Why vocabulary is the one thing you can't cram

Why it behaves differently from everything else

Maths can be taught. There is a method, you learn the method, you can do the questions. A child who cannot do long division in March can do it by May.

Comprehension can be practised. The skills are transferable, and a child who learns to find evidence in a passage gets better at finding evidence in any passage.

Vocabulary does neither. A word is not learned by being explained once. It is learned by being met repeatedly, in different sentences, over weeks — until the meaning arrives before the definition does.

That is why the word list taped to the fridge disappoints. A child can learn that audacious means “bold and daring” and still not recognise it in a sentence, still not use it, still lose the mark. Recognising a definition and knowing a word are different things, and only one of them is tested.

One gap, three costs

Here is why a single unknown word matters more than it looks. A child meets audacious in a paper.

First, they lose the vocabulary mark. That much is obvious and it is the smallest of the three.

Second, if the word appeared in a comprehension passage, they have now slightly misread the passage. Not badly — they will guess from context and often guess close — but the questions that turn on precise meaning are now guesses too.

Third, and worst, they lose time. A child who is unsure re-reads. Re-reading costs minutes, and minutes at the end of a timed paper are questions not attempted.

One weakness, three sets of marks. This is why vocabulary punches above its allocation on the mark scheme.

What actually builds it

• ●Reading, first and by a distance. No structured programme comes close to volume of reading, because reading supplies exactly what words need: repeated encounters, in real contexts, spread over time.
• ●Meeting the word more than once, spaced out. A word seen today, again in four days and again in a fortnight sticks. The same three encounters crammed into one evening do not.
• ●Using it, not just recognising it. Ask a child to use a new word about somebody they know and you find out immediately whether they have it. “My brother was audacious” — do they mean bold, or do they mean naughty?
• ●Going after the half-known words. The words worth your time are the ones they nearly know: humble guessed as “shy”, diligent as “clever”, reluctant as “scared”. Close enough to feel right, wrong enough to cost the mark. There are more in our commonly confused 11+ words.

What does not build it

• ●Lists learned by definition. They produce children who can recite meanings and cannot recognise the word in a sentence.
• ●Cramming in the final month. A word met for the first time three weeks before the exam will not be reliably there on the day, and the hour spent on it was an hour not spent consolidating something they nearly know.
• ●Assuming it will come. It does come, through reading — but on its own schedule, and if your child is not reading much, it is not coming.

What this means for timing

Vocabulary is the argument for starting earlier than you otherwise would. Everything else in the 11+ responds to effort in the last six months. Vocabulary responds to effort over years, and the effort is mostly reading.

If your child is in Year 4 and you are wondering what to do, this is the answer: this, quietly, for a long time.

This is the problem Wordrealm was built around — words met repeatedly, spaced out, inside stories rather than on lists. But the principle holds whether you use anything of ours or nothing at all: repeated meetings, spread out, in context.
