Laryngeal

After Tom came to learn that he was suffering from laryngeal cancer, his vocal cords were removed, and he now breathes through a hole in his throat.

At sight of it there commenced a series of laryngeal spasms, with clutchings at his throat, far more violent than any I had heretofore seen.

The vowel-coloring effects of the IH laryngeals cannot be considered apart from the vowel-reducing effect of the IH stress accent[…]

[…]it is not only different from Buck's in the linguistics (laryngeals have seen to that); it is very different in scope and aim.

Finally, it should be noted that laryngeals not adjacent to syllabics were apparently deleted by three different rules.
