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."
Extra-grammatical morphology is a hitherto neglected area of research, highly marginalised because of its irregularity and unpredictability. Yet many neologisms in English are formed by means of extra-grammatical mechanisms, such as abbreviation, blending and reduplication, which therefore deserve both greater attention and more systematic study. This book analyses such phenomena.
