How to remember Spanish words: the three-encounter rule

The forgetting curve doesn't care how motivated you are

In 1885, Hermann Ebbinghaus memorized thousands of nonsense syllables and then tested himself at intervals to see how fast they leaked out of his head. The answer: brutally fast. Most of what you learn is gone within days unless something interrupts the slide.

A century and a half later, every Spanish learner re-runs this experiment. You meet aprovechar on Tuesday, feel the little click of understanding, and by the following Tuesday it's a vague shape you'd recognize but couldn't produce. Nothing went wrong. That's just the curve doing its job.

Why one exposure never sticks

Your brain files a single encounter as trivia. It has no evidence the word matters — you saw it once, in one context, and moved on. Storage is expensive, so the default is to let it fade.

What flips a word from trivia to keeper is reappearance. When a word shows up again — in a new sentence, a new voice, a new week — your brain gets the signal it can't ignore: this one keeps mattering. The forgetting slows a little more with each return, until eventually the word just… lives there.

The three-encounter rule

Here's the practical version of all that research: plan for three encounters, spaced out, in different contexts.

1. The meeting. You notice the word and learn what it means. This one's free — it happens whenever you read, listen, or look something up.
2. The reach. A few days later, you try to recall it cold — before seeing the answer. The reach is the workout; the strain is the point. Even failing and re-checking counts.
3. The use. You produce it: say it, write it in a sentence about your own life, drop it in a message. Production is what moves a word from "recognize" to "own."

Notice what's not on the list: rereading your notes, highlighting, or seeing the word on the same flashcard in the same order for the tenth time. Recognition feels like knowledge but it fades like everything else.

How to engineer encounters

The problem with encounters two and three is that real life doesn't schedule them. You might not run into madrugada again for months. So you cheat — you engineer the returns:

Keep one list, not five

Screenshots, notes-app fragments, and that one notebook from 2024 are where words go to die. Pick a single home for every word you meet, and make adding to it a ten-second habit. The list is the raw material for everything else.

Write one bad sentence per word

Not a good sentence — a bad one, about your actual life. "Me da igual el tráfico porque trabajo en casa." Clumsy is fine. The act of assembling the word into your own thought is encounter three, and it beats twenty passive reviews.

Let music and shows do the reps

A song you replay is a spaced-repetition system with a beat. When a saved word shows up in a chorus or an episode, that counts as a full encounter — context, emotion, and audio all at once. Choose media you'd enjoy anyway and the reps happen for free.

The lazy version

All of the above works, and all of it requires you to be the scheduler. That's the part that fails — not the memory, the logistics.

That's the entire reason Spanimo is an email. You save the words; every morning, a short email brings a couple of them back — a cold recall here, a quote or lyric there, one small challenge to write a sentence. Encounters two and three, delivered, so the only thing left for you to do is read for three minutes.
