You learn a list of new words, feel proud of yourself… and a week later most of them have vanished. It feels like your brain is working against you. In a way it is, but in a very predictable way.
That pattern has a name: the Ebbinghaus Forgetting Curve. Once you understand it, you can use it instead of fighting it.
Here is the curve in plain words, and how My Lingua Cards uses it in the background to bring your words back right on the edge of being forgotten.
What is the Ebbinghaus Forgetting Curve?
In the nineteenth century, the German psychologist Hermann Ebbinghaus ran experiments on how quickly people forget new information. The result was uncomfortable but useful: forgetting starts almost immediately. Twenty minutes after a study session a noticeable part of the list is already gone. After a day, much more of it has faded. After a week, little is left unless you came back to it.
Drawn on a graph, this looks like a steep slide: high at first, then a fast drop. That shape is the forgetting curve.
Your brain is not being lazy. It is saving energy. Information you never use again is treated as unimportant, so it goes.
Why this hits language learners so hard
Vocabulary is especially vulnerable. You learn ten new words in the evening. The next day a few are missing. A week later only one or two still feel familiar.
If you only cram words, repeating them many times in one sitting and then moving on, you mostly feed your short-term memory. The curve then wipes out your work over the next few days. That is why so many learners say “I studied for hours, but nothing sticks” or “I recognize the word, but I cannot recall it when I speak”.
The problem is not you. It is how the brain handles unused information.
The simple trick: interrupt the curve at the right time
The curve is not fixed. Every well-timed review lifts it up again. If you meet a word just before you are about to forget it, your brain gets a strong signal:
“We are using this again. Keep it.”
This is the basis of spaced repetition: you review at growing intervals instead of repeating something twenty times in a row.
A typical pattern for a new word looks roughly like this:
- a first review shortly after you learn it;
- another one later the same day;
- then the next day;
- then after a few days, a week, a couple of weeks, a month.
Each time you remember the word, the gap before the next review grows. If you forget it, it comes back sooner. Instead of one long, tiring session you get short, targeted reviews that tell your brain the word matters.
Why paper flashcards struggle with this
You can copy this by hand with paper cards and boxes for “review in 1 day”, “review in 3 days” and so on. Some people do. It is messy: you calculate every date yourself, you shuffle cards constantly, and the system collapses the first week life gets busy.
Paper cards also have no audio, so you train your eyes and nothing else.
How My Lingua Cards uses the forgetting curve for you
My Lingua Cards is built around spaced repetition, not as an extra feature but as the core engine. You do not think about dates, intervals or boxes. You open the app and continue the session that is waiting for you.
1. Every word is tracked separately
For each word the app keeps a small history: whether you remembered it easily, hesitated, or forgot it completely. A word you know well moves further into the future. A word you struggle with comes back sooner, so most of your time goes to the words that are actually at risk.
2. Words appear right on the edge of forgetting
The aim is to show you a word just before it disappears. From your side it feels almost like a trick: something you have not seen for weeks pops up, you think “I know this… just about”, you recall it, and the memory gets noticeably stronger.
3. Audio turns each review into listening practice
Every card comes with audio. When you play the word you are not only revising; you are connecting sound, meaning and spelling in one memory. That is harder to lose than spelling alone.
4. Two directions: from “I recognize it” to “I can say it”
Remembering a word when you see it is not the same as producing it when you speak. My Lingua Cards trains both directions: the learning session shows you the foreign word and asks what it means, and reverse practice runs as a separate companion session, where you see the meaning and have to produce the word yourself.
From an Ebbinghaus point of view the order makes sense: first you stabilize the memory with spaced repetition, then you stretch it by speaking.
What to do day to day
You do not need the math behind the curve to benefit from it. A simple routine is enough. Open My Lingua Cards once or twice a day and clear the cards that are due; the app chose them for a reason. When a card appears, look at it, say the answer aloud before you turn it over, then listen to the audio and copy the pronunciation.
You do not need marathon sessions. Ten or twenty minutes a day is usually enough, as long as you keep coming back. Short and regular beats rare and long, and with spaced repetition the difference is dramatic.
Stop forgetting words: review them at the right time
If the same words keep slipping away, the problem is usually timing rather than memory. A word you learn once and never revisit fades fast. The same word met again just before it disappears has a real chance to stay.
That is the whole idea behind spaced repetition. My Lingua Cards brings words back at the right moment, so you never have to guess what to review today: it tracks your progress and shows the words that need attention, with the pronunciation and a real example next to each one, in both directions, day after day.
You are not just looking at words. You are training your memory to find them again.
