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."

Linguistic history and cultural history are closely related. This is demonstrated in the study on the phenomenon of linguistic politeness in French requests, e.g. requesting, ordering, suggesting and advising. On a purely linguistic basis, there are indications of a development away from the concept of medieval politeness, which was primarily based on building up close relationships to a concept which among other things takes the personal freedom of the interlocutor into consideration. This change can be explained with general intellectual developments.
