Roget's Thesaurus is a widely used English-language thesaurus, created in 1805 by Peter Mark Roget, British physician, natural theologian and lexicographer. It was released to the public on 29 April 1852. The original edition had 15,000 words, and each new edition has been larger. The Karpeles Manuscript Library Museum houses the original manuscript in its collection.
The name "Roget" is trademarked in parts of the world, such as the United Kingdom. By itself, it is not protected in the United States of America, where use of the name "Roget" in the title of a thesaurus does not necessarily indicate any relationship to Roget directly; it has come to be seen as a generic thesaurus name.
Roget described his thesaurus in the foreword to the first edition:
It is now nearly fifty years since I first projected a system of verbal classification similar to that on which the present work is founded. Conceiving that such a compilation might help to supply my own deficiencies, I had, in the year 1805, completed a classed catalogue of words on a small scale, but on the same principle, and nearly in the same form, as the Thesaurus now published.
