What I would like to discuss has little to do with the content of Heloise Lynn’s paper, which beautifully illustrates S‐wave birefringence in near‐surface materials. My concern is with the terminology. Inappropriate use of the term azimuthal anisotropy has become so prevalent in both oral and written presentations that someone needs to point out clearly and in detail why such usage is ill‐advised. My comments, thus, while triggered by the usage of this paper, are for an audience that includes many besides the paper’s author.
