Made, as a vowel, with a less tense, and more open and
   relaxed, condition of the mouth organs; -- opposed to primary as used
   by Mr. Bell, and to narrow as used by Mr. Sweet. The effect, as
   explained by Mr. Bell, is due to the relaxation or tension of the
   pharynx; as explained by Mr. Sweet and others, it is due to the action
   of the tongue. The wide of / (/ve) is / (/ll); of a (ate) is / (/nd),
   etc. See Guide to Pronunciation, / 13-15.
