This book is an extremely detailed and comprehensive examination of conditional sentences in English, using many examples from actual language-use. The syntax and semantics of conditionals (including tense and mood options) and the functions of conditionals in discourse are examined in depth, producing an all-round linguistic view of the subject which contains a wealth of original observations and analyses. Not only linguists specializing in grammar but also those interested in pragmatics and the philosophy of language will find this book a rewarding and illuminating source.
