What VocabularyBase offers
The site brings together a dictionary of 79,285 entries, 300 word lists, 120 learning guides and starter vocabulary for 32 other languages. Authored learning entries give examples and a usage note; licensed reference entries identify their source and sense.
You can practise with flashcards and short quizzes, play the word match game, print worksheets and Frayer models, or build your own quiz with the quiz maker. Nothing requires an account.
Who it is for
- Students who meet an unfamiliar word in a lesson, book or exam practice.
- Adults and English learners who want plain definitions with realistic examples.
- Teachers and parents looking for ready-to-use lists, worksheets and quizzes.
- Anyone curious about a word, a commonly confused pair or a phrase they keep hearing.
How our content is produced
Choosing what to cover
We use search research to see which words, lists and questions people look for most, then group those searches by what the reader actually needs: a definition, a list, a practice activity or a guide. Searches for other publishers’ answer keys or brands are deliberately left out.
Writing and licensed sources
Authored entries, lists and guides are drafted with the help of AI writing tools under a written editorial standard. Authored entries use original examples. Reference entries reproduce definitions from Princeton WordNet or English Wiktionary and show the source, sense identifier and applicable license on the page.
Automatic checks
Every time the site is built, automated checks confirm required fields and provenance, collection references, links, and unique page metadata. Entries that fail are not published.
Human review
Not every entry has yet been individually reviewed by a human editor. We are working through the most-used pages first and fix errors as soon as they are reported. If something looks wrong, please tell us.
Editorial principles
- Plain language first. A definition should be understandable without looking up other hard words.
- Original examples. Example sentences are written for this site to show a word in natural use.
- One sense at a time. The most common meaning comes first; other common meanings are listed separately.
- No invented facts. We do not publish made-up statistics, quotations, people or credentials.
- Honest labels. Informal, vulgar and offensive words are defined for understanding and are clearly labelled as such.
- Independence. Grade and exam lists are our own practice selections, not official lists, and we are not affiliated with any exam organisation.
Corrections and feedback
We welcome corrections. Use the contact form with the subject “Correction or feedback” and include the page address and what should change. Confirmed errors are corrected on the next site update.
Independence and funding
VocabularyBase is an independent website. At present it shows no advertising, publishes no sponsored content and contains no affiliate links. It uses no analytics or tracking services. If that ever changes, we will update this page, our disclaimer and our cookie policy first.
A simple, private workspace
