Preface
The ancient Romans said that in matters of language, usage is more powerful than Caesar.Their
language was Latin, but this saying applies to English at the end of the 20th century as well. There
is no central authority that decides what is and is not correct; it is all those who speak and write
English, either as their first language or as a language they have learned later in life, who deter-
mine the ways in which the language grows and changes.
This dictionary describes the ways American English is used now--what words mean, how they
are pronounced, their usual grammatical behavior, and typical contexts in which they appear. It
was written using the Cambridge International Corpus, a computerized collection that includes
some 100 million words of written and spoken American English taken from recent books, mag-
azines, newspapers, radio and television broadcasts, and even telephone conversations. This re-
source provides substantial evidence of how words are used, which allows dictionary writers to
describe the language accurately and to give examPles that are based on genuine, present-day
writing and speech.
The Cambridge Dictionary of American English has a number of features that make it a very
. user-friendly dictionary: GUIDEWORDS help you fmd the meaning of a word you are looking for;
LANGUAGE PORTRAITS explain the complexities of English, from ~ddresses" to "Zero";
IDIOMS and COMPOUNDS are defined within the entry for their first important word; the
IDIOMS INDEX helps you find an idiom even if you only can remember part of it; USAGE
LABELS tell you when a word is appropriate, and when it is not; USAGE NOTES give additional
information about a word; and FULL COVERAGE of the words and phrases that students of
American English will want to look up.
Every effort has been made to make this book the most accurate, realistic, up-to-date, and help-
ful tool of its kind. Like many types of tools, it will become even more useful as you become more
familiar with it. The following pages explain the various features of CDAE and how to make the
dictionary work for you. We hope this book will help you to master the challenging language
known as English, so that your usage will help influence the ways in which it changes and grows
during the 21st century.
