Vocabulary sticks when you meet a word in a sentence you wanted to read, star it there, and review it later in the form you met it in. A word learned from a list is a word you can recognise on a card. A word learned from a page is a word you can use. That gap is why a 90% score on a 2,000-word deck does not survive a novel's first page.
Every learner hits the treadmill point. Reviews green, streak intact, and then a novel where none of the drilled words turn up. Your brain discards what arrives with no context, and a card is exactly that: a string, a gloss, no situation.
The illusion of competence in vocabulary lists
A flashcard tests you under conditions the language will never offer: English prompt, dictionary form, nothing on either side. Get it right twice and you file it under known.
Take かける. Your deck says to hang. Read for a week and find it doing this:
- めがねをかける
- to put on glasses
- 電話をかける
- to make a phone call
- 腰をかける
- to sit down
Same with 覚える, on your cards since month one. To memorize. Here it is, working:
この漢字はどうしても覚えられない。
直訳 Word by word
This kanji, no matter what, cannot be remembered.
覚える in the potential form, negated, with どうしても leaning on it. You will remember this one, because it annoyed you.
Learning a verb without the particle it takes. 会う means to meet, so you write 友達を会った. It is 友達に会う. No card had room to tell you: the particle only exists in a sentence.
Why reading is where vocabulary actually sticks
Read authentic Japanese native content and the useful words come back on their own: twenty pages of a novel will hand you the same few hundred words again and again, each time doing a slightly different job. Every encounter also brings luggage. The word sat in a scene, next to somebody in a mood, so later you are not searching an index of strings, you are pulling one thread of a web.
Then there is the guess. Work a word out from the sentence before you tap it, and that retrieval is the exercise. A deck hands you the answer key first, which is why it changes so little.
The seconds you spend guessing before the lookup are worth more than the lookup. Do not let your reading tool be so fast that it takes the guess away.
The vocabulary loop in Yomimaru
Every reader can look a word up. The trick is doing it without losing the sentence you were in.
- Tap the word. Tap whatever stops you in a news article or a Sōseki chapter. Its readings, its part of speech and its numbered English meanings come back over the text.
- Star it. One tap, and the word goes to your list in the form you actually met it in: 食べた, not 食べる. The title of the text goes with it. The part you would otherwise copy out by hand, and never do.
- Review it in-app. Every starred word carries a mastery score mapped onto an SRS stage, so words you keep meeting drop out of rotation.
- Or send it to Anki. Export the list and each row carries the expression, its reading, its meaning, an SRS tag, a suggested interval, the conjugated form you tapped, and the title of the text it came from.
An SRS is a scheduler, not a teacher. It decides when a word comes back; what comes back is whatever you saved. So keep reading: the same words will find you again in a new sentence. That is the review no deck can fake.
Actionable tips for vocabulary mastery
Star less than you want to. At N4, star N4 and N3 words. Every obscure term you star steals a review slot from a word you would meet again this month.
Vary what you read, too. Read the day's news, a Sōseki short story, and a book you imported yourself, all in Yomimaru. A word you have only ever met in one register is a word you half know.
