The American Heritage College Dictionary

The American Heritage RM Dictionary of the English Language has been recognized for quality, innovation, and timeliness since its inception. Among the distinguishing features of the dictionary are its clear, elegant defining style, its extensive usage guidance, and its unique Appendix of Indo-European Roots. Since its best-selling debut in 1969, users have come to depend on its accessible definitions along with its rich and informative illustrations, now printed in full color in the Fourth Edition. The American Heritage RM line includes dictionaries for every age level, from preschool through college, and our thoughtful approach to dictionary-making has made our dictionaries the first choice of teachers, parents, and students.
