Why Are You Here?
You’re here because something doesn’t feel right.
Either you’re a parent watching your child work harder but sound “simpler,” or you’re a student who used to feel fluent — and now your vocabulary feels like it’s shrinking, your comprehension feels heavier, and your writing feels like it has lost its power.
Start here for our eduKate Vocabulary Learning System
This article exists to name what’s happening and to give you a map. Because most people don’t quit English from laziness. They quit because they have no bearings.
At eduKate, we call the main stall point the Vocabulary Transition Barrier: the moment where language becomes denser, but the foundation underneath isn’t automatic enough to carry it.
When that happens, students don’t just “learn slower.”
They start to feel like they are getting worse. The Vocabulary Transition Barrier
What happens when you forget words, or feel like you cannot express yourself (And What’s Actually Happening)
Vocabulary changes by stage
Most people talk about vocabulary as if it’s one straight line: learn more words, get better results. But vocabulary grows in phases, and each phase asks language to do a different job.
Kindergarten: naming the world
In Kindergarten, vocabulary is about naming objects, actions, feelings, and building simple meaning. This is where language becomes a child’s first map of reality.
Primary: stabilising everyday language
In Primary, vocabulary becomes about describing clearly, understanding common words deeply, and building automatic everyday language that can be used without strain. This is where “primary vocabulary” should become stable, fast, and fluent.
Secondary: compressed language begins
In Secondary, vocabulary starts compressing meaning. Words begin to carry relationships, causes, contrasts, conditions, and abstractions. This is where students hit the barrier if their foundation is not automatic enough. Why “Harder Words” Don’t Raise Marks
JC / Pre-U / High School: analysis and evaluation
Here, language becomes more analytical and evaluative. Students are expected to argue, weigh perspectives, qualify claims, and write with precision. This is the top of a major S-curve for many students.
University: adult language arrives, but “English class” disappears
University expects adult academic language — but it often stops explicitly teaching it. So many students plateau not because they can’t grow, but because there is no external force pushing vocabulary forward.
Adult career: professional language and credibility
Career vocabulary is not “fancy.” It is language that carries responsibility: clarity, persuasion, credibility, precision, and decision-making. The vocabulary load is real, but the “learning track” is usually invisible.
The S-curve: why growth feels slow right before it turns
Vocabulary growth is not linear. It moves in an S-curve: slow uptake, then a period of fast growth, then a plateau — until the next layer is built.
That’s why a student can be “fine” in one stage and suddenly feel lost in the next. They didn’t lose ability. They simply hit the top of one curve and stepped into the bottom of another.
And the bottom of a new curve always feels like: “I’m slow. I’m stuck. Nothing is happening.”
The S-Curve (Optimised Education)
Metcalfe’s Law: vocabulary grows like a network, not a pile
Most students try to grow vocabulary by collecting words. But vocabulary is not a pile of bricks. It’s a network.
When you learn a word properly, it connects to other words, to sentence structures, to contexts, to tone, and to ideas. The more connections you build, the more useful every new word becomes.
That is why vocabulary growth can suddenly accelerate — not because you found a better list, but because your language network reached a threshold where words start reinforcing each other.
The Fencing Method: how vocabulary becomes usable, not decorative
Vocabulary does not become powerful when you can define a word. It becomes powerful when you can control meaning inside a sentence.
The fastest way to make vocabulary real is to build sentences from simple to strong, step by step — so the student learns how words actually carry meaning, tone, and precision under pressure.
The modern layer: generations speak different English now
Vocabulary isn’t only divided by school stages. It’s also divided by generations and communities.
Gen Alpha slang, Gen Z internet language, Millennial shorthand, Gen X professional English — these are different “language worlds,” each with their own shortcuts, signals, and assumed context.
This is why vocabulary is no longer a simple 2D “formal vs informal” Venn diagram. It behaves like a 3D space: stage, domain, register, generation — all intersecting at once.
So sometimes what looks like “worsening vocabulary” is actually vocabulary splitting across worlds:
- one set for school performance
- one set for social belonging
- one set for internet compression
- one set for adult credibility
Without a map, people mistake this complexity for regression.
What this article will do for you
This article gives you a single thread through the whole journey: Kindergarten → Primary → Secondary → JC/Pre-U → University → adult career — including the generational layer that complicates everything.
It will show you why “harder words” don’t automatically raise marks, why effort can feel wasted when the foundation isn’t stable, and why starting a new stage always feels slow — even when you’re about to turn the curve.
Start here for the full framework
eduKate Vocabulary Learning System
And here for the deeper base logic
First Principles of Vocabulary (No one talks about this)
If you feel like your vocabulary is getting worse, it’s rarely because you “forgot words.”
It’s usually because you crossed an invisible line where language changes shape — and nobody told you the rules changed.
Your English didn’t disappear. The weight per sentence increased.
This is what we call the Vocabulary Transition Barrier: The Vocabulary Transition Barrier
The illusion: “I’m getting worse.”
The reality: you’re facing denser language.
In earlier years, language is mostly direct:
- concrete words
- familiar situations
- short chains of meaning
Later, language becomes compressed:
- abstract words
- cause-and-effect inside one sentence
- subject-specific terms that carry hidden assumptions
So the student reads and thinks:
“I know these words… why can’t I understand this?”
Because recognising a word is not the same as holding its meaning inside a moving sentence.
That’s not regression. That’s a new layer.
You didn’t lose vocabulary. You lost ease.
The biggest change is not the number of words you know.
It’s how fast you can access them.
A word is only useful when it becomes automatic:
- you recognise it instantly
- you recall it without strain
- you can use it in a sentence without “thinking about the word”
When language gets denser, the exam doesn’t wait for your brain to warm up.
So your mind starts spending effort decoding, and suddenly:
- reading feels tiring
- comprehension feels slippery
- writing becomes simpler and shorter
- you avoid “big” words because they don’t obey you
That feels like “worse vocabulary,” but it’s actually slower vocabulary under higher load.
Why studying more can make you feel worse
This part shocks parents and students.
Sometimes the more you “study vocabulary,” the worse you feel — because you’re collecting words in the wrong form.
1) You’re collecting words like decorations
Lists teach recognition. Exams demand control.
Students can “know” a word on a list but cannot:
- choose it under pressure
- fit it into a sentence naturally
- adjust it to tone and context
So they keep collecting and still feel stuck.
That’s not lack of effort. That’s wrong format.
2) You’re learning secondary vocabulary without stabilising primary vocabulary
Primary vocabulary is not “easy words.”
It is the everyday language that must become effortless so your brain has spare capacity for harder ideas.
If primary vocabulary is shaky, secondary vocabulary doesn’t stack — it collapses.
That’s the heart of this problem: The Vocabulary Transition Barrier
3) Your awareness improved first
This is a quiet psychological trap.
When you grow a little, the first thing that improves is not performance — it’s accuracy of self-judgement.
You start noticing gaps you never noticed before.
So it feels like you’re getting worse, but you’re actually becoming more honest and precise about what you can and can’t do.
That’s growth — just uncomfortable growth.
What “worsening vocabulary” looks like in real life
This is the pattern we see again and again:
- You understand when someone explains, but you can’t explain it yourself.
- You can read a paragraph, but you can’t summarise it cleanly.
- Writing feels “childish” because you can’t express complex thoughts.
- Comprehension becomes guessing instead of reasoning.
- Science and Math start feeling like English problems.
- You feel tired earlier because every sentence costs more mental energy.
That’s not a character flaw.
That’s language load exceeding language foundation.
The deeper idea: vocabulary is not memory — it’s infrastructure
Most people treat vocabulary as a storage problem:
“I need more words.”
But school treats vocabulary as a thinking problem:
“I need words that can carry relationships, causes, contrasts, conditions, and evaluations.”
That’s why secondary vocabulary is so dangerous when it appears too early:
it turns language into a bottleneck for every subject.
Vocabulary becomes the hidden gatekeeper of:
- comprehension
- writing
- answering technique
- speed
- confidence
- willingness to try
So when vocabulary “gets worse,” it’s often not about English marks.
It’s about the child losing control of meaning.
Why the S-curve explains everything
Vocabulary growth isn’t smooth. It’s an S-curve:
- slow in the beginning
- then suddenly fast
- then it plateaus again until the next leap
If you don’t know this, you interpret the slow phase as failure.
But the slow phase is often just foundation stabilising.
Once enough foundation locks in, growth accelerates.
That’s why we frame learning as an S-curve process: The S-Curve (Optimised Education)
Why “harder words” don’t raise marks
A student can memorise “sophisticated” words and still write worse.
Because what raises marks is not word difficulty.
It’s clarity, control, and accuracy.
Hard words without control create:
- awkward phrasing
- incorrect usage
- broken logic
- forced tone
So the student becomes scared of writing, and chooses safer language.
That’s why we wrote this explanation: Why “Harder Words” Don’t Raise Marks
The sentence that changes the whole experience
Most students don’t quit because they are weak.
They quit because they have no road signs.
A system prevents quitting by giving cues:
“This is why we’re learning this.”
“This is the next step.”
“This is how you know it’s working.”
So here is the sentence that matters:
Confusion is a signal. We will resolve it.
Not comfort. Not excuses. Not fog.
Direction.
The bigger picture
This is not just a vocabulary issue.
It’s a modern education issue:
we normalised students sitting in confusion, and then we act surprised when growth stops.

One final calibration
If vocabulary feels like it’s getting worse, don’t ask:
“What’s wrong with my child?”
Ask:
“What changed in the language demand — and did we build the foundation required for it?”
Because most of the time, the child is not failing.
They’re simply standing at the edge of a new layer — waiting for someone to show them the map.
The next transition: Secondary → Adulthood (and why vocabulary can plateau in University)
The Vocabulary Transition Barrier doesn’t end at Secondary school.
It repeats again when a student steps into University, and later into adult life — except this time, the problem is quieter, because the “English subject” usually disappears.
In most systems, English is pushed hard up to JC / Pre-U / High School, then it becomes optional, assumed, or “already done.” University expects adult language, but it rarely teaches adult language as a structured track. So many people enter University thinking:
“I’m fine. I got through school English.”
Then they hit adult language demands and realise something feels… slower again.
Adult language is not just “more words.” It’s a different job.
Adult vocabulary isn’t about fancy synonyms.
It’s language that carries:
- precision (saying exactly what you mean)
- argument (claim → evidence → implication)
- abstraction (principles, frameworks, models)
- professional tone (credible, calm, controlled)
- compression (more meaning per sentence, fewer wasted words)
This is why University reading can feel like a wall even for “good students.” It’s not harder because the topic is hard. It’s harder because the sentences carry more stacked meaning.
Why vocabulary plateaus after JC / Pre-U / High School
School creates a built-in push.
Exams force reading. Writing rubrics force structure. Teachers force vocabulary exposure.
But once that system ends, two things happen:
- There is no external force pushing vocabulary forward.
- Many people switch to coping strategies: skimming, relying on slides, memorising, avoiding difficult texts, staying inside their comfort language.
So vocabulary growth can plateau not because the person is incapable, but because the environment stops demanding structured language development.
The S-curve explains this adulthood plateau perfectly
From the earlier idea: vocabulary grows like an S-curve.
By JC / Pre-U / High School, many students reach the top of that curve:
- they can handle school-level comprehension
- they can write within exam formats
- they can survive academic tasks
But University is a new curve.
It requires a new layer of vocabulary: discipline language, research language, professional language, argument language.
If you don’t deliberately stack a new S-curve on top of the old one, the “lego tower” stops growing.
And here’s the cruel part:
When you begin the next curve, you are back at the bottom again.
So it feels like:
“I’m slow.”
“I’m not improving.”
“Everyone else is smarter.”
“I’m reading but nothing sticks.”
That feeling is not failure.
That is simply what the bottom of a new learning curve feels like.
Why it feels directionless in University
In school, teachers tell you what words matter:
- vocabulary lists
- model essays
- comprehension techniques
- set texts and themes
In University and adulthood, the problem becomes:
You might not know what words you need next.
You’ve stepped into a new world:
- new discipline (psychology, business, engineering, law)
- new social settings
- new professional expectations
- new ways of reasoning
But no one hands you the vocabulary map.
So you can end up learning “random words” without building a working system — and the growth feels invisible.
What this looks like in real adult life
This is how the adulthood version shows up:
- You understand lectures, but struggle to read journals or long articles.
- You can speak casually, but struggle to write professionally.
- You can explain ideas to friends, but can’t structure arguments clearly in writing.
- You avoid “serious reading” because it feels tiring.
- You feel like your vocabulary is “stuck” at a certain age.
That’s not laziness.
That’s the absence of a new curve.
The key idea: adulthood requires deliberate vocabulary stacking
If Secondary → JC is one vocabulary curve, then:
University is the next curve.
Work and professional identity is the next curve.
Leadership, persuasion, and influence is the next curve.
If you don’t stack curves, you don’t grow — not because you can’t, but because nothing is forcing the next layer to form.
And when you do start, you will feel “slow” again.
That’s normal.
The mistake adults make is interpreting “bottom of the curve” as:
“This is my limit.”
It isn’t.
It’s just a new beginning.
One last calibration for adults and parents
If your teenager is entering University, or if you’re an adult who feels your English plateaued, don’t ask:
“Why am I not improving?”
Ask:
“What is my next vocabulary curve — and what kind of language does my next world require?”
Because vocabulary doesn’t only belong to school.
Vocabulary is how you build adulthood.
Now adulthood, we have a whole new set of problems.
The hidden layer nobody talks about: generational vocabulary (why language is 3D, not 2D)
There is another reason vocabulary can feel like it’s “getting worse” — even when you’re reading more and learning more.
It’s not just that school language gets harder.
It’s that different generations are literally running different vocabularies at the same time.
Gen Alpha slang does not map cleanly onto Millennial or Gen X language. So a Gen X adult can hear a Gen Alpha kid say something like “67” or “jeet” and feel completely locked out — not because the child is speaking “bad English,” but because the word is operating inside a different shared context.
Why a Venn diagram is not enough
Most people think vocabulary differences are a 2D problem, like a Venn diagram:
“School words” vs “home words.”
“Formal English” vs “casual English.”
But modern vocabulary is not just two circles overlapping. It behaves like a 3D map (and honestly, sometimes 4D), because meaning depends on multiple axes at once:
1) Domain: what world you’re in (school, gaming, sports, social media, science, literature, work).
2) Register: what the word is doing (formal explanation, casual bonding, joking, sarcasm, signalling identity, commanding attention).
3) Tribe + time: which community and which generation is using it (Gen Alpha vs Gen Z vs Millennial vs Gen X) — and which “era” of the internet it comes from.
So the meaning of a word is not a single dot on a flat page. It’s a coordinate inside a space.
That is why two people can both speak English, both be intelligent, and still feel like they are speaking different languages.
Example: why “67” breaks adults
To an adult, 67 is just a number.
To Gen Alpha, “6-7 / 67” became a viral meme and a social signal — a burst of energy, a playful interjection, sometimes connected to basketball edits and sometimes used with no fixed meaning at all. In other words: it’s not “a word you look up.” It’s a token that carries shared internet context.
If you don’t share the context, you don’t get the meaning. And that’s the point: it works as bonding language inside the group.
Example: why “jeet” can confuse everyone (and why this matters)
“Jeet” is a good example of why vocabulary is 3D.
In some communities it is simply a clipped, spoken contraction of “Did you eat?” (“Jeet yet?”). In other places online, the same spelling can carry totally different meanings.
So the issue isn’t just generation. It’s community + region + platform.
Adults often assume: “If I don’t understand it, it must be nonsense.”
But what’s actually happening is: the word is living at a different coordinate than the one you’re standing in.
Why Gen Alpha slang is not “bad vocabulary” — it’s ultra-compressed vocabulary
Here’s the twist that most people miss.
Gen Alpha slang is often more compressed than adult language. It can pack an entire reaction, mood, meme, and social signal into one tiny token.
That is not “no vocabulary.”
That is vocabulary doing a different job: signal, identity, belonging, speed.
So when parents say “my child’s vocabulary is getting worse,” sometimes what they’re seeing is not vocabulary shrinking — but vocabulary splitting into different dimensions:
- One vocabulary for school and grades.
- One vocabulary for peers and social belonging.
- One vocabulary for internet culture and compressed signals.
The problem appears when a student becomes fluent in the social-code layer, but does not build the academic-language layer high enough to match school demands.
How this links back to the Vocabulary Transition Barrier
The Vocabulary Transition Barrier is not just “harder words.”
It’s the moment where your language foundation cannot carry a new kind of load.
And generational vocabulary makes this even more intense, because students are now switching between language worlds all day long.
So the goal is not to delete slang or shame it.
The goal is to help students become bilingual inside English:
They can keep their social language — while also gaining the academic vocabulary that lets them think, write, and perform under exam pressure.
