Vocabulary books and decks

How vocabulary actually sticks

Recognition is easy and retrieval is hard, which is why reading a word list feels productive and produces almost nothing. A vocabulary book on Omniversail schedules each word for review just before you would forget it, and tests recall rather than recognition.

What is inside a deck

• Themed word groups with example sentences and native audio.
• Definitions, pronunciation and usage notes.
• Drill modes for recognition, recall and production in context.
• Scheduling that adapts to how you actually perform on each word.
