    By keithgreen
    I enjoy a good dictionary. I count on it not for usage definition but it’s historical origin and usage.

  • The Best Dictionary

    By Jesse_usmc
    This is the best dictionary in circulation. I especially enjoy the indexes of word origins. I didn’t write the 2 sentences above; my iPhone auto generated it, but it’s true!
  • Definitely my go-to dictionary

    By Shabkar
    I have a PhD in English and this is my favorite, everyday dictionary. Two features really stand out: the Usage Notes and the etymologies. The Usage Notes give you authoritative advice on difficult points of grammar and usage from a diverse panel of experts. The etymologies are in a class by themselves. They trace words back to their Indo-European and Semitic roots. I have not seen anything like that in another dictionary.
  • Love This Dictionary!

    By Killianx89v
    My one complaint is that it would be nice to be able to copy & paste certain parts of a definition
