"I Understand Everything, I Just Can't Speak."
Why this feeling is more common than you think, what’s actually behind it, and what to do about it.
I hear this from students often.
“Richard, my listening is fine. My reading is great. I understand everything. My problem is just speaking. I just can’t get the words out.”
Every time, I nod. Because I understand the frustration behind it completely. You have put in the hours. You have read, you have listened, you have studied. And yet the moment someone asks you a question in English, something freezes. The words that felt so available a moment ago suddenly feel very far away.
That experience is real. And the speaking practice you feel you need? You are right. You do need it. Speaking is a skill, and like any skill it needs to be practised regularly to feel natural.
But in my experience, there is usually something else going on underneath it. And once you see it, the path forward becomes much clearer.
The illusion of understanding
You are listening to a podcast in English. The host is talking about a topic you know well. You follow the general flow. You get the gist. You nod along. You feel like you understand.
What is actually happening is more like this: you understand enough to follow the general meaning. You catch the main ideas. Your brain fills in the gaps with inference, context, and prior knowledge. The experience feels like complete understanding because the gaps are being filled so seamlessly that you do not notice them.
This is not a failure. It is actually how listening works, even in your first language. Nobody processes every single word. The brain constantly uses context and prediction to fill in what it misses. But in your first language, the gaps are tiny. A missed word here, an unclear mumble there, filled in effortlessly from a lifetime of exposure. In English at the intermediate level, the gaps can be much larger than you realise. Whole phrases. Unfamiliar vocabulary. Grammatical structures your brain cannot quite parse at full speed. Your brain’s ‘inference engine’ papers over all of it, and the result feels like understanding.
Those gaps are often where the speaking problems live.
Why we overestimate
The brain genuinely believes it understood more than it did. Not because you are careless, but because the very skills needed to accurately assess your own comprehension are still developing. You do not have the reference point to know what you missed.
The intermediate learner who says “I understand everything” is not exaggerating. They genuinely feel that way. The feeling is just not always an accurate picture of what happened.
What understanding really means
Understanding is not binary. It is a spectrum.
At the surface level, you follow the general topic. You could tell someone “they were talking about their holiday,” but the specific details and exact words are hazy. This is what most learners mean when they say they understand everything.
A level deeper, you follow the specific points, the examples, the argument. You could summarise with reasonable accuracy.
Deeper still, you understand the meaning and you also notice how it was expressed. The vocabulary choices, the phrasal verbs, the idioms, the sentence patterns. This is where listening starts feeding speaking directly, because you are absorbing usable language, not just meaning.
And at the deepest level, everything lands with minimal effort. Tone, humour, subtext, cultural references. Near-native comprehension.
Most learners who tell me they understand everything are at the first or second level. That is real progress. But it is not the depth that produces natural, fluent speaking. For that, you need the third level and above, where the language itself is being absorbed, not just the meaning.
The connection to speaking
Here is why this matters for your speaking.
The words you produce come from the words you truly know. The patterns you generate come from patterns your brain has deeply absorbed. When speaking feels significantly harder than your comprehension suggests it should be, it usually means one of two things.
Either you have not had enough speaking practice to activate what you have learned. This is genuinely common, and it is a real part of the picture. Passive understanding and active production are different things. You can know a word perfectly well from reading and still find it does not arrive fast enough in conversation. That gap closes with practice, and it closes faster than most people expect once they start.
Or the comprehension is not quite as deep as it feels, and the vocabulary and patterns that feel familiar have not been absorbed deeply enough to be available on demand.
Most learners are dealing with both at once. Which means the solution is both at once too.
Deepening the listening
If you want to go deeper with your comprehension, the approach is less about more input and more about more attention.
Listen to the same content more than once. The first listen is for meaning. The second is where you start catching the language. The third and fourth are where specific words and phrases begin to embed themselves. If you have been listening to everything once and moving on, you have been skimming the surface.
Read and listen at the same time. Following a transcript while you listen on LingQ makes visible every word that was blurring past you in audio alone. You suddenly see how many words your brain was happily papering over. Those words become identifiable. That is where real comprehension deepens.
Notice the language, not just the meaning. When you listen, try to catch not just what is being said but how it is being said. The exact phrase someone used. The way a sentence was constructed. That noticing is what turns passive understanding into material your speaking can actually draw on.
Opening the tap
If your comprehension really is solid, if you genuinely are catching the language and not just the meaning, then the speaking is closer than you think. You have a full reservoir. You just have not opened the tap yet.
Glossika is a good place to start if speaking to a real person still feels like too much. You listen to real English sentences and repeat them, in your own space, with nobody watching. It gets your mouth moving and starts turning the patterns you have absorbed into something you can actually produce. By the time you sit down with a real person, the mechanics of speaking English are already warmed up.
When you are ready for that real person, iTalki is the easiest place to find someone warm and patient who is genuinely interested in what you have to say. You can also book a session directly with me if you would like a conversation rather than a lesson. With a solid comprehension base underneath you, the speaking tends to unlock faster than you expect once you give it regular opportunities to show up.
The first few sessions are the hardest. After that, the words start arriving with less effort. Not because something changed overnight, but because they were already there. They were just waiting to be called on.
Try This
Next time you listen to something in English, try a second listen with the transcript in front of you. Notice the moments where what you see on the page is different from what you thought you heard. Notice the words that blurred past. Notice the phrases your brain filled in rather than actually caught.
That is not failure. That is information. And it shows you exactly where a little more depth will pay off directly in your speaking.
Do you recognise this feeling? The sense that understanding and speaking feel disconnected? What has helped you bridge that gap?
If this post helped, a like lets me know and a restack helps it reach another learner who might need it.
