You memorised it but cannot say it — storing versus retrieving
You memorised three thousand words, and when you finally speak, none of them arrive. Nothing was lost. You practised putting words in and never practised getting them out. Most flashcard apps only train the easier direction, foreign word to meaning; what consolidates memory is retrieval practice — seeing the meaning and recalling the word yourself, then saying it aloud. Tokkly's vocabulary feature schedules spaced repetition automatically, moving correctly-recalled words further out and shaky ones back sooner, with a timed spoken-recall step.
Knowing a word versus retrieving it
"See apple, think 사과" is recognition — the direction from word to meaning.
Speaking needs the opposite direction: from the idea of an apple, pull out the word apple. That direction barely improves unless you train it deliberately.
Most flashcard apps put the foreign word on the front and the meaning on the back, so you keep drilling the easy direction.
Retrieval is what builds the memory
Memory consolidates when you pull something out, not when you put it in. The harder you had to work to recall a word, the longer it stays. That testing beats re-reading is one of the most repeatedly confirmed findings in learning research.
So good vocabulary practice is not "look and confirm" — it is "try to recall". Seeing only the meaning and saying the word aloud is the simplest and strongest form of it.
Spacing the repetitions
Cram in one sitting and most of it is gone the next day. Words last when you meet them again just as you are about to forget.
Tokkly's vocabulary schedules that spacing for you: words you get right move further out, shaky ones come back soon. You do not have to plan anything.
Say it out loud or it stays inside
A word recalled only in your head still arrives late in conversation. Saying it aloud is what gets the muscles of your mouth to remember too.
A timer sharpens it. See the meaning and say it before the clock runs out — Tokkly's ⚡Speed Speak starts around five seconds and tightens the faster you answer. Whatever survives that condition is a word you can actually use.
Common questions
How many words do I need to hold a conversation?
The most frequent 1,000–2,000 words cover a large share of everyday conversation. But 1,000 words you can retrieve are worth more than 5,000 you merely recognise.
Should I memorise words inside sentences?
Meeting a word in a sentence keeps its usage attached, which helps. But memorising whole sentences and retrieving that word to build a new sentence are different things — you need both.
