You look up a word. Five minutes later, you need it again, but it's gone. How many times are you supposed to look up the same word before it finally sticks in your brain? Linguistic research gives us a surprisingly specific number.
The Magic Number: 7 to 15 Exposures
Most linguistic studies agree that a language learner needs to encounter a word between 7 and 15 times in various contexts before it becomes part of their active vocabulary. But there is a catch: you cannot just read the word 15 times in a row on the same day.
These exposures need to be spread out over time. This is where the concept of Spaced Repetition (SRS) becomes practical.
Automating the 15 Exposures with Colt App
Keeping track of how many times you've seen a word is impossible on your own. Colt App tracks every single exposure for you. Whether you see a word in a flashcard quiz, or hear it in one of our audiobooks, our algorithm counts it. It ensures that you hit those optimal 15 exposures efficiently, moving words from short-term to permanent memory.
Conclusion
Don't get frustrated when you forget a word you just looked up. Your brain is working exactly as intended. Just trust the process, ensure you get enough varied exposures, and let the algorithm do the tracking.
