Making New Words Stick

Why words disappear

You learn a word on Monday. On Tuesday you remember it. By Friday it's gone, or it's on the tip of your tongue and won't come out. This happens to everyone, in every language, and it's not a sign of a bad memory. Memory keeps what it thinks you'll need and drops the rest. A word you met once, in a list, with no use attached, looks like something you won't need.

So the job isn't to try harder to remember. It's to send your memory stronger signals that this word matters. There are four signals that work well.

Signal one: meet it again, at the right time

Seeing a word ten times in one evening is less useful than seeing it five times over two weeks. Each time you almost forget and then recall it, the memory gets stronger. This is called spaced review, and it's the most reliable way to keep vocabulary.

A basic schedule works: review a new word the next day, then after three days, then after a week, then after two or three weeks. Each review takes a few seconds. Flashcard tools can manage the timing for you, but a notebook with dates works too. The key is that you try to recall the word before you look at the answer. Looking alone doesn't build much.

Signal two: say it out loud

A word you've only seen lives in your eyes. A word you've said lives in your mouth too, and it has more connections in your memory. That's why every sentence in the lessons and word pages comes with audio. When you review, say the word and a sentence with it, not only in your head.

This also fixes a common problem: knowing a word when you read it but not recognizing it when someone says it. If you've heard and said it, you'll catch it in speech.

Signal three: attach it to your life

Words stick when they're connected to something you care about. "Commute" is a list word until you say "My commute is forty minutes each way, and I hate it." Now the word is attached to a real feeling and a real place.

For every new word, write one sentence that's true for you. Your job, your city, your family, your plans. It takes thirty seconds, and it's worth ten repetitions of a sentence about someone else.

Signal four: use it for real

The strongest signal of all is using the word with a real person. When you use a new word in a conversation, your memory stores it with the whole situation: who you were talking to, how they reacted, whether it came out right. You'll often remember that moment years later.

This is why every lesson ends with a "Say it today" line. It gives you one piece of language to use for real, the same day. Do the same with your own new words: choose one each day and find a moment to say it.

Learn in pieces, not single words

All four signals work better when you learn a word with its partners. "Decision" is harder to remember than "make a tough decision", strange as that sounds, because the longer chunk has more to hold on to: a rhythm, a picture, a use. And when the moment comes to speak, the chunk comes out ready.

So, for each new word:

1. Hear it and say it, with a partner word.
2. Write one sentence about your own life with it.
3. Review it tomorrow, in three days, in a week and in two weeks, saying the sentence out loud each time.
4. Use it once with a real person.

Ten words a week handled this way will stay with you. Fifty words a week copied into a notebook mostly won't.
