How to remember the words you learn in another language

Almost everyone who studies a language knows the feeling: you learned a word on Monday, you recognised it on Tuesday, and by the following week it is gone. It is not a lack of talent. It is how memory works, and there are well-understood ways to work with it instead of against it.

Forgetting follows a pattern

In the nineteenth century, the psychologist Hermann Ebbinghaus measured how quickly he forgot material he had memorised, and found that forgetting is steep at first and then slows down. Much later research has confirmed the general shape: most of what is lost is lost soon after learning, unless it is reviewed.

The useful consequence is that the timing of review matters as much as the amount. Reviewing a word ten times in one evening does much less than reviewing it a few times spread over days and weeks.

Space out the reviews

Spaced repetition means reviewing each item just as it is starting to fade, and then waiting a little longer each time you remember it correctly: a day, a few days, a week, a few weeks. Words you keep getting right come back rarely; words you miss come back soon.

Done on paper, this is tedious bookkeeping. It is exactly the kind of thing software is good at, which is why most serious vocabulary tools schedule reviews per word rather than per lesson.

Recall, do not just reread

Rereading a list feels productive because the words look familiar. But recognising a word is much easier than producing it. Trying to recall the word before seeing the answer — even when you fail — strengthens memory far more than looking at it again. Researchers call this retrieval practice, and it is one of the most consistently supported findings in the study of learning.

In practice: cover the translation, say or write the word, then check. Getting it wrong is part of the method, not a sign it is not working.

Learn words inside sentences

An isolated word is fragile. The same word inside a short, meaningful sentence comes with grammar, gender, the verb it goes with and a situation to hang it on. When you learn a new word, learn one sentence that uses it, ideally one you could imagine saying yourself.

For verbs, this matters even more. Knowing that a verb exists is not the same as being able to use it in the past tense in a real sentence.

Say it out loud

Pronouncing a word engages more than reading it silently, and it prepares you for the moment you actually need to say it. It also reveals the words you thought you knew but cannot pronounce, which are the ones that will fail you in conversation.

Little and often beats long and rare

Ten to fifteen minutes a day will do more than two hours on Sunday, for the same reason spacing works: each short session is a review at a better moment. Tie it to something you already do every day, so it does not depend on remembering to start.

In short

• Forgetting is fast at first: review soon, then less and less often.
• Recall the word before looking at the answer.
• Learn each word inside a sentence you could use.
• Say it out loud.
• A few minutes every day beats a long session once a week.

Poliglota schedules reviews word by word in this way, teaches words inside sentences and checks pronunciation on the device. But every idea here works just as well with paper cards and a pencil.
