Liquid and fluid are not physically equivalent terms: liquid is, as related to sound, a subset of "fluid." The definition fails to spell out that sound, as most often experienced, is propagated in a fluid. (Air is a fluid. So is water.) Granted "liquid" and "fluid" are similar terms for the great unwashed, but I am being picky with a dictionary since it is a dictionary. Precision in definition aids discussion more than it hinders it, IMO. Your spelling out the propoerties of sound was thus a good idea. :)

That not paticularly relevant here however. With reference to this subject we are only deserning if the word "sound" refered to the reception or transmision. And actually the definition was fine because it was listing all mediums sound could move through.
The nature of fluids is particulary important with respect towaves, but as my simple definition spointed out it can also be tranmitted by solids, so I think my simple definition best address this simple topic.
