Why invented Korean words are so convincing
Korean builds an enormous share of its formal vocabulary by combining Sino-Korean morphemes, each of which carries a stable meaning and can attach to many others. That productivity is a gift when you are learning and a problem when you are being tested, because an invented two-syllable compound assembled from two real morphemes reads as a word you might simply not have encountered yet.
Native Korean words behave differently. They resist recombination, so a fake built in that layer tends to sound wrong immediately even to a learner. If you find the Sino-Korean items much harder than the native ones, that is the test working as designed rather than a gap in your knowledge.
How the scoring resists guessing
Real and invented words are mixed, and your score averages two separate things: the proportion of real words you accepted and the proportion of fakes you correctly rejected. Accepting everything therefore lands you at fifty percent, which is chance — the same result as answering without looking. Rejecting everything does the same.
The verified word count applies the same logic to a size estimate. A raw self-report is inflated by half-recognition; correcting it with the rejection rate produces a figure that survives being checked, which is why this test reports a lower and steadier number than a simple checklist would.
Answering accurately
- Trust your first reaction. If a word needs analysis, you are reconstructing it from parts rather than recognising it.
- Do not accept a word because both syllables are meaningful. That is exactly how the fakes are made.
- Ask whether you have heard it said, not whether it could exist. Almost anything could exist in Korean.
- Say no when unsure. The scoring punishes a false acceptance more than a cautious rejection.
- Keep a steady pace through all sixty. Fatigue in the last stretch shows up as a sudden run of yes answers.
Frequently asked questions
How is this different from the self-report vocabulary test?
The self-report test asks you to check words you know — fast, but it relies on honesty. This check makes you judge every word as real or fake, so over-claiming is punished automatically: accepting fake words lowers both your accuracy score and your verified word count. Take both and compare!
What is a good accuracy score?
50% means pure guessing. Around 60–70% is typical for intermediate learners, 80%+ suggests advanced proficiency, and 90%+ is native-like — those are the ranges reported for LexTALE-style tests in research settings.
Can I get on the leaderboard?
Yes — unlike the self-report test, this score is objective and cheat-resistant, so it feeds a global leaderboard. Submit your accuracy score with a nickname after the check.
How many Korean words do I need for everyday conversation?
Estimates vary, but the most frequent 1,000–2,000 Korean words cover the bulk of casual daily speech, and study guides often cite several thousand for comfortable conversation on varied topics. Your verified word count here tells you roughly where you stand on that path — retake it as you study to watch it climb.
How are the fake Korean words made?
They follow Korean sound and spelling rules — plausible syllable combinations that a real word could use, but that carry no meaning in the dictionary. That's why you can't filter them by look alone; only actually knowing Korean vocabulary lets you tell them apart reliably.
Can native Korean speakers take this check too?
Absolutely — it works at every level. Native speakers usually land in the 90%+ range, so it doubles as a fun challenge among Korean friends, while learners can use the score to track progress objectively over months of study. Vocabulary researchers use this same real-or-fake format with native speakers too.
