Several thousand words, organized across four difficulty levels.
Free to study right here in your browser — no download.
Each word you study gets its own page: the English definition, the meaning in Chinese, Spanish, Korean and Vietnamese, a pronunciation guide with the syllable split, and an ISEE-style practice question with the answer explained.
Choose your level and the language you want meanings in, and the session starts at the first word of that level — use Previous and Next to move through it, and Mark as Mastered to keep score as you go.
To carry your progress across devices, get reminders, and practice with adaptive tests and spaced repetition, download the iSEE Vocab app — it uses the same word bank.
Pick the language you want word meanings in, then your level, and go.
Content is organized by difficulty so students build a foundation before tackling advanced vocabulary. Pick a level to start there.
The iSEE Vocab app tracks every word you master across sessions and devices, and builds adaptive tests from what you get wrong.
