PETER MARK ROGET (1779--1869) was a British lexicographer and physician. Roger's Thesaurus, a standard reference work for over a century, represents his highly personal view of how the English language reflects the structure of the universe. In some ways, that view is dated today; but the complex structure and breadth of the thesaurus still prove surprisingly helpful to the modern user. Probably the most comprehensive thesaurus on the market. For virtually any word search, it is guaranteed that you can find the most appropriate word with the utmost assurance because of its succinct definition.
