Linguistics for Language Learning: An Introduction to the Nature and Use of Language. This book is first and foremost for learners of another language and their teachers. It is also for future language teachers. In a more general way it is for anybody who would like to know more about the nature and use of language, especially as it is manifesting itself across the obvious differences between languages.
