How to actually learn vocabulary

Most vocabulary study fails, and it fails in a predictable way. Here is what goes wrong and what to do instead.

Why word lists do not work

A list gives you a word and a translation. What it does not give you is:

• What goes with it. You can know mistake and still write do a mistake.
• How formal it is. Purchase, buy and pick up all mean the same thing and belong in different places.
• What form it takes. Succeed, success, successful, successfully.
• Whether it is normal. Dictionaries list rare words next to common ones with no signal.

So you end up recognising a word on a page and being unable to use it. That gap is the whole problem.

Record chunks, not words

Never write down a single word. Write down the phrase it appeared in.

```

✗ decision

✓ make a difficult decision

✗ apply

✓ apply for a job / apply to a university

```

The chunk carries the grammar, the preposition, and the partner word all at once, and you learn them together for the same effort.

Space the repetition

Reviewing something the moment before you forget it is far more effective than reviewing it while you still remember. Rough intervals: one day, three days, a week, three weeks, three months. Any flashcard tool that schedules this will do, and paper cards in labelled boxes work fine.

Aim for use, not recognition

Two different abilities:

• Passive: you understand it when you read it.
• Active: you produce it when you need it.

Passive vocabulary is typically several times larger. Moving a word from one to the other takes using it, deliberately, several times. Pick five words a week and force them into something you write.

Learn the family

One root gives you four or five words for very little extra effort.

The frequency point

The most common 2,000 words cover roughly 80% of ordinary English text. The next 1,000 add a few percent more. A rare word you found interesting will not repay the effort the way a common one will.

If you have limited time, the highest-value work is not learning more words. It is learning what the words you already have go with, which is what the next lesson is about.
