   2. (Phon.) A transitional sound in speech which is produced
      by the changing of the mouth organs from one definite
      position to another, and with gradual change in the most
      frequent cases; as in passing from the begining to the end
      of a regular diphthong, or from vowel to consonant or
      consonant to vowel in a syllable, or from one component to
      the other of a double or diphthongal consonant (see Guide
      to Pronunciation, [sect][sect] 19, 161, 162). Also (by
      Bell and others), the vanish (or brief final element) or
      the brief initial element, in a class of diphthongal

         in passing to it, the off-glide, one made in passing
         from it. Glides of the other sort are distinguished as
         initial or final, or fore-glides and after-glides. For
