This little book aims to give a certain perspective on the subject of language rather than to assemble facts about it. It has little to say of the ultimate psychological basis of speech and gives only enough of the actual descriptive or historical facts of particular languages to illustrate principles. Its main purpose is to show what I conceive language to be, what is its variability in place and time, and what are its relations to other fundamental human interests - the problem of thought, the nature of the historical process, race, culture, art. The contents of this book are: Language Define; The Elements of Speech; The Sounds of Language; Form in Language; Grammatical Processes; Form in Language; Grammatical Concepts; Types of Linguistic Structure; Language as a Historical Product: Drift; Language as a Historical Product: Phonetic Law; How Languages Influence Each Other; Language, Race and Culture; and Language and Literature.
