A Short, Frequent Repetition Method for Foreign-Language Vocabulary

Stop Memorizing for 30 Minutes at Once

Almost everyone has had the experience of opening a vocabulary book, memorizing 50 words for 30 minutes, and then remembering less than half the next day. Our brain treats information as important not because we stared at it for a long time, but because we met it again just when we were about to forget it. So even with the same 30 minutes, splitting it into ten 3-minute sessions makes the words last much longer than using it all at once.

3 Minutes a Day x 4 Times, Only 20 Words

Set your daily goal at 20 words. 3 minutes after brushing your teeth in the morning, 3 minutes right after lunch, 3 minutes on the way home from work, and 3 minutes just before bed. In each session, flip quickly through all 20 words from start to finish, spending no more than 5 seconds on each word. If you do not know one, look at the meaning and simply move on. Struggling over a single word is the least efficient thing you can do.

Arrange to Meet Today’s Words Again a Few Days Later

1. Group words into sets of 20 using small cards or an app, and make them your 'today set.'
2. On that day, review all 20 words 4 times using the 3-minute sessions described above.
3. The next day, learn 20 new words, but insert yesterday’s set at the very beginning for just 1 review.
4. After 3 days, 7 days, and 14 days, take out the same set once more each time.
5. During these 4 reviews, remove any word you can recall within 3 seconds from the set, and carry only the words that made you pause into the next cycle.

The key is not 'once today and once tomorrow,' but gradually widening the intervals. When you increase the gaps like 1 day, 3 days, 7 days, and 14 days, the brain repeatedly experiences the feeling of 'I almost forgot that,' and memory becomes strongest at that moment.

Lock in Memory with One Example Sentence

If you only look at a word and its meaning, you may recall it on a test but fail to use it when speaking. For words that get stuck, write one short example sentence together with the word instead of only the meaning. For example, with 'reluctant,' a sentence like 'He was reluctant to apologize' is fast and effective because it places the word directly in a usable sentence.

A System Where Only Stubborn Words Survive

The real advantage of this method is that the number of words you need to review decreases over time. Words you already know drop out, and only the difficult words that remain confusing stay in the set. After a month, the set naturally turns into 'my weak-word list.'
