Why Korean words you read easily disappear when spoken
Korean liaison and sound-change rules mean the word you studied and the word you hear are often different objects: 있어요 reads cleanly on a flashcard but arrives as 'i-sseo-yo' in a drama at native speed. If your review only ever shows you the written form, listening comprehension stays years behind reading.
Korean also surrounds learners with near-duplicates — similar verbs split by politeness level, Sino-Korean vs native Korean number systems, and adjective pairs that translate identically into English. A plain word list gives you no machinery for telling them apart, so they blur together and errors fossilize.
How FreeLingo helps
FreeLingo starts from TOPIK-graded word books, everyday scene sets, or your own imports — song lyrics, subtitle screenshots via OCR, or class handouts. Each plan schedules review at 30 minutes, 12 hours, then 1, 2, 4, 7, 15, and 30 days, with overdue words resurfaced first.
Review modes attack the two Korean-specific problems directly: listening mode plays the real pronunciation so sound changes become familiar instead of surprising, and similar-word tests plus AI Confusion cards force you to separate the near-duplicates a list would let you blur.
