The 8,000 most important English words, split into six levels (L1–L6) by frequency and learning value, aligned with CEFR bands and the Taiwanese curriculum vocabulary ladder. Open a level to browse its words, tap any word for the dictionary, or start a leveled practice run — results feed the same spaced-repetition schedule as every other mode.
Levels are built independently from open frequency data (wordfreq × NGSL) and align with official word lists by size tier, not word-for-word.

Academic and low-frequency vocabulary for university texts and international exams.
