Is there a comprehensive list of Weirding words to be used with the Weirding Module in the Dune universe? There are several obviously pronounced in the original movie. In the movie, Mua-Dib is a 'killing' word, but I couldn't actually find a list of these words anywhere. I'm interested in both cannon and non-cannon words.
There are no canon words, because the whole idea is non-canon. Although you mention the novel, this concept is unequivocally not present in any of the novels.
In the books, "the Weirding Way" is a phrase the Fremen use to describe the superlative physical and mental training developed by the Bene Gesserit. It has nothing at all to do with sonic weapons.
In the novel, the closest thing to word weaponry can be found listed in the "Terminology of the Imperium" section at the end of the book:
"UROSHNOR: One of several sounds empty of general meaning and which Bene Gesserit implant within the psyches of selected victims for purposes of control. The sensitized person, hearing the sound, is temporarily immobilized."
Sound design is central to David Lynch's films. With Dune, he used the interior voice-over to tremendous effect (that trick usually never works), he used distortion etc with The Voice, and he invented the sound weaponry element. Non-canonical, but brilliant.
