R. M. W. Dixon begins by outlining what he feels are the essential components of any language, such as the ability to pose questions, command actions, and provide statements. He then discusses desirable features including gender agreement, tenses, and articles, before concluding with his view of what the ideal language would look like - and an explanation of why it does not and probably never will exist. Written in the author's usual accessible and engaging style, and full of personal anecdotes and unusual linguistic phenomena, the book will be of interest to all general language enthusiasts as well as to a linguistics student audience, and particularly to anyone with an interest in linguistic typology.
