Fewer than you think, used better than you think

English has hundreds of thousands of words, and nobody knows them all. Educated adult speakers know tens of thousands, but they use far fewer in daily conversation. A small core does a huge amount of the work. The most common couple of thousand word families cover the large majority of what people say in everyday speech. The rest shows up rarely, one word here and one word there.

That's good news. It means the words that matter most for speaking are a list you can actually finish. It also means the question "how many words do I know?" is less important than "how well do I know the common ones?"

Knowing a word is more than knowing its meaning

You probably "know" the word "get". But do you know that people "get home", "get it" (understand), "get along" with someone, "get over" a cold, "get a text" and "get ready"? The common words are common because they do many jobs. Each job is worth learning.

Knowing a word well for speaking means you can:

Say it with the right stress, so people recognize it.

Hear it in fast speech, even when it's squeezed between other words.

Use it with its partners, the collocations that make it sound natural.

Use it in the right situation: "kids" with friends, "children" in a formal email.

A learner who knows two thousand words this deeply will usually speak better than one who knows eight thousand words from a list, with only a translation for each.

A rough map of levels

These numbers are approximate, and people argue about them, but they give you a sense of scale.

With a few hundred words and some set phrases, you can handle basic needs: ordering food, asking for directions, introducing yourself.

With a couple of thousand word families, known well, you can take part in most everyday conversations, with some gaps you work around.

With several thousand, you can follow films and news with less effort and talk about your work in detail.

Beyond that, the words become more specialized. You'll learn them from your job, your interests and your reading, not from general lists.

For most learners reading this, the first two stages are where speaking improves fastest.

Choose the right words

Not all words deserve the same time. Here's how to decide.

Frequency first. The Words & Collocations section is organized around the words people use most, with frequency lists for the core speaking words, word families, nouns, verbs, adjectives, adverbs, pronouns and prepositions. Start at the top of those lists.

Your life second. After the core, the most useful words are the ones for your own situation. A nurse in Sydney needs different words than a software developer in Bangalore. Collect the words you need for your job, your hobbies and your family.

Rare words last. If you meet a word you'll probably never say, understand it and let it go. You don't need to put it on a card.

Spend time on depth, not only breadth

Adding new words is exciting. Deepening old ones feels like revision. But for speaking, depth pays more. Once a week, take one common word you think you know, open its word page, and look at its partners. You'll almost always find a use you didn't know, and it'll be one you can use tomorrow.

A good balance for most learners is about ten new words a week, each learned with at least one partner, plus one familiar word explored in depth. That's slow on paper. In practice, it grows the vocabulary you can actually say.

Practice · 3 min

Check the depth of one common word.

  1. Choose one very common verb: get, take, make, have, go or put.
  2. Write as many different uses of it as you can in two minutes, each in a short phrase.
  3. Open its word page, if there is one, or listen for it in your next two lessons. Add any uses you missed.
  4. Pick the one new use you like best, write a sentence about your week with it, and say it out loud three times.

Say it today

Use it once in a real conversation before tomorrow. Out loud counts, even to yourself.
