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. Also (by Bell and others), the vanish (or brief final element) or the brief initial element, in a class of diphthongal vowels, or the brief final or initial part of some consonants. Note: The on-glide of a vowel or consonant is the glidemade 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.
3.(Aeronautics) Movement of a glider, aeroplane, etc., through the air under gravity or its own movement.
