This book is about investigating the way people use language in speech and
writing. It introduces the corpus-based approach to the study of language,
based on analysis of large databases of real language examples and
illustrates exciting new findings about language and the different ways
that people speak and write. The book is important both for its
step-by-step descriptions of research methods and for its findings about
grammar and vocabulary, language use, language learning, and differences in
language use across texts and user groups.
