What is Gliding?
Gliding (Gl), also called Liquid Gliding or Liquid Simplification, is a phonological process typically present up until the age of 4 years.
Gliding involves the replacement of a pre-vocalic liquid - /r/ or /l/ in the initial position of a word or syllable - with a glide - “w” or “y” sound. Gliding can effect /r/ or /l/ in single consonants or within clusters.
Examples:
drive = dwive
late = wate or yate
rake = wake or yake
slide = swide
taller = tah-wer or tah-yer
