  • American Heritage Dictionary

    By Bert Lain
    This app, and this dictionary, are in a class by themselves. Thanks to the incomparable work of the late Calvert Watkins, the information with regard to Indo-European roots is both beautiful and illuminating. This dictionary is constantly being brought up to date with regard to contemporary usage. I frequently mention this dictionary in my classes on Greek and Latin language and literature, as well as in my discussions of poetry and prose in English. (Bert Lain)
  • Very nice dictionary

    The AHD has accompanied me since 2015, when I was preparing for my English exams. It is very nice. One suggestion for the app might be: can the “Add to Favorites” icon be displayed on the top menu, rather then being hidden in the foldable menu? I really use function a lot. Thank you.
  • Wonderful APP

    When I look up any word I always understand with accuracy what the meaning of the word is. Explain what part of the speech is in a convenient and easy way. Fantastic.
