As you read, keep a tally of how many words you understand. If you read at an especially high level, you can probably just count the amount of words on one line and multiply that by the number of lines on the page.
Four: Writing Tests
Every once in a while, sit down and compose an email to someone on a topic in the language you’re learning.
Pop it into a software that gives you word counts and you’ll instantly know how many words you wrote in that message.
You have to make an allowance for repetition, however. Definite and indefinite articles should be excluded from the count, for example.
Six: Record a Conversation
If you’re meeting with a language learning teacher regularly, you can record the sessions. Then, when you review the recording, count the words you know.
If you need tools for doing this, check out the part of my language learning software post where I talk about how I record my sessions and review them.
Seven: Review Your Memory Palace Networks
In the language learning parts of the Magnetic Memory Method Masterclass, you learn to use a special memory device called a Memory Palace.
Once it’s populated with vocabulary, it’s easy to know how many words you know. This is because you’ll have one word on each station.
At more advanced levels, however, you’ll memorize entire sentences on each station of your Memory Palace. That’s why the next strategy is the ultimate way to know how many words you know.
Seven: Sit for an Exam
If you really want to know where your level of fluency is at, arrange to take an exam. The CEFR makes it very easy to see how many words you’re capable of dealing with.
There are other exams you can pursue, depending on the language. When I sat for the level III Chinese exam, for example, it was based on the HSK system.
How to Become Fluent in Any Language Fast
The truth about fluency is that you simply want to be able to accomplish the goals that are important to you in the language.
For most people, you’ll want to shoot for B1, which is achievable within 6 months to a year. It will equip you with at least 2000 words.
Chances are that you’ll have a lot more than that, however, especially if you’re reading regularly in the language. After all, books are the ultimate spaced-repetition app.
But beyond reading, here are the steps you need to follow:
Lean Into Multiple Media
I’ve just mentioned the importance of reading. You also need ample doses of:
For the listening and reading component, check out my tutorial on using Netflix to learn a language.
Be Disciplined with Your Language Learning Material
Many people overwhelm themselves with too many options. They’re constantly hunting the Internet for the “magic bullet” that will finally help them learn the language they’re interested in.
It won’t happen.
Instead, you need to milk the materials you already have for all they’re worth.
To make progress much faster, limit yourself to:
- One video course
- One audio program
- One textbook
- One teacher
Stick with them until you’ve reached a milestone before moving on to the next.
Learn How to Associate
The fastest way to commit anything to memory is association.
This means that you take something unfamiliar and associate it with something you already know.
For a quick example of association, think of a word like “vocabulary.” Just pretend for the sake of this example that you don’t know it.
To use association to learn it, you would look at the first letter of the word. It’s a V so I’m going to think of a Vulcan named Spock. I would then have him tap his vocal chords while jumping into a cab.
What associations can you think up for the rest of the word?
Hint: It’s not always easy, but Ferris Bueller’s Day Off might help you.
Scale Your Vocabulary with Memory Palace Networks
The only problem with association is that it can be confusing and murky to figure out what association goes with what word.
That’s where the Memory Palace technique comes in.
Let’s say you have a Vulcan getting into a cab while tapping his vocal chords. He’s on his way to see Ferris Bueller’s Day Off at a theater next to a library.
Using the Memory Palace technique, you would place this association in a familiar location, such as on your living room couch.
If you get strategic about how you identify and create your Memory Palaces, it’s fun and easy to memorize thousands of words and phrases.
The fastest way to reach fluency is to make as many mistakes as you can.
Sadly, some would-be learners just can’t get past the embarrassment. That, or their egos are too strong.
But the reality is that making mistakes develops pattern recognition through comparison.
And of course, we need to realize that even as experts in our mother tongues, we still sometimes misspeak. Everyone has to make corrections from time to time.
To develop greater tolerance for making mistakes, it’s important to be relaxed during your learning sessions.
I recommend meditation and simple stretching exercises a few times a day. These activities are also good for your memory overall.
Fluency On Demand
Anyone can develop fluency.
And everyone should. The benefits of bilingualism are too good to ignore.
The trick is to let the numbers help you, not frustrate you.
The CEFR levels are probably the best indicator out there, and the best part is that you can practice for the texts without worrying too much about exactly how many words you know.
For many of us, numbers will serve as milestones that we use to chart our progress.
But frankly, I’ve never worried too much about it. Although I once counted that I know 1700 words in Sanskrit, this knowledge hasn’t added a shred to the ways that I use the language to create fulfillment in my life.
The same thing goes with using the Memory Palace technique you can learn with this FREE course:
I have created several hundred Memory Palaces. But the actual number isn’t nearly as important as the outcome of using them.
And that outcome has been tremendously useful. It’s helped me earn degrees, travel the world, and speak with the locals in their language while visiting many different countries.
So what do you say?
Are you ready to dive in and start learning more words in the language you dream of speaking fluently?
Make it happen!
