Levels of Language Proficiency: What Is Fluency?
I sometimes hear people say, in YouTube videos on language learning and elsewhere, that even with a few hundred words you can be fluent in a language, in other words that you can be fluent in a language even at a relatively low level of proficiency in the language.
What is fluency?

First of all, let’s look at this word ‘fluency’. Fluency is a bit like the word ‘good’ or ‘well’. If you say ‘I’m fluent in a language’, this is usually interpreted to mean you are very fluent. It’s the same as saying I speak X language well. It means that you speak it well. If you say ‘I speak the language quite well’ or ‘I’m quite fluent’, that actually suggests something less.

I once saw a video which wanted to make the case that we can be fluent with just a few words, by showing someone walking around town in Prague with limited Czech. This was supposed to prove that one doesn’t need many words to exchange pleasantries with shopkeepers, and thus one can be fluent with few words. But is this fluency? I don’t think so.
The European Framework of Reference

There are different ways of measuring levels of proficiency in a language. Perhaps the best general reference point is the European Common Framework of Reference which divides proficiency into six levels from A1, A2, B1, B2, C1 and C2. In my view, B2 is the level where you are fluent. If you look at the summary description below you will see that this level, sort of advanced intermediate, is actually quite high. It means you understand most situations, and can express yourself on a wide variety of subjects, albeit with mistakes.
The key points of this level are as follows.
•         Can understand the main ideas of complex text on both concrete and abstract topics, including technical discussions in their field of specialization.
•         Can interact with a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible without strain for either party.
•         Can produce clear, detailed text on a wide range of subjects and explain a viewpoint on a topical issue giving the advantages and disadvantages of various options.

Reading and fluency

I think that to be fluent, you have to be able to do certain things. Of course, you need to speak in a way that is comfortable for you and for the person you are talking to. But reading is a big part of getting to that level. To be fluent, you usually have to be able to read a newspaper. Now, in Chinese that might cause some difficulty because the writing system isn’t phonetic. So, conceivably, you could be fluent and not be able to read a newspaper, but in most situations someone who is fluent in a language should be able to read a newspaper comfortably, enjoyably, without struggling.

In English, newspaper English corresponds to a grade seven or grade eight vocabulary level. The biggest limiting factor of any content is the vocabulary level. You need quite a large vocabulary to do many things, to understand newspapers, radio news, to converse on subjects of interest etc.. In fact you need a larger vocabulary than what is needed just to read newspapers in order to be really fluent, in my view. In order to be able to call yourself fluent, you should also be able to read books. Perhaps not literature, although that would be good, but certainly books of non-fiction on subjects of interest to you. If you have that level of vocabulary and good comprehension, you can build your ability to speak, just by speaking a lot.
Fluency and vocabulary

A reliable indicator of fluency, or at least potential fluency, is the number of words you know. You still have to practice speaking, in fact you need to speak a lot in order to speak well. But to do that, to have meaningful conversations, you need a lot of words.

Some people want to claim it’s possible to be fluent with a limited vocabulary, that someone could be fluent with a grade three vocabulary level. That works if you are ten years old. But if you are an adult and you can only communicate with children, to my mind you’re less than fluent. If you can only talk about the weather and very basic things, even if you do so fluently, to my mind you’re not fluent.

Most adult native speakers have a large vocabulary–a large active vocabulary– in their own language. Certainly, the people that I would like to communicate with in any language I am learning, have large active vocabularies.

Therefore I have to have a fairly large passive vocabulary in order to understand what they’re saying, in order to engage with them in meaningful conversations. Fluency implies two-way communication. You can learn a few phrases using some memory technique and try to express yourself fairly quickly, but the trick is to understand what other people are saying. That is why I put so much emphasis on listening and reading, vocabulary and comprehension, as a key component of fluency, or at least potential fluency.

I always find this topic fascinating. When I was a five year old child, I was a chatty girl who could respond to everything around me just fine. Could I discuss the events of the world? No. But I would say I was fluent. Now fast forward decades later and I'm now a chatty woman. Can I discuss the events of the world? Yes. But I would say I'm still fluent.

So would fluency depend on how many words you know, or how comfortable you are with the tools you have?

Today I couldn't discuss nuclear science with a chemist. I wouldn't even know where to start, or understand a single thing about whatever they might throw at me. Does that mean I'm <em>not </em>fluent? I'd laugh if a chemist just dismissed me as someone not fluent in my own native language if I couldn't keep up with them in a conversation about whatever it is they research.

I think there is more than one way to determine fluency. Some people are stuck in their adult-minded ways of expecting to speak about many issues, but if it's not in your mental capability, does it mean you can't still be fluent? We're too hard on ourselves for wanting to be fluent when we keep raising the bar of what that's supposed to mean. So I think you're correct when you say B2 is fluent. At least... fluent enough.

For me, I think that to be fluent requires two things:

1) Can you express the ideas in your head, even if you must "work around" words that you might not know?

2) If you were forced to live in a country that speaks this language, and you would be forever stuck at your current level of speaking, would you be okay with that?

If the answer is "yes" to these two questions, I would say that basic fluency has been achieved.
But that is merely my personal opinion.
