Glide
Definition:
(n.) The glede or kite.
(v. i.) To move gently and smoothly; to pass along without noise, violence, or apparent effort; to pass rapidly and easily, or with a smooth, silent motion, as a river in its channel, a bird in the air, a skater over ice.
(v. i.) To pass with a glide, as the voice.
(n.) The act or manner of moving smoothly, swiftly, and without labor or obstruction.
(n.) 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, // 19, 161, 162). 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 (see Guide to Pronunciation, // 18, 97, 191).
Example Sentences:

(5) Since 1970, when the flexor tendon gliding mechanism of the finger has been damaged in the area of "no man's land" and conditions are less than optimal for conventional tendon grafting, the authors have attempted to graft a fascial tube including tendon and paratenon of the palmaris longus.
