Read today’s word

A generous little dictionary that keeps you company

  1. Everything about a word is included

    How to say it, what it means, how to use it, synonyms, similar words and where it came from are all part of the app. Nothing about a word is held back for a subscription.

  2. A daily word that is new to you

    The daily word never repeats. Tap “I know this” and that word is never offered as the daily word again.

  3. Search by meaning

    Type an ordinary word like “happy” and Vocabulum finds rarer words that mean something close to it.

  4. Private by design

    No account, no ads, no tracking and no pictures. The word is the picture, set in type.
