About Missing Workbook
The Missing Workbook is an English vocabulary learning platform for people who want a deeper, more nuanced command of the language. It aims to fill gaps left by standard English education through a dictionary and structured study tools that cover words, phrases, idioms, roots, and affixes. Learners can explore meanings and shades of nuance, hear and practise pronunciation using IPA, and see how words connect through the Etymology Atlas.
Study cards use spaced-repetition scheduling, including FSRS-5 and SM-2, to help users review and retain vocabulary over time. The site also offers a free vocabulary-size test and lets visitors browse dictionary entries without first creating an account. Access is free for A1-level material, while A2–C2 content is available with Pro; the site says no payment card is needed to get started.
The Missing Workbook is currently in beta and invites users to report bugs or suggest improvements. It presents language learning as a long-term craft, with the goal of helping learners develop greater precision and sophistication in English
