"Sentences and Thinking," originally published in 1919, is a practice book in correct sentence making, designed for American college students and for everyone interested in advanced studies of English. It is quite suitable for vigorous language review work and for raising awareness and improving English conversational and written skills. The authors have sought absolute essentials. Moreover, their exceedingly sensible approach asks readers to think out the reasons that lie behind grammatical and rhetorical rules. The heart of the book is a study of the principles of subordination, parallelism, emphasis, economy-all of which demand the prerequisite of clear thinking. "Sentences and Thinking" is an indispensable tool for English for academic purposes. Part of the project "Immortal Grammar Series" of classic literature, this is a new edition of the classic work published in 1919-not a facsimile reprint. Obvious typographical errors have been carefully corrected and the entire text has been reset and redesigned by Pen House Editions to enhance readability, while respecting the original edition.
