The Definition Game

The encyclopedia reads you one of its definitions with the headword struck out; you name the entry from four candidates. Ten rounds, drawn fresh from all 6,914 entries — no two games are ever the same.

Rights & ReuseThe complete text of Aiton’s Encyclopedia (1910) is in the public domain in the United States — like all works published before 1928 — and is free to read, download, quote, teach from, and reuse.
