In keeping with the American Heritage® tradition of cutting-edge research, the Fifth Edition represents the work of a dedicated team of experts, scholars, and contributors. Thousands of definitions have been revised in rapidly changing fields such as astronomy and biology, geographical entries and maps have been completely updated, and the dictionary’s signature feature notes on word history, synonymy, and language variation have been enhanced and improved.

Word meanings are made easier to understand with thousands of new quotations from classic and contemporary writers. Etymologies explaining word origins and development have been newly created or revised to reflect the very latest scholarship. Many words are traced back to their roots in prehistory through two unique appendices showing word roots in ancient Indo-European and Semitic.

Reliable, enlightening, and visually stunning, the Fifth Edition of The American Heritage® Dictionary of the English Language gives you the opportunity to make your mark in the best possible way.
