This book "supplies a vocabulary of English words and idiomatic phrases 'arranged … according to the ideas which they express'. The thesaurus, continually expanded and updated, has always remained in print, but this reissued first edition shows the impressive breadth of Roget's own knowledge and interests."
The authors present a computer program and instructions for developing reading materials in languages with little or no background in literacy. The book is structured as a how-to manual with step by step procedures to establish an appropriate primer sequence and to organize words, phrases, and sentences that correlate with the sequence. It presupposes a thorough knowledge of linguistics.
