LexForge
A lexicography game for ages 15–18: a word is on trial. Weigh the evidence, then rule — is it in the dictionary, disputed, or not a word at all? Discover how dictionaries really decide (usage, not authority, makes a word), and why some real words look invented and some invented ones look real. On-device; nothing leaves your device.
▶ Play it nowBuilt for sittings of about 25 minutes on the screen. That is our design budget, not a measurement.

Meet the cast
LexForge's cast are guides for ages 15–18 (no illustrated storybook): Docket convenes the court, Usus argues that usage makes a word, Corpa brings the evidence of use, and Glossa checks for a settled meaning.
Docket
the adjudicator — weigh the evidence, then rule
Usus
Descriptivism — usage, not authority, makes a word
Corpa
The evidence of use — how widely, and for how long
Glossa
The settled meaning — does it mean one agreed thing?
